It was said that his talent first came to prominence as he was helping his father herd sheep when he managed to chase and catch a wild hare.
One such legend has him running from his home to the local town of Pontypridd and back, a total distance of some 7 miles (11 km), before his mother's kettle had boiled.
[3] The first race organised by Siân o'r Siop saw Guto taking on an unbeaten English captain over a distance of 4 miles on Hirwaun Common.
But the race took a fatal toll on Guto: it is reputed that during the post-race celebrations he collapsed and died in his lover's arms after an over vigorous congratulatory back-slap.
The race was created by Mountain Ash resident Bernard Baldwin, a PE teacher in Pontypridd and a President[dubious – discuss] of the Amateur Athletic Association, in 1958 as a memorial.
The statue in bronze of Guto Nyth Brân in the centre of Mountain Ash was commissioned by Mid Glamorgan County Council in 1990 and sculpted by Peter Nicholas.
