The Mourne Mountain Marathon is a classic 2 day navigation and endurance event for teams of two. At the start of each day teams are presented with a course as a list of control points which are identified by 6-figure OS map references. They must visit each control in the prescribed order but may choose their own routes between them. A feature of the event is the overnight camp in the mountains at which all teams must be self-sufficient with everything being carried throughout the two days of competition. The camp is basic but the views and the camaraderie are always great.
A 6hr Score race is also available on the Saturday for those who can't commit to the full 2 day event.
N.B. The courses are planned using the Mourne Mountains 1:25,000 map published by Harvey Maps. They are available from most good online retailers and "High Street" outdoor pursuits shops.
