Great Glen Ultra Marathon 42

The Great Glen Ultra Marathon 42 is a solo foot race following the Great Glen Way between Fort Augustus and Inverness. The course covers a distance of 42 miles with approximately 6,000 feet of total elevation gain. Participants traverse the High Route section of the trail, which provides views of Loch Ness and the surrounding hills and mountains. The entire route is marked with official waymarks and arrow signs.

The event is designed as an unsupported race. Participants are required to provide three drop bags, which the organizers transport to specific checkpoints along the route. These checkpoints are located at Invermoriston, Drumnadrochit, and Abriachan. While the race is self-sufficient, spectators are permitted to meet runners at the Invermoriston and Drumnadrochit checkpoints, as well as the finish line. Spectating is strictly prohibited at the Abriachan location.

The race begins at Fort Augustus Village Hall and concludes at the Inverness Sports Centre. The final section of the course includes a lap of the 400 meter athletics track at the stadium. There is a 15 hour time limit to complete the distance. Runners register at the sports centre in Inverness before being transported to the starting line by a provided bus service.

Mandatory safety equipment must be carried for the duration of the event, including a foil blanket, a mobile phone, and the capacity to carry at least one liter of water. The use of walking poles and the participation of dogs are not permitted. While there are no formal entry requirements, participants are expected to be capable of completing the distance and elevation. Visit the organization's website for the most recent information.
