This Sunday heralds the return of one of the UK's most prestigious endurance triathlons; Ironman UK. This is the only officially branded Iron distance event in England. More than 1,500 triathletes will be speeding through Lancashire's countryside as they tick off a tough 2.4 mile swim, 112 mile bike and 26.2 mile run.
Competition will be fierce for the 50 age group slots for the 2011 Ironman World Championships in Kona, Hawaii, up for grabs. Returning to Bolton for its third year, the revised route promises a more spectator-friendly circuit as it winds through Bolton town centre. Crowd support of more than 30,000 people is expected.
Will it be shown on TV?
Ironman UK will be broadcast on Channel 4 at 7am on August 21. Set your alarm or press the record button and enjoy catching up with the highlights from the comfort of your sofa.
Any elites taking part?
Of course! Representing the UK in the men's race we have Nick Saunders, Paul Hawkins, Oliver Simon, Stephen Bayliss (depending on when his pregnant wife Bella, also a triathlete, gives birth) and Toby Radciffe, who has been giving weekly tips in our TW Triathlon Training Newsletter. Yvette Grice and Joanna Caritt will be taking up the mantle for British women.
