ATW Dorney Duathlon - March

About this event

Set at Dorney Lake, the Olympic rowing venue west of London, this duathlon offers three distances on completely flat, closed roads — making it ideal for chasing times without traffic concerns. The course features a multi-lap format where runners tackle 5km loops and cyclists spin around the lake on smooth tarmac. The sprint (26.5km total) and super sprint (15km) suit those testing the duathlon format, while the standard distance (53km) challenges seasoned athletes. Spectators can watch from the lakeside café as participants circle through transition multiple times, and clear course marking with regular distance flags keeps everyone on track throughout.
