Whaka100 2026

Whaka100 is a mountain bike marathon weekend in Rotorua, New Zealand, where riders race through the Whakarewarewa Forest on singletrack-heavy courses. It is the largest mass-participation MTB event in the Southern Hemisphere, with over 3,000 riders anticipated across six distances. Distances range from a 10km ride for a shorter objective, a 25km option, the popular 50km, the classic 100km Whaka challenge, and the 175km Giant Miler for those seeking the longest day on the bike. The course focuses on Rotorua’s forest trails, particularly the distinctive singletrack that defines the race's mountain-bike character. The participants include not only seasoned endurance riders but also first-timers, regular cyclists, and experienced racers, all able to select a distance suited to their ability. The weekend format is also significant, as Whaka100 is structured around riding, spectators, and the cycling community, rather than a singular start-and-finish point.
