Ever seen an Arabian come off a 4f/:50 pace and still run the next quarter in a snappy 26 seconds on his way to a 7+ length victory at 8+ furlongs? In doing so, he made up 11 lengths on the rest of the field to the shock of HRTV commentators. You may need to rewind the video a bit as he starts his run completely out of the wide angle viewpoint down the backstretch. He’s #11, nearly white, and second to last around the first turn. The jock celebrates a bit early too, matching my enthusiasm here in Kentucky-
So Big is Better, the champion older Arabian horse of 2012, capped off a remarkable 2013 season with a 7+ length victory in the first ever Breeder’s Cup Arabian race at Santa Anita Park; the $150,000 Grade 1 President of the United Arab Emirates Cup. Owned by Mark Powell and trained by his brother Scott, the 9yo heads off to stud duty with a 10 win season and earnings of $185,220 after a campaign that saw races in Northern and Southern California, Texas, Colorado, Kentucky, and Delaware. Scott estimates they put 7,000 miles on the trailer!
Of note: So Big is Better worked a mile in 1:53 upon his arrival in California, and again breezed a fast 3F the day before his big win. No thoroughbred even worked 8F that week. What few new is that prior to heading to post, he spent October training 6,000 feet above sea level at Quarter Moon Ranch in Arenas Valley, New Mexico.
Remember, the 2 longest odds modern Kentucky Derby winners came from high altitudes the month before the big race:
Here is So Big is Better sprinting 6F barely a second off the Arabian world record last season:
Owner Mark Powell: “The combination of elevation, STORM, and Scott’s conditioning for stamina led to our first Grade 1 win at the best possible time. So Big is Better covered the mile and a sixteenth distance 3 seconds faster than ever before – and against top flight competition.” I’d say so – the connections turned a world-class sprinter into a G1 winner over 8+ furlongs in less than 2 full seasons.
STORM® promotes buffering of lactic acid in muscles by boosting muscle carnosine synthesis, allowing horses to work at maximum speed and power for longer. Muscle carnosine level in Arabians is generally lower than Thoroughbreds and Quarter horses, so STORM® is especially effective at helping them achieve their full potential.
As the all time leader in wins from a son of super stallion Burning Sand, So Big is Better is now available for stud duty, contact Mark Powell for details at firstname.lastname@example.org or 801-638-4111.
Trainer Scott Powell and Lori Long are accepting new trainees at Quarter Moon Ranch and have shown that they will ship all over the country to win big races. For further information please visit www.quartermoonranchllc.com or call Scott directly at 575-654-6129.
So Big is Better stats before Team Powell entered the picture:
38 starts: 15 wins, 9 seconds, 3 thirds and $147,845 in prize money over 5 seasons.
16 starts: 10 wins, 1 second, 1 third and $185,220 in prize money over 2 seasons.
Congratulations to the entire team on a well deserved win and best of luck in the breeding game-
Top trainer Mike de Kock: “When your horse may not have the bloodlines or ability of their opponent, fitness is the one area where you can beat them. Treadmills allow you to get that extra fitness and “the edge”. That is how important they are.”
Treadmill advantages: no rider error, no bad steps/consistent surface, can train during bad weather, less concussion on oft injured horses, vet/groom stand nearby, can scope at racing speeds, can prescribe and follow precise program of speeds/inclines/duration.
Young Thoroughbred horses can increase aerobic capacity and running performance more than by strictly using track training under saddle with the addition of intermittent high-intensity treadmill exercise, and they can do so without experiencing lameness. This finding suggests that young racehorses might be able to achieve higher aerobic fitness during training without subjecting their musculoskeletal systems to increased loading and risk of developing lameness.
The findings of this preliminary study do not indicate a specific protocol to best achieve this goal.
16 pages in length; can be a boring read for those not terribly interested in the science, so I will do my best to summarize:
Study takes place in Japan, where apparently the common ‘wisdom’ is that high speeds in young horses leads to lameness – therefore no speeds higher than a typical gallop are normally introduced into March of the 2yo year. Trotting and slow cantering are the only exercise stimulus applied after the breaking process. It is the belief that anything faster in a young horse will cause injury. The American term for this can be thought of as ‘legging up’ – and was found years ago to be a major cause of shin soreness in the groundbreaking Maryland Shin Study:
Here in America many devotees of the Study begin introducing speed as early as December. Details on that protocol here:
(Off topic: A good European trainer friend of mine believes while the above regimen may indeed strengthen bones and provide ideal development of early speed; it may also (by necessity) ignore cardiovascular development due to shortened gallops. Therefore, since his style of turf racing over longer distances demands superior aerobic fitness, he has made some changes and found great success.)
