Not too sure how it rates against other fell races, but I took part in the Charmouth to Golden Cap race on Saturday and loved it!! I found the downhill bits the most fun, where I applied the "wisdom" of going as fast as I could and achieved a sub 4 minute mile
Apart from the fantastic scenery and excellent organisation, there was a great atmosphere amongst the runners, which made it so enjoyable!

Living in Surrey, there aren't that many (any?) fell races close by, so I may well be visiting some friends in Sheffield on a more regular basis
