Overview

The Lochalsh Dirty 30mi is a 48-kilometer trail race that last took place in 2019, with its next edition scheduled for June 6, 2026. This 50k event has a bigger field than 70% of its 2649 peers.

The course features 850 meters of elevation gain, which at 17.7 meters of climb per kilometer makes it a hillier race than many 50k events. The £45 entry fee is for a race that loops from Glenelg, passing landmarks before climbing over hills and past ancient brochs.
