I've not been to many races, maybe 4 now, but about the age of fell runners, it does seem to my eyes, that the average age of runners at races is about 40.

This is slightly worrying for the future of the sport, there are young runners, but compared to track/road/XC, there doesn't seem to be a similar correlation. I don't know why this is? Fell running outclasses track/road/XC hands down in all aspects. Maybe its because the track/road/XC get more media coverage.

That aside its definitely the best sport I've taken up for a million reasons, and have been helped massively by various runners, who are keen to pass on their tips and knowledge.
