That's the beauty of it though isn't it.. but also why its difficult. Those 'I survived' experiences are part of fell/ultra running/climbing/hill walking. My first race since leaving school was at 22 when I bet a mate a £5 I could run the WHW in 2 days, then found out about the race, and 6 weeks later was falling asleep on my feet after 80 miles....with a resultant DNF... but it got me in the sport...
I remember one guy, a hitch hiker, doing one of Yiannis's races, Arenig Fawr, after he was picked up by a runner, talked into racing and given the gear to run...
There is a really hard balance to maintain between accessibility and safety...
In North Wales we simply do not have enough runners, 13 runners in a recent race... so for me the promotion of the sport is a no brainer issue in certain areas.
