OMM About Us

Here at OMM we are committed to two things: running the first and most famous and largest mountain marathon in the world, the OMM and developing the very best Leanweight packs, sleeping systems and garments to help adventure racers and OMM entrants in their quest.

OMM - The Product

OMM's heritage was the Karrimor company  which was responsible for creating some of the outdoor's great iconic products: the orange Whillans and purple Haston Alpiniste, the yellow Karrimat, the Jaguar SA pack, KSB's, the first and original lightweight boots, and not to forget the KIMM AR35 (now the OMM classic marathon 32). Most British expeditions of the 1970's and 80's, many led by Chris Bonington, were supplied by Karrimor.

Today OMM, together with a team of enthusiastic supporters and lead users, are re-inventing the meaning of “lightweight” with many innovations to create products with the perfect blend of performance and agility for outdoor athletes, of any age.

OMM - The Event

Since 1982 the event team is under the continued leadership of Jen Longbottom. The event has been held each year since 1968. It is the original mountain marathon and forerunner of all adventure racing. 2006 saw new sponsorship, new name and the same great organisational team. From 2006 the event was therefore changed from KIMM to OMM, the Original Mountain Marathon.
