The Half Triathlon distance features a shorter swim leg, while offering the same thrilling experience of crossing Lake Iseo in the middle of the night.
The 145 km cycling course, with 2,790 m of elevation gain, follows the same route as the Xtrem distance up to Ponte di Legno, tackling the legendary Aprica and Mortirolo passes without taking on the Gavia Pass.
The 22 km run course, highly undulating and featuring 850 m of elevation gain, winds through the area around Ponte di Legno and along the valley floor. The route passes through the hamlets of Zoanno, Precasaglio and Villa Dalegno, then crosses to the opposite side of the valley through the centre of Temù. From here it climbs to the Valbione area (1,500 m a.s.l.) before descending back to Ponte di Legno, where the finish line is located.
The start is located in Predore, on the opposite shore from Iseo. Athletes will complete a 2.8 km lake crossing to Iseo, where the first transition area, T1, is located.
Competitors will experience the same adrenaline as the Xtrem Triathlon, with nighttime boat transport and a start at first light of dawn. The swim exit point is marked by a powerful beacon pointing skyward.
