A study completed by the Royal Veterinary College has shown that the amount of training steeplechase horses undergo significantly increases the chance of them suffering from exercise-induced pulmonary hemorrhage (EIPH). EIPH is most frequently seen in Thoroughbred and Standardbred racehorses, and can cause significant performance issues.

The exact cause of the condition is unknown, though some believe it's a result of pulmonary capillary stress failure. This occurs when the blood-gas barrier in the alveoli is broken during intense exercise.

Drs. Tegan McGilvray and Jacqueline Cardwell used 177 racehorses in the British National Hunt to test for the prevalence of EIPH using a tracheobronchoscopy and a tracheal wash. In addition to blood, the researchers tested for the presence of hemosiderophages, which are cells that indicate previous lung bleeding.

Tracheal blood was found in 26 percent of the horses, hemosiderophages in 94 percent of the horses) and “significant” hemosiderophages in 78 percent of the horses.

The team drew these conclusions:

Each year in training increased the chances of tracheal blood and the presence of hemosiderophages by 1.5 percent.
Male horses had 85 percent less of a chance of bleeding than female horses
Tracheal blood was twice as likely to be see in winter and spring than in the fall
Horses with significant hemosiderophages were five times more likely to tracheal blood
Horses completing high-impact work were 60 times more likely to have tracheal blood

The researchers' findings support the capillary stress failure theory. Increased time in training causes “cumulative remodeling of the pulmonary vasculature, increasing susceptibility to EIPH through capillary stress failure with ongoing training.”

They note that EIPH may not be avoidable, but identifying horses at risk of the condition will be helpful in determining preventative measures in the future.

The last time C Z Rocket ran at Oaklawn, the gelding was on a 10-race losing streak and in for a $40,000 claiming price.

C Z Rocket may have lost again last April, but Southern California-based trainer Peter Miller and owner Tom Kagele won big after claiming the gelding out of his fifth-place finish.

C Z Rocket captured his next five starts before his streak was snapped with a runner-up finish behind Whitmore in the $2 million Breeders' Cup Sprint (G1) Nov. 7 at Keeneland. Flip the results of the 6-furlong race and C Z Rocket would have gone from claimer to champion in roughly six months.

“My owner actually picked him,” Miller said Wednesday afternoon. “I OK'd it, but he picked him. He was off form, but obviously he had back class and back fast figures, fast sheet numbers. That was kind of what Tom Kagele saw and I agreed.”

Miller, who didn't have to shake for C Z Rocket, said the gelding bled the day he was claimed and “just assumed he was a bad bleeder and we were able to control that.”

C Z Rocket went on to set a 6 ½-furlong track record (1:15) in a July 12 allowance race at Keeneland and edge Flagstaff in the $150,000 Pat O'Brien Stakes (G2) Aug. 29 at Del Mar and $200,000 Santa Anita Sprint Championship (G2) Sept. 27 at Santa Anita before being beaten 3 ¼ lengths by Whitmore in the Breeders' Cup Sprint.

C Z Rocket returns to Oaklawn, this time for a rematch with Whitmore in Saturday's $200,000 Hot Springs Stakes for older sprinters. Like Whitmore, the country's champion male sprinter of 2020, the Hot Springs will mark C Z Rocket's first start since the Breeders' Cup. The 7-year-old son of City Zip has recorded a series of workouts at San Luis Rey Downs in Southern California in advance of the Hot Springs, which also drew Flagstaff.

“The fact that we could run on Lasix was a major factor in us choosing to go to Oaklawn,” Miller said.

C Z Rocket's career U-turn has him poised to reach $1 million career earnings this year. The gelding boasts a 9-2-2 mark from 23 lifetime starts and earnings of $891,641. Prominent North Little Rock, Ark., businessman Frank Fletcher purchased C Z Rocket for a sale-record $800,000 at the 2016 Ocala Breeders' Sales Company June Sale of 2-year-olds. C Z Rocket won his first three career starts (2017) and the $75,000 Kelly's Landing Overnight Stakes (2018) before he began running for a tag last spring at Oaklawn.

C Z Rocket will be reunited Saturday with Florent Geroux, who was aboard for two of the gelding's five consecutive victories last year. C Z Rocket is the 2-1 second choice in the program for the 6-furlong Hot Springs. Whitmore, who has won the Hot Springs a record four consecutive years, is the 8-5 favorite. Whitmore and C Z Rocket are scheduled to break from posts 6 and 7, respectively, in the projected seven-horse field.

“We felt like we could have won the Breeders' Cup if we had a better trip,” Miller said. “We were plus-40 or 50 feet in the race, even though we broke from the 2 hole and he (Whitmore) broke from the (7) hole. Don't ask me how that happened going three-quarters. But somehow or another we ended up giving up 40 or 50 feet in ground and we were closer to the pace than he really likes to be when the pace is that fast. We're excited. Obviously, our end goal would be the Breeders' Cup, but we're looking forward to the rematch.”

C Z Rocket now races for Kagele, Madaket Stables LLC (Sol Kumin) and Gary Barber.

The Hot Springs is the final major local prep for the $500,000 Count Fleet Sprint Handicap (G3) April 10. Whitmore has won the Count Fleet a record three times (2017, 2018 and 2020).
