Llanelli Half Marathon & 10K 2027

The Llanelli Half Marathon & 10K offers runners a flat road race on the Carmarthenshire coast, with 13.1-mile and 6.2-mile options. It is one of the longest-running road races in West Wales, UKA licensed, and intended for a broad field: first-time half marathoners, club runners, and those chasing a personal best. The route utilizes the Millennium Coastal Path and closed roads, with minimal climbing: the listed maximum elevation is 15m for the 10K and 16m for the half marathon. The race is based at Festival Fields in Llanelli, with finishers returning there after routes that pass North Dock and follow the coast. Depending on the setup, the half marathon may start at the Tata Steel Trostre site while the 10K starts at Festival Fields, before the two fields merge near North Dock. Runners see views of Llanelli Beach, the Loughor Estuary, and the Gower Peninsula, and finishers receive a bespoke recycled zinc medal. Reviews indicate a well-organised, friendly event with supportive volunteers, even in wet and windy conditions.
