About the race
The OMM is a self-reliant, two day mountain navigation event taking place in Talnotry, Scotland on 24 to 25 October 2026. Competitors enter as teams (typically two, with an option for teams of three) and carry all kit for an overnight campsite at the halfway point. Each day teams receive a new map and must plan routes to visit checkpoints; linear courses require visiting controls in order, while score courses let teams choose which controls to visit within a time allowance.
Linear course example distances (straight line):
- Elite: Day 1 47 km, Day 2 38 km
- A Course: Day 1 36 km, Day 2 29 km
- B Course: Day 1 25 km, Day 2 20 km
Score course time allowances vary by length (Long, Medium, Short) and are set per day. Navigation is by map and compass only; GPS or mobile devices must not be used for navigation. Teams must remain together, carry mandatory kit and cooking equipment, and sleep in a single tent per team. Mandatory items include waterproof clothing, warm layers, headtorch with long battery life, whistle, compass, the supplied map, insulated sleeping system, first aid, survival bag, rucksack, emergency rations and water capacity. Trackers and timing tags are issued for safety and must be returned at the event end. The event is volunteer run, organised on a not-for-profit basis, and uses independent ecological assessment for each area. Independent studies estimate the event brings around £500k additional revenue to the local area. Visit the organization's website for the most recent information.
