About the race
The Utrechtse Heuvelrug Ultra Trail Winter is a two day trail running event around Leersum on the Utrechtse Heuvelrug. The full UHUT100 is composed of two loops of approximately 50 km each, run on consecutive days from a base at Molecaten Park Landgoed Ginkelduin in Leersum.
Distances
- 100 km split over two days, two loops of about 50 km
- 50 km Rhenen loop
- 50 km Doorn loop
Each 50 km route is GPX based and navigable on a watch or phone. The organizer provides live tracking via a tracker issued at the race office and three aid stations along each route plus an additional station at the finish. Participants are expected to be self-sufficient for stretches of about 10–15 km. No disposable plastic cups are provided so runners should carry their own cup or bottle; a race cup is available for purchase at the event office if needed.
Finishers of the ultras receive a UTMB index. The event is part of the DUS2026 series of monthly ultras. Practical details note that a medal is not included by default and must be ordered separately, and that participants will receive pre-event information and the GPX file before race weekend.
