Steall Ultra 50K
The Steall Ultra 50K is a mountain trail race that traverses the full length of the Mamores ridge and links five Munro summits. The route runs from Kinlochleven across mixed terrain to a finish at the Nevis Range, covering approximately 47 km with about 3,100 m of ascent.
After a start through Kinlochleven the course climbs An Cumham and reaches summits such as Sgòr Eilde Beag, then follows a mix of technical rocky ground, grassy trails and runnable ridgelines to Mullach nan Coirean. Runners descend into Glen Nevis, join forestry tracks towards the Ben Nevis visitor area, then follow the Ben Nevis tourist path beneath the north face and descend via Leanachan Forest and the lower Blue Doon trail to Nevis Range.
The course is fully waymarked and marshalled. A GPS tracker is issued at registration and must remain attached for safety and live tracking. One well stocked support point is located in Glen Nevis at about 31 km and offers drinks, sandwiches and snacks including vegan and gluten free options, plus toilets.
Participants must carry mandatory kit as listed in the event checklist, including a survival bag, and should have a secondary navigation system. Recommended prior experience is completion of a trail marathon with similar ascent. Entrants must be 18 or older. The race contributes to UTMB index rankings and is worth 3 ITRA points.
