Show jumper Tim Stockdale is training 12 celebrities in time for a nine-day live competition on BBC1 (7-15 July).

Radio One presenter Sara Cox, Olympic gold medallist Sally Gunnell and American comedienne Ruby Wax are among the celebs who will jump in front of equestrian expert judges. The nightly TV show, Only Fools on Horses, is in aid of Sport Relief.

Qualified BHS instructor Tim Stockdale will train the contestants and select their horses, which include some Grade A jumpers, sourced from all over the UK. The celebrities will be installed at an intensive riding academy for the next two weeks, in preparation for the early-evening BBC1 show.

A team of trainers is supporting Tim, including show jumpers Mia Korenika and Fred Bergendorff, with flatwork instruction provided by dressage experts Jenny Ward and Mary-Anne Trevor- Roper. The contest will take place at Unex Towerlands in Essex, with presenters and judges yet to be confirmed.
One contestant will be voted out each night, with a select few making it to the final, on Saturday, 15 July.
