Brecon to Cardiff Classic

The Brecon to Cardiff Classic is a 70-kilometer ultra running race following the scenic Taff Trail from Brecon in the Brecon Beacons National Park to Cardiff. Now in its 12th year, this fully marked, one-way race features diverse landscapes, including dramatic mountains, waterfalls, reservoirs, and areas reflecting Wales’s industrial heritage. The route begins with footpaths and forestry trails, then transitions to an off-road cycle path after Merthyr Tydfil, passing landmarks like Pontsticill Reservoir, Cefn Coed Viaduct, and Cyfarthfa Castle before finishing at Nantgarw near Cardiff.

The event offers comprehensive support including transport, timing, refreshments, and facilities, making it a classic in the ultra running calendar. Visit the organization's website for the most recent information.
