Here is the blank map for Saturday. 40 pre-entries so Jens has printed 50 maps. You can ride any type of bike but, as we are called NYMBO, prizes will only be awarded to leading riders on mountain bikes this month.

I hope the mountain bikes have to have proper nobbly tyres on. How much off road is there?
I think the optimum route to get all of them would involve no more than 8k off road and most of that’s on gravel tracks.
I’m not checking tread depth or tyre pressures! Just no prizes for road bikes, cyclo-cross bikes or tandems this month.
Up to 48 pre-entries now!
