Julio Felix was born in New York on Feb. 6, 1967, while his father was stationed there during his time in the U.S. Army. The family is originally from St. Croix, Virgin Islands, and returned there when Felix was very young. Although Felix had never been around horses, his best friend was a jockey and encouraged him to learn to ride. He started riding when he was about 15 years old. Felix rode a few races in the Virgin Islands over the course of a year and then went back to high school to earn his diploma. He moved to Miami in 1989 and secured his first win in the United States at Calder Race Course that year. A successful run in Florida was interrupted by a fractured leg, and the time away affected his business there. A trainer friend suggested he start anew at Thistledown, and many of his successes came during the 14 years he was based in Cleveland. He holds six meet titles from Thistledown beginning in 1992 and twice, in 1992 and 1994, was the track's leading rider for the full year. Among Felix's stakes scores is one graded event, the 1994 Sabin Handicap (G3) at Gulfstream Park with Hunzinga. Other memorable mounts across his career include Lady Cherie, with whom he won 13 stakes, and multiple stakes winners Ifufeelfroggyleap, Down Thepike Mike, Buckys Brat, and Sister Milly. He rode the 2,500th win of his career when he scored with J. Pa at Turfway Park in February 2012. His cousin is jockey Victor Lebron.
