The 100 Miler



The 100 Miler is considered the ultimate challenge in trail running around the world. To achieve a finish in this distance is a feat that only a few trail runners can claim.

In South Africa, the 100 mile distance is relatively new and the Karkloof100 aims to produce a world class event that will cement itself as one of the ultimate endurance challenges in the country.
