Race details
Mourne Mountain Marathon 55K was a running event with Full Marathon, 55 km, 35 km and 45 km distances in County Down on Saturday 19 September 2026. The Mourne Mountain Marathon is a two-day, team-based navigational endurance event in Northern Ireland from 19 to 20 September 2026. Teams of two enter one of four categories, covering between 35km and 55km across the two days. The courses range from beginner runners/navigators up to elite class and take on some of the most breathtaking and challenging terrain in the UK and Ireland. At the start of each day teams are presented with a route card with a number of control markers. They must visit each control in the prescribed order but may choose their own route between each marker. A feature of the event is the overnight camp at which all teams must be self-sufficient with everything being carried throughout the two days of competition.
