Natuurmarathon Tessenderlo 2026

The Tessenderlo Nature Marathon takes place in Belgium’s De Kempen region, beginning at 9:30 AM. Participants can run the full marathon individually or as a relay team of two or four. The course consists of four loops through four nature reserves, with nearly the entire route on forest trails. The elevation gain is listed as 393 meters, indicating it is more than a flat woodland run. Registration is straightforward and affordably priced at 27 EUR for the full marathon or 14 EUR per relay runner. Early participants described it as a pleasant forest run and commended the first edition.
