The Marlow Classic takes place across the scenic Thames Valley area.
Swim the river, cycle the hilly open roads, or run the flat Thames path – with a mixture of grass, tarmac, and trail – taking in the views of Marlow and the surrounding areas.
Join the Triathlon for the ultimate challenge, or either of our Duathlon/Aquabike categories if you prefer to focus on specific disciplines.
If you only fancy a dip in the Thames, then pick one of our swim-only categories instead and get yourself wet!
With multiple distances for each discipline, you’ll find something to challenge yourself this summer.
