Triathlon Sprint del Lago di Chiusi

The Triathlon Sprint del Lago di Chiusi begins with a 750-meter swim in Lake Chiusi, followed by a 20-kilometer bike ride and a 5-kilometer run. This sprint-distance triathlon takes place on the Tuscan side of the Siena area, utilizing the lake shore and the town of Chiusi. Having reached at least its tenth edition, the event is established, maintaining a straightforward format: swim, ride, run, all over short distances suitable for fast racers and newer triathletes. The bike course follows the Sentiero della Bonifica and enters the historic center of Chiusi, combining flat path riding with a town section. The run is set entirely on the Sentiero della Bonifica, a straight, practical route noted by athletes for its speed. A previous edition attracted around 150 participants and was organized by the Siena fire brigade with Il Gregge Ribelle, contributing to a strong local-club atmosphere rather than a large-scale city event.
