About the race
The Utrechtse Heuvelrug Ultra Trail (UHUT100) is a trail running event in Leersum, Netherlands, held over two days on 29 and 30 May 2027. The event uses GPX routes through the Utrechtse Heuvelrug and offers multiple distance options based on two distinct loops of about 50 kilometres each.
Distances:
- 100 km run combining both loops
- 75 km option using parts of both loops
- 50 km single-loop options (Amerongen and Doorn)
Participants receive a UTMB Index upon finishing any ultra. The event provides aid stations along the route; runners must bring their own race cup because no disposable cups are available. Drop bags are available for the 100 km (halfway) and for the 75 km (after 25 km when returning to basecamp). The organiser is Trail Events and partners include Molecaten Landgoed Ginkelduin, Staatsbosbeheer and Gemeente Utrechtse Heuvelrug. Event capacity is limited to 1,170 participants.
A medal is an optional purchase for this edition; medal dimensions are approximately 9 x 9 cm and can be ordered separately. All participants must carry mandatory safety gear throughout the ultra, including a race cup, a charged mobile phone, a race vest with at least 1 litre of fluid and basic first aid items, an emergency blanket, rain jacket, navigation device and sufficient nutrition for 10–15 km. Navigation may be by watch, handheld device or phone; a power bank is required if the phone is used. Visit the organization's website for the most recent information.
