Lirish - I've done this last two years. Train is fine and they will send minibuses to pick everyone up as long as your train is scheduled to get there on time.
This is a nice run, generally easier to follow than C2C (keep river on left or right of you) but deviates from the river at a couple of points where you have to be a bit careful. There seems to have been a problem with the maps sent out so you may want to check out these bits online. It can be squishy underfoot but has less hard surface underfoot so is easier on the feet etc.
hunterway - go for it, bring headtorch and snacks, take it easy , enjoy it and say hello to people.
Hi Katie - I always feel a bit crap after C2C, don't like hard surfaces.
