The way points of this bicycle route:
Nominal start point - pick somewhere in Cambridge and join up
Short climb to get your legs working
Here, MTB riders can take the turn to the right and go the offroad route over the hill (go straight ahead when you get back on tarmac) joining back up with the route in Barrington
Short but steep climb
Really nice downhill, sliding under the motorway
Historic National Trust house. Good cake stop.
