Joseph O'Brien is looking forward to returning to the saddle for a good cause in the Clipper Logistics Leger Legends Classified Stakes at Doncaster on Wednesday.

O'Brien, 23, retired this year to concentrate on a training career after a long-running battle with his weight, but his riding career, though brief, was highly successful.

Twice champion Irish jockey, he won four British classics, including Leading Light in the St Leger in 2013.

He lines up at Doncaster aboard the George Scott-trained Phosphorescence for the special charity event in aid of Jack Berry House and the Northern Racing College.

"I'm looking forward to it. There's been a bit of banter flying about, all in fun. It's all in a good cause," he said.

"I haven't done anything out of the ordinary, I've been riding out a bit at home, so I shouldn't be too unfit, hopefully.

"I don't know much about the horse I ride. I know he's been off the track for a while. He has some form in the past, so hopefully he can run a good race.

"I love the training, it's keeping me busy."

Gay Kelleway has just returned from supervising her runners at Deauville and has high hopes her mount Hijran can give her a great ride.

She is a regular in these events and was just touched off in this race in 2013.

"I rode in the trainers' race over seven furlongs last week and finished fifth on a mile-and-a-half horse. He ran a corker and another half a furlong, I'd have won," said the Newmarket trainer.

"I spoke to Michael (Appleby, trainer) and they fancy the horse to run a big race. He improves horses and I'm a big fan of his. I've got a nice ride, a nice draw and it's the kind of horse that suits me as he likes being held up.

"I was second on an outsider in this race when I went too soon, but I won't be going too soon on this one. I got beat a nose by a jockey who had recently retired.

"I've been in Deauville and it was a hard month for me because I ride out all the horses over there with my assistant and muck them out as well, which I wouldn't at home. And then I play hard.

"I always lose about 10lb when I go over there. I get myself fit and ride in the trainers' race which puts me right for the Legends race.

"It's all about getting your eye back in. When you haven't ridden for a long time it's about getting your sharpness back. You'll never be as stylish as you were when riding every day, but I'd like to think I'm sharper for my latest outing."