As in the US; high-speed treadmills in Japan are primarily used for veterinary purposes and/or clinical research. However, many trainers around the world utilize the treadmill as a tool to stimulate aerobic/anaerobic capacities without putting the skeletal system under an increased risk of injury. This study aims to quantify if the addition of a treadmill to typical early conditioning practices can improve measures of athletic performance without causing undue lameness.
Just 12 Japanese juveniles took part in the study and were divided up into 3 groups, all of which undertook identical trackwork sessions under saddle for 8 months.
*Group C left it at this; no treadmill sessions whatsoever – think Conventional
*Group S added weekly treadmill sessions at higher speeds for the final 2 months – think Short
*Group L supplemented trackwork with the treadmill once weekly for the entire 8 months – Long
Treadmill training for Groups S and L involved a single bout of high speed training once weekly. Therefore, Group S was only on the machine 8 times at speed while Group L had 32 treadmill sessions over an 8 month period. Again, this was in addition to trackwork sessions.
Open bars indicated distance walked; striped bars indicate trot distance; solid bars represent canter distances. Grey bars indicate distance variations based on individual speeds. Cantering was under 10 m/s (22mph, or 20sec/f, or 3:00 min/mile) during Nov and Dec, and gradually increased up to 13.5m/s in April for distances up to 1000m. (30mph, or 15sec/f, or 2:00 min/mile).
For groups S and L, there was no trackwork on treadmill exercise days. Instead treadmill sessions were up a 6% incline and speeds were set to elicit exhaustion by 3min time. When a horse lasted the entire 3min comfortably – the next session was at 0.5m/s faster.
Afterwards the 12 subjects were subjected to lameness evaluations, measures of aerobic capacity, VO2max, and running efficiency – through a battery of tests, with the results summarized here:
*None of the 12 horses experienced any lameness throughout the study period.
*Although body weight measurements did not differ significantly overall between the 3 groups; the C group lost a statistically significant amount of weight the final 6 months of the study, while the S and L groups did not. (I believe this was due to the fact that the S and L groups gained muscle from the extra high intensity treadmill workouts.) From June through October of the yearling year everyone gained weight as expected – and through the next testing period (April of 2yo season) everyone lost weight, but the C group lost more.
*As expected, all 3 groups improved their maximum running speeds; yet in the final test both treadmill trained groups (S and L) improved moreso than the C group. VO2max improved across the board but the difference was statistically significant ONLY for the L group vs the C group, and even verged on being statistically greater compared to S. S and C did not differ significantly on this measure.
*Maximum HR decreased for all by an average of 11bpm. (Many exercise physiology texts have previously claimed this not to be the case.) Cardiac output did not differ between groups.
*Both hemoglobin and hematocrit improved dramatically for the L group, reaching a level of statistical significance over groups C and S.
*End of run lactate concentrations did not differ between the groups, neither did V200 – velocity at a HR of 200bpm.
(See study link for all raw data.)
Aerobic metabolism generates the majority of energy during thoroughbred flat races. Therefore, it’s vital to develop these systems, but always taking care not to overload the skeletal structures of the lower leg. The sample size of this study was quite small, 12, therefore the fact that many results between different groups did not approach statistical significance shouldn’t be taken to mean that those differences don’t exist – and would very well be borne out with a larger sample size.
Although no lameness was observed in this small group of 12, the Japanese industry typically sees very low levels of lameness anyway, less than 5%, which is no surprise given the very conservative early conditioning regimens. However, it’s of note that Groups S and L spent much time at higher speeds and still presented as healthy of limb as the control group.
I need more time to read and digest. Let’s try something different and see if readers can fill up the comment section below with opinions. I know there are at least a half dozen guys (and girls) much smarter at this stuff than am I. I think it’s clear that more time on the treadmill produced better results with no increased risk of injury.
But once weekly sessions? Would you go more often?
And each session constituting of running until exhaustion for 3 minutes? Would you cut back on that?
