Sprint

The Sprint distance suits athletes seeking a genuine test in an extraordinary setting: a swim where technique counts, a bike where fitness counts, and a run where mental toughness counts. The course takes in the Palace grounds, the Great Lake and the Cotswolds terrain beyond, fully marshalled with aid stations and medical support throughout.

Early June brings mild conditions and long daylight hours, with the grounds at their most beautiful. Racing takes place on both the Saturday and Sunday, individually or as part of a relay team. Spots are filling fast. Secure yours today.

Super Sprint

The Super Sprint is the perfect starting point: a shorter, accessible yet rewarding course. Wave starts keep the swim uncrowded, the bike route is closed to traffic and well-marked, and the run carries you home on the energy of fellow athletes and the Palace grounds.

Early June brings mild Cotswolds temperatures: expect 13-20°C, with lake water around 16-19°C, so bring a wetsuit. Morning starts keep the bike leg cool. Finishers are welcome to stay on afterwards: refuel, then wander the historic gardens at your own pace. This is not a race against the clock; it is a finish at Blenheim Palace.
