Triathlon Olimpico No Draft Lago di Brasimone is an Olympic-distance triathlon at Lake Brasimone in the Tuscan-Emilian Apennines, using a no-drafting bike format. Athletes swim one 1,500-meter loop, cycle one 40 km loop, and finish with a flat run consisting of two laps around the lake. The event contributes to the national ranking, attracting competitive age-groupers and athletes who prefer racing the bike leg individually rather than in a pack.
The bike course provides the race's challenge: it is hilly, technical, and features climbs and descents through the Apennine terrain. Following this, the run shifts the pace entirely, with a flat, traffic-free route circling Lake Brasimone twice. Nearly 500 athletes have participated, indicating its appeal to those who favor a true no-draft test over a fast group ride.
