Info/rules/kit list revised 29.9.25 to include info on parking/registration/team amendments

Couple of changes to this year’s format: the solo class has been removed from all courses for safety reasons and instead we are allowing teams of two or three to compete. Teams are also encouraged to join up informally while out on the hill if it helps you get round in one piece safe and sound.

There will also be an opportunity for teams to run a one-day only linear course, including both orienteering and hill sections, on the Saturday if you fancy a taster of the GMC without the camping bit.


Every other year (normally!) GRAMP stage a special kind of 2 day Mountain Marathon called the Grampian Mountain Challenge or GMC for short.

You need some basic orienteering skills as well as the ability to yomp over mountainous terrain in all kinds of weather as both days have two sections: a shorter orienteering section of medium technicality using orienteering maps and a longer hill running section using OS/Harveys or similar maps.

You can run in pairs or teams on a range of courses carrying a small sack with only essential safety/spare kit as we transport your camping gear for you to the overnight campsite and provide hot food under cover for you to wolf down while discussing the day’s adventures with other competitors and old rivals.
