Grafham Water Duathlon & Trail Run – 7th November 2021

Grafham Water Duathlon
& 10K Trail Run


No matter if you are an experienced athlete looking for a fast race, or you are a novice competitor looking for a safe and friendly venue for your first run-bike-run or trail run event, then Grafham Water is ideal. We guarantee you’ll enjoy this fantastic venue that has been used for both national championships and GB qualifier races.

The duathlon starts with an out and back run along the scenic footpaths that follow the South side of the reservoir. After a quick transition to the bike, you’ll head out on a gently rolling bike ride to St Neots before turning at a roundabout and heading back to Grafham Water. The only hill of note on the course, approximately 7% for 500m, occurs just before arriving back at transition. The Standard distance will complete two laps of the bike, after turning in the village of Perry and heading back to St Neots.

Upon completion of the bike leg the second run will repeat the route of the first run, but for only half the distance (phew!).
Those who have paced the event well will be feeling strong as they take the finish line back at the Perry car park.

The Trail runners will start alongside the Standard distance athletes and complete the 10km out and back route.

Many people are understandably nervous regarding entering events again and we want to assure you that we take every measure we can to organise a safe, socially distanced event. To see this in action watch our video Covid-19 Safety at ActiveTrainingWorld Running and Triathlon Events.
