Course & challenge

MUT 100 by UTMB

The course starts with the old Voortrekker Pass, also called Cradock Pass, the biggest climb of the route, then drops into the Pass to Pass route and crosses the Outeniquas into Champherskloof and the fynbos and heat of the Klein Karoo. After Montagu Pass and a lunch stop comes the Dizzy Heights climb and mountain running with views down to George Dam.

From there the route crosses the Kaaimans River to Groenkop Nature Reserve, follows the Groeneweide Trails out of indigenous forest to the Saasveld aid station, and runs along the Garden Route Dam to Tierkop, where it rejoins the 60 km route for the Wall and Tonnelbos. The last kilometres pass the Trail Kiosk cheering point and run under the city’s bridges to the finish. Expect big climbs, rocky trails and technical descents, with runnable sections between. Finishers earn 3 Running Stones. Cut-offs are not yet published.

A 05:00 start and a 25-hour limit make a long day for the people waiting in George. On Livebib the runner shares a link to their own broadcast, opened in a browser with no app or account: where they are on the course line, how far they have come and a finish estimate that updates with their pace, so the people waiting know when to be at the Trail Kiosk. When signal drops in the forest, the position is carried forward along the course and marked estimated. The runner chooses who gets the link.
