The Lakesman Triathlons is a critically acclaimed series of endurance events held annually in Keswick, in the heart of England’s Lake District. Centered around the dramatic Derwentwater, the signature Half‑distance (70.3) triathlon features a 1.9 km (1.2 mi) swim, 90 km (56 mi) bike ride, and 21.1 km (13.1 mi) run. Beyond the solo half-triathlon, there are relay options, an Aquabike (swim + bike), and a Bike/Run duathlon, each offering the same routes, athlete hospitality, and red-carpet finish. Since its inception in 2016, Lakesman has grown in prestige—earning Racecheck’s “Best of the Best” global triathlon title in 2024—and now hosts the British & English Middle Distance Championships each June. The event draws around 1,000 athletes annually, offering beginner-friendly courses with flat profiles, spectator-friendly laps, on-course support, and a festival atmosphere in one of the UK’s most scenic regions.
