The Saunders Lakeland Mountain Marathon (SLMM) is an annual two-day mountain marathon held in the English Lake District ('or its environs', such as the adjoining Howgill Fells) in early July. It was founded by David Meek, and sponsored by a long-time UK manufacturer of light-weight tents.
The SLMM has been held annually since 1978, apart from 2001, when the Lakeland fells were closed because of the Foot and Mouth crisis and 2020 because of the Covid-19 outbreak. 2025 was therefore the 46th event.
It is usually considered to be less 'hair-shirt' than the slightly older OMM (formerly the Karrimor), since the weather is often milder, the courses slightly shorter, and the overnight camp is often found to be within walking distance of a pub. However, there have been notable exceptions to this - in 2004 (the 26th event, out of Coniston) consistently poor weather over two days forced many teams to retire. In 1997 (the 20th event, starting from Grasmere) courses were set which meant many teams were still out on the Sunday evening, long after the prize-giving was due to take place.
The current event comprises seven courses for pairs of participants. The organisers encourage young competitors, with lower entry fees for Under 30s and there is a specific, handicapped class for parent and child (age 14+).
The Backpackers Club has traditionally provided marshals for the event. They assist at the registration and mid-way campsites and man the many checkpoints spread around the various routes.
The event uses largely volunteer basis. In 2018 the ownership was transferred to the newly formed Lakeland Events [1] Community Interest Company (CIC) and is run on a not-for-profit basis.
Because of the popularity of the Lakes, courses are usually set to run 'across the grain' of the country, away from popular paths, so as to minimise erosion due to the race.
The current event comprises seven courses. All are for pairs of participants. [2]
Six of these are "linear" courses where participants must visit all controls in the prescribed order and the fastest cumulative time over two days wins. They are named after Lakeland fells: Scafell, Kirkfell, Carrock Fell, Harter Fell, Wansfell, Bedafell. The relative short Bedafell course is advertised as specifically for parent or guardian and child, and suitable for new entrants.
The other is the Fairfield "score" course - first introduced in 2018 - where participants visit as many controls as they can in a prescribed time limit, with penalties for being late back. Different controls have different point values and the highest cumulative overall points over two days wins.
There used to also be a "Klets" course, open to either pairs or solo runners, where participants had to collect all the controls, in any order, over the two days. The course was last run in 2018 after which it was removed on safety grounds for solo runners.
