Bronane Opp is a gravel-road hill race in Singusdal, Vestfold og Telemark, held in September. The main race covers 6 km from Singusdal school to the telecommunications mast on Bronane, with competitive classes for youth, juniors, seniors, and veterans.
The course includes one relatively flat kilometer before the ascent begins, followed by 5 km uphill with 500 meters of elevation gain. Participants seeking a non-competitive option can select a 6 km trim walk or a shorter 3.5 km walking route starting at Omland Farm.