That seems like a low frequency and high duration of exercise to me. Of course, the treadmill incline must be accounted for – which is where my experience lacks. 6% sounds pretty steep, and I see no speeds in here above 13.5 m/s or 15sec/furlong – while our US youngsters following the Maryland Shin Study will hit speeds of 16m/s, 13sec/furlong for example. But that is on the flat, dirt tracks so common in our industry.
Now that the treadmill gives you precise control over speed and incline, would you train your sprinters differently than your routers? How about 2yo vs 5yo? Turf, dirt, synthetic – does that change your conditioning plan?
My favorite time of the year – when ultra fit BC champions find themselves in the sales ring here in Lexington the very following week. Above is Groupie Doll selling for $3.1 million and I believe Mizdirection is also coming up this week. The chance to see a top class sprinter in 100% shape and groomed to sell is a treat for the eyeballs, she looks like a sculpture for crying out loud – and so well behaved, mercy. I got goosebumps standing beside her as she walked into the ring.
Kudos to trainer/owner Buff Bradley and family. They have struck gold twice now, with this mare and with multimillionaire gelding Brass Hat, and I hope they find another gem here shortly. Class, class, class acts. Did anyone catch his emotional reaction after her win at Santa Anita? Even winners can get heartbroken at this game, but to stay alive smaller farms have to take the money when it’s on the table.
Not been writing for a while, but some good stuff coming up. Had 2 big winners at the Breeders Cup last weekend; both on STORM and one doing some very interesting things in addition to the supplement. Press release going out worldwide this week, but I am going to add some pics and video to the story before posting here. One group of connections have given me permission to blog details, but the other shall remain nameless/faceless. It’s tough to finally sell a product you believe in – yet have it work so well that satisfied customers refuse to tout it to the competition – oh well, I guess there are worse problems to have.
One client in Australia recently purchased a treadmill, so exciting work there in the future. Also received a newly published study from Japan ‘proving’ that adding high speed work on a treadmill to a 2yo conditioning program improves athletic development and does not increase lameness. Details to come on that as well.
Above is the actual machine in operation near Paris, KY. Only used a handful of times and retailing for $115,000 this model from Equigym is now available for purchase, please contact the owner directly – as all offers will be considered:
Dana Soucy, Sapphire Creek Farm
And here is a brief video of the machine in action:
And if you are the adventurous type, here is a revolutionary piece of equipment that provides Intermittent Hypoxic Training:
A while back I wrote about how the 2 longest shot Kentucky Derby winners of the modern era both had altitude training in common:
In some countries, this can be managed due to huge geographical differences in elevations between training center and racetracks, but that is mostly impossible in the US outside of New Mexico.
However, Intermittent Hypoxic Training (IHT) has a host of benefits outside of conditioning racehorses, most of which I must confess I never considered.
1. You can acclimatize horses prior to significant air travel.
2. You can enhance the reproductive process in mares and foals by stimulating oxygen metabolism.
3. You can mitigate some of the damage due to EIPH. Remember, even racing with Lasix doesn’t always completely stop pulmonary bleeding.
See the system in action here:
As with the treadmill, please contact the owner directly with any offers. Here is the contact info:

I firmly believe that in the future we will develop the next Secretariat through advances in technology applied to veterinary care and the conditioning process, rather than wait for the genetic lotto balls to magically appear.
Thanks to blog reader Jared for the heads up on this video from the legendary conditioner D. Wayne Lukas, recent appointee to the Kentucky Horse Racing Commission, talking briefly about pulmonary bleeding in racehorses.
Mr. Lukas is an anomaly in our sport today; in addition to being extremely competitive here in 2013, he was also around the game in the good old days – and talks about that here. How does D. Wayne figure we should prevent bleeding? By only sending 100% dead fit racehorses to the post, that’s how. Good for him.
He also mentions how veterinary advances such as the endoscope should come into play, although he doesn’t specify how. I did exactly that for him in this blog post from November 2011:
Lots of good pics in there for reference as to what the various grades of pulmonary hemorrhage look like through a scope. Please check it out before reading on if you want to know the ‘how’.
Lukas will now be in a position with the KHRC to influence how we move forward, away from raceday drugs if he so desires.
In a world without Lasix, perhaps an entry into the high profile 10F Kentucky Derby has to ‘prove’ his horse’s fitness during a 6F work 7-14 days before the big race. It’s not enough just to post a gaudy 6F/1:10 figure on the worktab, but can that same horse show a Grade 2 or better on the scope post workout? Because if he can’t – he’s gonna bleed like a stuck pig on raceday with 4 more furlongs at maximum effort without diuretic use.
