Classic-winning jockey Jason Weaver has announced his retirement citing weight problems as a major reason for his decision to quit.
Weaver, who for the past few years has ridden at around 8st 9lb, has no immediate plans for the future but is hoping to stay in racing.
"The weight has become a problem," he said.
"Obviously that's a bit scary to suddenly say it's finished but I'm only 30 - still young - so I said let's give it a go. I only made the decision four or five days ago.
"There have been plenty of highs. I've had a great time and racing has been very, very good to me. I just feel that the time is right for a change of direction.
Weaver rode more than 1,000 winners worldwide in a career spanning 14 years.
He is one of only seven jockeys to have ridden 200 winners in a season. He achieved the feat in 1994 when runner-up to Frankie Dettori in the jockeys' championship.
Weaver had earlier that year won the 2000 Guineas on the Mark Johnston-trained Mister Baileys.
The jockey went on to record another seven Group One victories.
Weaver started his career as a 16-year-old with Luca Cumani and became champion apprentice in 1993 with 60 winners.
He then moved north to Middleham to become stable jockey to Johnston.
Johnston and Weaver teamed up to take the 1995 Gold Cup with Double Trigger and they returned to Royal Ascot 12 months later to land the St James's Palace Stakes with Bijou D'Inde.
Weaver, who rides out for Giles Bravery, will continue to help out at the trainer's Newmarket stable.
