Ras y Moelwyn 2013
Not only does the sun shine on the righteous but also on the runners of Ras y Moelwyn. It’s got to be the most atmospheric of all the Welsh mountain races and is always held the day before the London Marathon. Just over a hundred set off on the 10.5 mile route rising 2,800 feet before plunging back down to Blaenau Ffestiniog. The winner was home in 79 minutes. Thanks to Antur Stiniog, all the marshalls, first aiders and members of South Snowdonia Mountain Rescue for making it a great event.
