Kilworth Backyard Ultra

Kilworth Backyard Ultra

Kilworth Backyard Ultra is a loop-based ultra event in Kilworth Woods, County Cork. The course is a 6.7 km loop with about 125 m of elevation gain per lap. The route is fully marked and mostly on wide paths with a few short sections of narrower forest trails. Marshals will direct participants for the first laps. There are no aid stations along the course; water and light refreshments are provided near the start/finish corral.

The format follows the backyard ultra rules: runners complete the same loop repeatedly, are eliminated if they fail to complete a loop within the allotted hour or fail to start the next loop, and the race continues until one runner remains. Crews are allowed at the base camp only; no outside aid is permitted on the course. Trekking poles are not permitted.

Entry information lists an entry fee of €50 and a limit of 100 places. Entries open Sunday 19 July 2026 and close Friday 11 September 2026.