That 3yo would have also had to ‘prove’ his fitness a few months earlier before a 9F Derby prep by breezing 5F in 1:00 or better, again demonstrating a Grade 2 or better score. Keep working backwards to his 2yo year and you have 8F races and 4F breeze ‘tests’ for significant EIPH in the absence of Lasix use.
There is still a place for bleeders in this game; give them the injection and race them in non-graded action; but please remove them from the future stallion/mare pool.
I talk to many trainers on the backsides of tracks around the world, and when the camera isn’t on them (and they trust you to keep quiet) they become much more truthful. Just last month a trainer repeated to me a phrase I had read at some point in the past few years that is quite insightful:
With regards to fitness: “Half the time I am guessing, and the other half I am hoping I guessed right.” Judicious use of the scope can remove any ‘guessing’ from this process as pictures don’t lie.
My next post will deal with the concept of ‘Performance Profiling’ – where actual physiological data is collected during/after races to quantify the age old concept of ‘It’s not how fast they go, but how they go fast.’ We need to objectively define racehorse fitness; as doing so can reduce wastage, increase handle, and lessen our reliance on drugs.
Think those Moai know a good stallion prospect? Easter Island has always fascinated me, but for some odd reason it surprised me to realize that this rocky outcropping 2,100 miles from continental South America is a special territory annexed by Chile. It does have a closer neighbor, as about 50 people live on Pitcairn Island – 1,300 miles to the West. Even further West, another several hundred miles, lies Palmyra Atoll – roughly 1,000 miles south of Hawaii – scene of a real-life murder mystery detailed in a cool book by Vincent Bugliosi:
How the hell does one get murdered on an uninhabited desert island? Crazy.
Back to the task at hand. I know a gentleman in Chile who has a group of breeders interested in purchasing an American stallion for permanent stud duty in South America. Budget is always a concern, and these fellows can spend around US$100,000 for a resident stallion prospect (no shuttling), or perhaps would consider renting a stud for the breeding season. Scat Daddy has been a rousing success thus far.
A Kentucky-bred is preferred, and most current standing studs in Chile are not graded stakes winners – so even G3 black type would be a plus from the marketing side. Please submit any possibilities to me via email at email@example.com and I will put you in touch with my connections. Thanks!
Bettor beware, indeed. Current information available to consider when betting on the races is 2 dimensional: numerous variables related only to the stopwatch and the endless track variants. Nothing comes from the horse itself – the invaluable 3rd dimension. What I aim to do is quantify the old adage: ‘It’s not how fast they go, but how they go fast’.
First, some history-
In 1992 the Beyer Speed Figures become a permanent fixture in DRF past performances. Len Ragozin’s ‘The Sheets’ have been around since 1982 at least, and Jerry Brown’s Thorograph service has public mentions going back to 1989. Pace figures, in all their permutations, seem to have their origins since at least the early 1980’s as well – and there are simply too many to mention without leaving someone important out. Suffice it to say, bettors haven’t had any significant new sources of data for the last 2 decades. Yet we expect gamblers to continue to play despite higher takeout, smaller fields, fewer starts per horse, etc.?
Trakus has recently made some inroads with their advanced timing technologies including ‘distance traveled’ and fractional times to the hundredths of a second, but still we are just scratching the surface of what can be done. The Trakus task is achieved by a small chip placed inside each saddlecloth, that’s it. Equipment placed around the track is also necessary for the system to operate, and that ain’t cheap. But my solution is quite inexpensive.
In order to increase handle, both from whales and from new players, the industry needs another innovation in handicapping data/analysis – physiological information gleaned from the horse itself during competition. This can be accomplished with a simple on-board heart rate monitor, and the past few years have seen many innovations as chronicled on this blog. Up next are some units that leverage infra-red technology to analyze the oxygen content of the muscles, and/or characteristics of the horse’s blood during races. Heck, one system will transmit that data in real-time to your I-Phone or I-Pad. Amazing. This gear will contribute reams of data for owners, trainers, and bettors to consider when going to the racetrack. And it may just well shut up PETA next time they set their sights on our wonderful sport – as we will become the first major sport to monitor physiological vital signs DURING actual competition.
