( i know these lot my race sparingly on the fells but when they do/did compete there never far from the front) John Brown showed in true fell races in the english champs, billy and martin both performed well on true fell races as younger athletes both focusing on mountain running, jeff norman was extremly good on even the toughest fell courses, and i my be wrong but didnt Andy finish second at kentmere once? martin jones and dave lewis once again may not have raced on the fells often but when they did they performed very well, dave was only just second in the rossendale hills race i think as a 19 year old to a certain John Wild(correct me if im wrong!). More recently Nick swinburn with his win at moel elieo beating the top guys last year. Also looking at the FRA relay results the Brownlees performed well. This is more....

Its worth noting i didnt just mean the roadies which try there hand at fell running, if we look at how some of the proper fell guys,
simon booth - not sure if he's gone sub 30 but has been close to 50 on the brampton carlise
Ricky lightfoot - again maybe not quite sub 30 but does very well on the xc often beating those capable of 30 min 10k
john heneghan - same as ricky but possibly faster?

I suppose what i mean is that a person with such speed can achieve well on all surfaces, i think speed is neglected by many fell runners as getting the strength is alwell and good but you'll only be able to do well on certain courses, where as those with the leg speed often perform far better alround.
