Let's offroad / mountain bike / mtb / ride dirt

if you will be going to swinley regularly then it is worth copying this route

90% bike paths or you could go on the main road (it's fine to cycle along) then switch over to the foot/cycle bridge as the roundabout is a mare with nutters doing 60-70. plus there is a parade of shops next to the cycle route for 'refreshments' on the way home

I've added our route from Bagshot to the map http://www.gmap-pedometer.com/?r=2501219 . The end point is a reservoir that's in the middle of the expert mountain bike area. If you head down soon then these maps will be useful. One's a general map and there's two GPS logs which show some of the nice bits of singletrack.
