The Descente London Duathlon, the world’s biggest run-bike-run event, will take place on Sunday 16th September on closed roads in the beautiful Richmond Park. The event offers athletes of all abilities the chance to race through stunning surroundings whilst competing in a variety of distances. You can choose between a half duathlon, a full duathlon or, if you’re feeling particularly daring, an ultra-duathlon. So whether you’re out to complete your first duathlon or pushing for a personal best, there’s an event for you! We even have a team relay duathlon event so you can split up the legs and take on different teams alongside your friends. Not only that, when you enter the London Duathlon you’ll receive a free Descente cycling jersey worth £130!
