About the Route
This race route traverses the full length of the Mamores range, an iconic mountain ridge, linking 5 Munro summits. After an exciting start, weaving through the streets of Kinlochleven, the route climbs steeply up An Cumham via excellent mountain trails, to overlook Loch Eildhe Mor. A steep climb up a good stalkers path leads up to the first summit on the ridge, Sgor Eilde Beag. From here a mix of technical rocky ground and grassy trails lead across the mountain summits all the way to the western end of the ridge at Mullach nan coirean. A fast runnable ridge then leads the way down into the forest in Glen Nevis before joining forestry tracks leading the Ben Nevis visitor centre and the Aid station. The route now joins the Ben Nevis tourist path, rapidly climbing again to Lochan Meall an t-Suidhe (otherwise known as the ‘Half Way Lochan’), before traversing under the towering north face cliffs of the Ben to the CIC hut. Descending via the main Allt, a ‘Mhuilinn track takes runners towards Leanachan Forest and excellent tracks that eventually connect with the lower section of the Blue Doon MTB downhill track. It is steep and unrelenting, with banked turns leading to an amazing finish at the Nevis Range
