Nice route if you only have a few hours and want to see alot of bristol. Covers the Downs playing fields, Bristol Zoo, Clifton suspension bridge, Ashton Court, Avon Gorge, the Harbour, the City Centre, Stokes Croft and Finishes on the Gloucester Road (good coffee and beer).
Only a few hills to contend with, so fairly easy ride. Could stop half way for lunch at Aston Court with views over bristol, or another nice stop off for a drink, towards the end of the route, is at the harbour at either the Pump House, Cottage or the Arnolfini.
