hey, is that joolz from cyclesport? if so hi there, hope you had a good holiday, next time you see brett get on his back about Mayhem, if not, hi anyway!
I've done the train out to edale before, it's really easy from lincoln. The trains out of sheffield have great bike space but the lincoln-sheff ones generally have a very pokey bike space. Nice cheap day out from lincoln, give yourself enough time and you can ride straight out from sheffield and save some train fare.
So is it possible to ride lincoln-sherwood pines on the sustrans routes? edit- just clicked your link, that looks ace, I'd been thinking there must be a way to get over there off road, looks like I've got myself an all-day-er in the making!
