Finally did the full Marple-Rowarth loop with V,G and RG. If your fit you can do it in 2.30 hours. We did it in 3.30 hours and I was crawling at the end. RG has just bought a mountain bike as well, and he was struggling just as much a me, which made me feel a bit better about not being as fit as the others. All in all good fun, and the healthiest day I've had in a long time.
