Limited to 400 entries this year.

From sunrise to sunset and into the night, your gravel-grinding odyssey from Cullinan to Dunkeld Country Estate will be life-changing. Unspoiled scenery, open gravel roads and a tough 20-km climb to the finish on already-spent legs make this race the toughest of them all. Do you dare?



Cullinan to Tonteldoos MTB Ultra Ascent 2023 will take riders and their support crews over 260km of unmarked district roads.



The race is known for its grueling terrain, with an elevation gain of 3200m over the course of 24 hours.



You will have 24 hours to finish the race. Riders start at sunrise and most riders can expect to finish at around midnight.
