Even a crack in his front right hoof didn't keep Girvin from training this week for the biggest race of his life.

Girvin, who is starting in the No. 7 post at Saturday's 143rd Kentucky Derby at Churchill Downs, suffered a quarter crack in his right front hoof that was discovered not even two weeks ago. While not serious, it is obviously very painful for a horse to put weight on the injury.

What did trainer Joe Sharp do to make sure his Throughbred was ready for the first leg of the Triple Crown? He put him in a pool and had him do his cardio.

Girvin swam in the pool three times to stay fit and received other remedies such as treatment with a fiber glass patch and a special horseshoe, according to 11Alive partner USA TODAY Sports. He returned the sloppy track on Thursday, and Sharp told USA TODAY Girvin is as ready as ever for Saturday.

“Every day it just gets better and better,” Sharp said. “As his trainer, being around him every day, we wouldn’t run him if we didn’t think he had a shot to run a winning race. I don’t think his effort here will be hindered.”

Girvin's odds of winning as of Saturday afternoon are 22-1. The colt was the winner of the Louisiana Derby last month and is 3-of-4 in his career.
