Marlow Triathlon
The Marlow Triathlon takes place at Higginson Park in Marlow on 24 May 2026. The event is held in support of Macmillan Cancer Support and is organised by RunThrough.
All races begin with an open-water swim in the River Thames, continue with bike routes through the Chiltern countryside, and finish with a run on grassy terrain in Higginson Park. The event uses closed roads for the bike courses and includes an event village with food and drink options and race marshals to guide athletes.
Three distance formats are offered:
- Half Iron: Swim 1.9 km; Bike 93 km; Run 20 km
- Olympic: Swim 1.5 km (2 laps); Bike 43 km; Run 10 km
- Sprint: Swim 750 m; Bike 23 km; Run 5 km
Entries include a themed medal, free race photos, chip-timed results, and post race goodies. The organiser notes that sustainability is a growing focus in event planning and has carried out research into participant priorities. The event village provides services and partner giveaways at the finish area. Visit the organization's website for the most recent information.