Why hasn’t someone thought of this before? Well, they have – sort of, check out these guys:
I’ve been watching this group for years, but their efforts seemed to have stalled. I think they make their deductions based strictly on high-speed video analysis, but I am not positive. Case The Race was founded by Dr. Gary Knapp, breeder of Big Brown, and I intend on reaching out to him this week as we both seem to be on the same wavelength.
Granted, 99% of horseplayers will have no idea what to do with these numbers and that’s the point; the race will then be on to become conversant in terms such as stride length, VO2max, lactate threshold, recovery heart rate, etc. Early adopters will get an edge – and that is what every gambler is after.
Once Beyer Speed Figures became part of the DRF past performances, their value soon eroded. The right racing circuit can attract significant new business being the first to provide this data stream. I doubt the US will lead the charge in this regard. Perhaps Australia? Two major HR/GPS systems originate in Perth. Hong Kong? Already the HKJC provides the most in depth past performance analysis:
Although the focus of this blog has been using this data to help trainers condition their horses; I will now turn my focus towards using these tools as a way to evaluate a horse’s racing performance. This is probably a multi-year project, so I better get started this week…wish me luck.
Any feedback is always welcome via blog comments below.
Adding yet another dimension to understanding your horse’s performance, Etrakka has formally introduced the metric known as SL50 – stride length at 50kmh (31mph, or 14.8sec/furlong). The new GPS antenna also will allow you to view stride length at peak speed; something that is becoming ever more common at 2yo in training sales.
To date: several hundred measurements of SL50 have been taken ranging from 18-23ft, with the average score sitting right at 20 feet. As expected, elite horses average readings come in at just over 21.3 feet. How do your horses measure up?
This link takes you to some info from the manufacturer; including a neat comparison between 2 horses with identical HR/GPS responses to exercise – however a superior stride length made one a millionaire:
Some barns are looking for reasons to keep a handsome, well bred young colt – and yet others are looking to cull stock. Stride length can provide a valuable piece of information when making those difficult choices.
Bringing along some youngsters and hoping to avoid downtime due to shin soreness? Checking these figures during each workout is crucial – as you can catch the very first instance of a shortening of stride – as little as 1.5 feet, that can be one of the very first signs of problems. Perhaps you are then looking at 2 weeks of rest, as opposed to 2 months-
A while back someone had posted this link on my Facebook page about Stride Angle:
The great Secretariat was thought to have a stride length at peak speed of just over 25 feet, which may be larger than all the greats save Man O War – however the link above shows him to have a very large stride angle (110 degrees). Conversely, Seattle Slew had a small stride angle of just 88 degrees.
While some of the measurements featured here could be open to debate, the main point is that when you increase stride angle by 1 degree you improve stride length by 2%. Think shoeing, think massage work, think uphill gallops – all ways to increase power and range of motion – leading to an improved stride length – the Etrakka can help you quantify and analyze this variable during your conditioning regimens. Find out what is, and isn’t, working.
Save time. Save money. Win races.
2013 has been an exciting time for new HR/GPS technology, and here comes a solution tied into the I-phone App craze. I’ve had one famous US trainer, a household name with big time stock, ask me when he could stand trackside with his I-pad and get real-time HR/GPS data on his training horses, and ClockItEQ promises to fill that desire.
In my job, teaching trainers how to use equipment remotely, and send me the results via email, has been frustrating on its best days. Unless they are heavily invested, both financially and intellectually, in the concepts of HR/GPS monitoring and exercise physiology, the task can prove too time-consuming for a busy stable. Integration of the gear into a training program along with timely transfer of data to me here in Kentucky is the goal. Enter ClockItEQ.
I’ve already downloaded the free App onto my I-pad and I-phone, and this morning ordered my I-phone 4S compatible strap. If you have an earlier version of an Iphone, there is a small ANT+ antenna to purchase as well. Total startup cost under US$200, and the product ships from Australia.
Here are some screenshots:
This is how I understand the workflow:
- Jock/rider downloads Jockey App onto his I-phone. (Or trainer gives his to rider).
- App is started, and zipped up into any pocket, rider doesn’t need access.
- Compatible HR strap is affixed to horse, under girth.
- During workout, data is recorded and transmitted to Trainer’s App-enabled Iphone/Ipad trackside. If headsets are employed, trainer can communicate desires to rider up.
- Afterwards, data is stored online for further sharing/analysis.
