The Yu Man Race Half Marathon is a September trail race held in Haarle, a village in Overijssel, Netherlands. The race takes place in the forests of Hellendoorn, offering participants two distance options: a 10 km quarter-marathon or the full 21 km half marathon.
The course follows unpaved forest paths through the Sallandse Heuvelrug woodlands. It emphasizes steady trail running rather than mud pits or climbing walls. This event is not an obstacle run; participants choose it for a natural course without constructed obstacles, whether they opt for the shorter off-road race or the half marathon on forest terrain.
