January 10th 2016. Note: still closed as at 24th February 2016.
The C2C coast to coast cycle route is closed at Thornthwaite Forest for tree felling. This would normally be part of the Workington to Keswick section.
There is a diversion signposted as you come out of Cockermouth along the Strawberry How road. Turn right as signposted and cycle as far as the crossroads, then turn left for Lorton.
At the edge of Lorton village you can go left and up the main Whinlatter road, or preferably go on into Lorton and join the Whitehaven to Keswick route.
