The Tollymore Trail Marathon on 8 November 2025 includes a 40 mile ultra, marathon, half marathon and 10km distance in the Tollymore Forest Park.
This is a challenging event with many steep climbs and descents. The course for the Ultra (3 laps), Marathon (2 laps) and Half (1 lap) is approximately 21km in length and is mostly forest gravel road and small sections of single track.
The 10km route offers a scenic run along the Shimna River, featuring key landmarks and a shorter, less intense course than the long course.
