IAU 100 km World Championships

The IAU 100 km World Championships have been held annually since 1987, at different locations, and is organized by the International Association of Ultrarunners (IAU).[1][2] Due to lack of sponsorship, the 2013 event, planned for Jeju Island, South Korea,[3] was cancelled and the 2014 event, originally due to be held at Daugavpils, Latvia, was held instead in Doha, Qatar.
