Marlow Triathlon at Higginson Park

The Marlow Triathlon takes place at Higginson Park in Marlow on 24 May 2026 and is presented as the debut edition. The event is held in support of Macmillan Cancer Support, with Macmillan listed as the RunThrough triathlon partner for 2026.

The event offers three race distances:

  • Half Iron: Swim 1.9 km, Bike 86 km, Run 20 km
  • Olympic: Swim 1.5 km (2 laps), Bike 38 km, Run 10 km
  • Sprint: Swim 750 m, Bike 23 km, Run 5 km

Each race begins with an open-water swim in the River Thames, includes cycling routes through the Chiltern countryside, and finishes with a run on grassy terrain in Higginson Park. The event description notes closed roads on the bike routes, a riverside start, and an on-site event village. RunThrough provides marshals to guide athletes around the course.

Entries include a unique themed medal, free race photos, chip-timed results, and post race goodies. The event village will offer food and drink options and partner provided items at the finish. Sustainability is mentioned as an area of focus for the organiser. Visit the organization's website for the most recent information.
