Wimbleball Lake Triathlon
The Wimbleball Lake Triathlon takes place at Wimbleball Lake near Dulverton, Somerset. This venue has a history of hosting endurance events, having previously served as the location for Ironman 70.3 for a decade. The 2026 edition introduces a full iron distance triathlon for the first time at this site.
Participants begin with a swim in the lake, a location where public swimming is typically not permitted. The cycling portion follows on quiet local roads described as having a rolling or undulating profile. The final run section consists of a 10.5 km course which participants complete for a set number of laps depending on their chosen distance.
Available event categories include:
- Iron Distance Triathlon: 3800m swim, 174km bike, and 42km run.
- 70.3 Distance Triathlon: 1900m swim, 92km bike, and 21km run.
- Standard Triathlon: 1500m swim, 45k bike, and 10k run.