The solution uses the built-in GPS common to modern I-phones. Genius. Thus far, in order to setup any track, you have to walk to each timing pole with your phone. Remote set-up via Google Earth is around the corner, I am told. Each workout session within the App incurs a fee. There is volume pricing available, and current costs are under $2 per session. Thus far, no Android version is available.
I’ll report back later with my experiences here locally. Anyone else out there want to give it a shot? – I’ll be glad to help at NO COST. My goals are evolving a bit; these days I find myself with images of a racing jurisdiction (perhaps Hong Kong) where all trainees and race entries are required to wear HR/GPS gear, and data is recorded/analyzed much like Past Performances – but adding the all-important dimension of heart rate/level of aerobic effort/recovery. Owners/trainers benefit, as well as handicappers and track ownership.
A guy can dream, right?

Many casual horseplayers don’t even realize that she just won the G1 Delaware Handicap over 10F on a fast dirt surface during the high humidity of an East Coast summer, without the ‘benefit’ of a pre-race Lasix injection. I, too, am guilty of no longer combing the racing form for that missing ‘L’ designation – I’m just used to seeing it 99% of the time in all the big events.
So, what happened?
Well she won handily as expected, even coming off a disappointing effort at Churchill Downs in her last race (on Lasix). Through her now 20 race career she has run without the drug thrice, this past weekend and a few times in Dubai. She has run both well and poorly with and without the drug. Scuttlebutt is that Royal Delta didn’t fare too well after her recent CD defeat, behaving poorly and perhaps listlessly – pretty much the same reaction that Life at Ten gave us in the Breeders Cup a few years back. To Mr. Mott’s credit, he gave her A shot (without THE shot) in Delaware this weekend.
Much further away from the spotlight; one of the 2yo I have worked with in Camden, SC over this past winter recently romped in her second Lasix-less start:
That’s a 12+ length win in a dirt 5F sprint in hot and humid Iowa, again with no Lasix. She made her first start over turf at Colonial Downs last month and disappointed – so congratulations are due to the connections for keeping with the ‘no unnecessary medication’ plan, even though she’s been claimed away and is likely to run with the drug next time out. Will she improve further due to the FTL, or first time Lasix, angle? My gut says no.
Now we are left with the 2 camps: one who says ‘see, it’s not a performance enhancer’; and the other who says ‘see, most horses don’t need it and can still run well’. Who to believe?
Just twice this past week in the world of sports I have come across the issues of diuretic use. First, I read a fascinating book by cyclist Tyler Hamilton called The Secret Race. Essentially this is the closed door testimony that gave the proper authorities the confidence that Lance Armstrong was dirty. But of most interest were the concepts of blood doping and/or EPO use.
At some point, cycling authorities set a benchmark for an appropriate concentration of red blood cells (RBCs) in the bloodstream: 50%. That leaves the other 50% for plasma (water). Kind of sounds like permissible levels of medication in horses. More specifically, there is a threshold for TCO2 concentrations in the equine blood as well – I think 37 mmol. (Just as in cycling it’s not the administration of a banned substance that is being tested for – but the effects in the bloodstream.)
Therefore a higher concentration of RBCs in the blood of a cyclist, which also means a lower concentration of water/plasma – has been repeatedly tied to improved performance. Therefore, cyclists would take EPO to bump up this number towards the threshold of 50, and if too close – would guzzle water and take IV fluids to get in under the threshold. Conclusion: anything that lessens the water component of blood will necessarily increase RBC concentrations and is a performance enhancer. Lasix qualifies.
Secondly, a wave of Jamaican track sprinters have also been recently suspended due to diuretic use. The athletes compete in 100-200m events, are both male and female, and the drug concerned is also considered a masking agent by WADA – meaning the diuretic effect, in addition to being performance enhancing, is also a potential cover-up of other drug use. Agenda-driven equine veterinarians swear this is not the case in their industry. Of course not.
This jibes with my feelings on the subject: weight loss via Lasix is a performance enhancer during the relatively brief event lengths of US horseracing: 50-120 seconds. However the hours of post-race recovery probably aren’t too pleasant for many, and repeated episodes of dehydration over the years likely shorten careers and increase unsoundness.
From what I read; Royal Delta is likely to make her next start without Lasix. Kudos to Mr. Mott – perhaps some of his other stable superstars will try it in the future?
