OMM designs & manufactures technical clothing & equipment made for the conditions & terrain faced by mountain runners & endurance athletes.


Gather your tribe for an epic weekend in the heart of the Lake District.

This is the weekend for those who love the outdoors.

Take on trail races with GRASMERE GALLOP or the OMM LITE adventure race which will take you around the fells surrounding Grasmere.
Learn to navigate or sharpen your Nordic walking skills with workshops all weekend.

With catering, bar & camping on site and inspiring guest speakers taking to the stage, there’s something for everyone to get involved with. 

Non-competitors are welcome too so bring the kids (and someone to look after them) while you enjoy the trails.

Here you will find the whole OMM range of lightweight clothing & equipment, specifically designed for the high demands of the mountain runner, with specifications drawn directly from experience on the Original Mountain Marathon.


The RE:OMM project is our latest step towards reducing OMM’s environmental impact.

Our aim is to ensure no OMM products ever enter landfill.
Through RE:OMM, you can expand the lifetime of your kit with a professional repair.

Shop great deals on refurbished products, and recycle your old OMM gear responsibly.

The OMM is designed to test your abilities in the mountains. Anyone can get up Scafell Pike on a sunny day, but can you make good decisions when the clag comes in, visibility has gone, you’re tired, you’re wet, cold & there’s no paths to follow?

Held at the end of October to guarantee bad weather. To compete you’ll need a team mate, mountain experience & dogged resilience. 
It’s all about decision making, what kit you’ll need, what route to take, how hard to push & what to do when you get lost… which you will.

It’s not easy, at times soul destroying, but the experience is unmissable!
