The BBC's Olympic Dreams is following some of Britain's stars as they strive to compete at the 2008 and 2012 Olympics.
Diver Tom Daley, heptathlete Jessica Ennis, Paralympic dressage star Lee Pearson and BMX world champion Shanaze Reade are among those being featured.
After its launch in December, production of the second TV series is now under way, with a return to our screens planned for July.
Series one included the men's coxless rowing four of Andy Triggs-Hodge, Alex Partridge, Peter Reed and Steve Williams. Olympic Dreams followed them for the first shoot of the new series.
