Grand National winner Graham Lee switches to Flat racing Lee rode 995 winners domestically including five at the Cheltenham Festival, but his career has been punctuated by serious injury, most notably fractures of a leg, an arm and, this season, a collar bone and, most recently, a dislocated hip sustained in a fall at Southwell on Feb 15. While increasing weight is a common factor in bringing about the retirement of many jump jockeys, it is the opposite problem, a lack of weight, which has persuaded Lee to give Flat racing a serious go. He rode as an apprentice on the Flat before switching to jump racing. If it went well on the Flat I could extend my career another 10 years and, though I'd never say never, I've probably had my last ride over jumps. I told Ferdy Murphy [for whom he was stable jockey] on Sunday and he was very supportive, so I will have a go and see what happens. Top of the jockeys currently carving out a successful career on the Flat after riding over jumps is Jim Crowley, stable jockey to Ralph Beckett. No jockey has won both the Grand National and Derby, but it is not a completely fanciful notion. Ray Cochrane, albeit somewhat younger, switched from jump to the Flat after breaking his leg and having the same problem; being too light. He won the Derby on Kahyasi in 1988.
