LWaB, jsabine, Manotea, or anyone else who can't make the date...
I've test-ridden the route a few times myself and I'm fairly confident it is sound, but I would welcome a fresh pair of eyes on it, so if anyone fancies doing a routechecking 'helpers' ride between now and 2nd September, let me know. I'm happy enough with the GPX files but feedback on the routesheet would be especially welcome. I would potentially join in the routechecking ride if I'm free, or at very least buy the helper a pint at the finish.
Obviously this is not carte blanche for a load of riders to do a secondary event - rules dictate one or two routecheckers at most.
