About

The Stanford 100 Miler 2025 is brought to you by the organisers of The Tanqua Kuru Bicycle Race.

Route

The Stanford 100 Miler 2015 rewards riders who are strong but smart, saving a bit of energy for the tricky final sections.

After a short, easy start out of the village, riders head south along smooth gravel roads beside the Uilkraals River. Clay-hardpack dominates here, so keep your line steady as you zig-zag along.

Turning north, the real challenge begins. The roads remain mostly smooth gravel, but bumps and wet clay sections demand care. Push too hard downhill, and a crash could be just around the corner.

Once over the last climb, it’s time for a final burst of power to the finish line, where cheering supporters await to celebrate your ride.

Tally-ho! The adventure is yours.
