Val d'Aran by UTMB is a trail ultramarathon scheduled for 7–11 July 2027 in Vielha, Val d'Aran, Spain. TrailSplits currently includes 3 mapped courses for this event, with course maps, elevation profiles, weather context, and pacing tools for the uploaded GPX data.
How to get a place: For 2027 the flagship VDA 163K and CDH 110K stay on direct registration (UTMB Index holders from 7 October, everyone from 9 October 2026, while places last).

The organizer lists CDH 110K at 110 km and +6,400 m for 2027; the course file mapped here (the organizer's 2026 file) measures 108.7 km. Small differences come from how each figure was measured; plans and pacing here use the mapped file. Organizer's race list, checked Wednesday 30 September 2026.
