I'm really really interested in signing up for the RunnersWorld Trail Blazer event (rwtrailblazer.com/) as trail running really appeals to me, all that greenery, nature & beauty and lack of hard surfaces / cars etc...
But how much harder is trail running over normal road running. I've been running the pavements for the last 9-10 months with only a smattering of trail running through local parks and what woodland paths I can find but locally, there's nothing more than half a km here, or maybe a km there so I can't get a real gauge for it.
If I can just about run 10k on pavements, realistically whats my chances of running 10k on a trail?
