Conquer The Chilterns Triathlon – July 2025

Join us for a sprint, standard or middle distance triathlon, 5k & 10k on Saturday 12th July 2025. Or if you don’t fancy the full thing, there’s also Aquabikes to select from as well!

Take on a 5k, 10k, Triathlon or Aquabike including a swim in the Thames, a bike around the scenic Henley on Thames and surrounding country lanes, and finish off with a trail run through the woods.

This Triathlon is an exceptional choice for those wanting to take on an open water swim before taking in the stunning views alongside a hilly yet scenic bike course, and an out and back run route through Great wood!
