On 8 November 2025, runners will return to the breathtaking trails of Tollymore Forest Park for one of Northern Ireland’s most challenging and scenic off-road events — the Tollymore Extreme. The race offers 10K, Half Marathon, Marathon, and Ultra Marathon options, each following a looped course through dense woodland, riverside paths, and the foothills of the Mourne Mountains. Expect tough climbs, muddy tracks, and technical single-track trails that test endurance as much as determination. With sweeping forest views and crisp autumn air, the Tollymore Extreme combines the raw beauty of nature with the satisfaction of conquering true trail distance.
