About
The Llanelli Half Marathon & 10K is one of the longest-running road races in the region, taking place along the beautiful Millennium coastal path and closed roads. The course features flat terrain with maximum elevations of only 15m for the 10K and 16m for the half marathon, making it perfect for first-time runners and those chasing personal bests. Starting and finishing at Festival Fields, participants enjoy stunning coastal views while running through scenic Carmarthenshire.
