Route information

We’re returning to Higginson Park for the Marlow Triathlon on Sunday 19th July 2026, following the success of our inaugural event earlier this summer.
Swim in the River Thames, cycle through the scenic Chiltern countryside, and finish strong with a riverside run across the park. With stunning views and a well-organised setup, it’s a must-do event to kick off your summer season.
Whether you're taking on your first triathlon or chasing a personal best, this event offers Sprint, Olympic, and Half Iron distances. Each race begins with an open-water swim in the River Thames, followed by scenic bike routes through the rolling Chiltern countryside, and finishes with a run on grassy terrain in the heart of Marlow.
This is your chance to race in one of the most beautiful triathlon locations in the UK. With a riverside start, closed roads, and a buzzing event village, the Marlow Triathlon delivers a memorable challenge for every level of athlete.
