Overview

The Great Glen Ultra Marathon 72mi in Corpach, United Kingdom, took runners on a 116-kilometer journey through a route mixing canal towpaths, forestry tracks, and road sections. Despite covering low-lying canal corridors, the course packed 8500 meters of elevation gain across its span, demanding an intense 73.3 meters of climbing per kilometer that tested continuous mountain stamina.

The 22-hour time limit required an average pace of 11.4 minutes per kilometer, establishing a cut-off more generous than 64% of 100k peers and tighter than 36%. That cushion gave runners breathing room to manage the massive elevation profile.

With 29 finishers in 2024, the race featured a field smaller than 55% of 100k events and bigger than 44%, offering an uncrowded trail experience over its 10 editions since 2014.
