Cheltenham Festival-Winning Jockey Tom O'Brien Dies Aged 39

Tom O'Brien, a jockey who rode multiple Grade One winners and earned a place in Cheltenham Festival history, has died at the age of 39.

Grade One is the highest level of jump racing, and riders who win at the Festival are known across the sport. O'Brien's record on the biggest days of the National Hunt calendar made him a familiar name to trainers, owners and racegoers who followed the code closely.

Dying at 39 is a loss that will be felt well beyond the weighing room, among the stable staff, fellow riders and supporters who watched him compete at the highest level.

Details of the circumstances had not been confirmed at the time of writing. This story will be updated as more information becomes available.
