The Route


Nos Galan Road Races attracts runners from all over the world. The 2017 race attracted over 1,700 runners, and 10,000 spectators.

The main race starts with a church service at Llanwynno, and then a wreath is laid on the grave of Guto Nyth Brân in Llanwynno graveyard. After lighting a torch, it is carried by the Mystery Runner to the nearby town of Mountain Ash, where the main race takes place. The format of the race has changed several times over its history. The current race consists of four circuits of the town centre, starting in Henry Street Relief Road and ending in Oxford Street, by the commemorative statue of Guto.

Please be aware that there will also be an amended route for this year’s Nos Galan Road Races due to the construction of the multi-million-pound Cross Valley Link. The map below highlights this and the change of location for the turning point. The route have been accurately measured and certified.
