I am planning to ride JOGLE in summer 2017, putting the route together at the moment. I am looking to ride to Fort William and then via Loch Lomand down to Dumbarton, my plan was then to pick up the Clyde Cycleway and ride 'through' Glasgow to Hamilton and pick up the B7078 down to Gretna. Information on the Clyde Cycleway is not too clear on the road surface, pictures show a paved pathway in parts however other information says that parts can be very muddy after rain. Is the cycleway suitable for a road bike with 700 x 28/32 tyres or do I need to find an alternative route? If suitable for a road bike, is it a slow route or would I be able to keep to a 12 mph average speed? Thanks for any information.
