Kilworth Backyard Ultra
Kilworth, Ireland • 13 Sep 2025
The Kilworth Backyard Ultra is an extreme ultra-running event held in Kilworth Woods, County Cork. Participants run a 6.7 km loop with approximately 125 meters of elevation gain every hour, starting from the main car park. The course is fully marked, mostly on wide paths with some forest trail sections, and continues until only one runner completes a loop more than any other.
There are no aid stations on the course, but water and light refreshments are available at the start/finish area. Runners must carry mandatory advanced-level safety gear and may have crew support only at the base camp. The race fosters community spirit and offers a unique, challenging ultra-running experience.
