Portumna Forest Half & Ultramarathon 2026 (6th June)

Despite taking place in a forest, there was no escaping the weather on Saturday 6th June in Portumna Forest in Co. Galway where runners had a choice of 10k, Half Marathon, Marathon or 50k Ultramarathon. Whatever the distance, it was a very difficult course with lots of tight U-turns at cones but that didn’t prevent Mark Darby winning the Half Marathon in 1:20:49, pulling clear in the closing stages to win by just over 30 seconds, leaving nearly 200 others in his wake. Among the 85 that chose the 50k Ultramarathon was Susan Glennon who dug deep to finish an excellent 4th overall in 3:41:30, the 1st woman to finish. Very well done to Mark and Susan [GD].
