In 2027 we celebrate the 10th edition of the Cave Triathlon. The Cave Triathlon takes place at the Albert Canal in Kanne, just 6 kilometers from Maastricht. Thanks to the spectacular course, the passages through the unique Caves of Kanne, the rolling bike course, and the lively finish zone, this is one of the most atmospheric triathlons in the Benelux.

Run through the marl caves

UNIQUE EXPERIENCE

Each lap an 800m loop through the caves

The marl quarry of Kanne is one of the most beautiful and authentic limestone quarries, with a total network of passages extending to no less than 16 kilometers. It is a pristine and original underground landscape with high passages, reaching over 8 meters in places. Enjoy the silence (spectators not allowed in the caves) and the coolness (12°).
