Frank Hayes had never won a race before and in fact by profession was not actually a jockey
He was infect horse trainer and longtime stableman. Hayes’ death was not discovered until Miss Frayling and race officials came to congratulate him shortly after the race. It was suggested that the fatal heart attack may have been brought on by Hayes’ extreme efforts to meet the weight requirements, possibly followed by the excitement of riding to the front of the pack.
The newspaper reported he had slimmed down from 142 pounds to 130 pounds in a very short time.

Hayes apparently died somewhere in the middle of the race, but his body remained in the saddle throughout. Sweet Kiss eventually crossed the finish line, winning by a head with Hayes technically still atop her back, making him the first, and thus far only, jockey known to have won a race after death.
The horse was never in a race again. It was claimed that Sweet Kiss was nicknamed “Sweet Kiss of Death” for the rest of her life.
