As Keen As Mustard Grafham Swimrun Survivor

This is a solo timed lap swimrun held on 27 September 2026 at Grafham Water Visitor Centre, Marlow Car Park, Buckden Rd, Grafham, Huntingdon PE28 0BH. The event uses a 2.5k lap with a run to the start and finish, two swim sections in Grafham Water and three run sections per lap. Each lap has a total elevation of about 20 m.

Lap times reduce as the event progresses, with the first lap allowed 40 minutes and the permitted time decreasing through subsequent laps to 16 minutes for lap 12. Competitors complete as many laps as they can before the lap cutoffs end their race. There will be one final survivor, the last person remaining on the course.

Splits for each lap are listed as: Run 1 700 m, Swim 1 220 m, Run 2 1000 m, Swim 2 400 m, Run 3 250 m. The course is marked and signed; no navigation skills are required but observational skills are needed. Participants must follow the marked route or face disqualification.

Solo entrants must be 18 years or older and able to swim and run the minimum lap distances. Mandatory personal equipment includes a waterproof packaged small bandage, a whistle, and a soft cup or water bladder; a wetsuit is required if water temperature is below 14 degrees Celsius. Organisers provide race number bands and swimcaps and will conduct random kit checks. Medical staff and an emergency ambulance will be present at Race HQ.
