Welcome to the Mourne Mountain Marathon website

The next Mourne Mountain Marathon will be 21st – 22nd September 2019

 The Mourne Mountain Marathon is Ireland’s only two day endurance and navigation event held each year in the beautiful mountains of Mourne in Northern Ireland.  It is run entirely on a voluntary and non-profit basis by a team with many years experience of organising and competing in this type of event.

2019 Entries Open 12th May

Spring is upon us and the MMM team have sprung into life  – scouring the Mournes for interesting places to camp and boggy places to run courses through. We have a bit of work to do to update the website and get SI Entries set up so we expect to open up shop in mid May.
