The Nos Galan race celebrates the life and achievements of Welsh runner Guto Nyth Brân.
Founded in 1958 by local runner Bernard Baldwin, it is run over the 5 kilometres (3.1 mi) route of Bran's first competitive race.
At its height covered by the BBC nationally as part of its New Year's Eve celebrations,[1] the races were halted in 1973 due to concerns expressed by the Glamorgan Police regarding the undue delay to traffic.
The race also broke with tradition, with three mystery runners, representing the present, past and future of athletics, carried the Nos Galan Torch.
After lighting a torch, it is carried to the nearby town of Mountain Ash, where the main race takes place.
