The Saunders Lakeland Mountain Marathon (SLMM) is a two-day mountain navigation competition (or race) that is held annually in the Lake District for pairs and experienced solo entrants.
The event comprises 7 courses for pairs of runners of which 2 are also open for experienced solo competitors. The first day finishes at a mid-way campsite. Competitors must carry the lightweight camping and safety equipment listed in the rules. Competitors need to be competent in the use of map and compass in the mountains. Many checkpoints require accurate navigation, which is even more important in misty conditions.
The Saunders Lakeland Mountain Marathon is organised by Lakeland Events Community Interest Company. Any surplus generated by the event will be distributed to registered charities that provide outdoor activities in the Lake District for disadvantaged young people and to charities which pursue improvements to the local environment
