have a crack at snowdon marathon then you know about pain lol.
Wor Lass has ran that one twice; she says the atmosphere and camaraderie are great. She also likes the Endurance Life coastal marathons and she's done the Gower one twice (that's in ruddy December and it's freezing waiting around for her to finish) and also the South Coast Devon one.
The Gower one is a bummer (apparently) 'cos of all the climb, mud, scree and beaches. I find this race difficult because of the lack of burger vans and general absence of catering facilities.

They can't be that tough though; she's only little. And look at 'legs' in the back of the picture, just mincing along!!
