A flat and smooth course at the stunning Dorney Lake nestled within 450 acres of parkland makes this a perfect site for a personal best.
The swim portion of the event takes place within the lake, and from here triathletes cycle the lake's perimeter along the tarmac. The final stretch, the run, will consist of an out-and-back along the lakeside.
