Woohoo! Route looks quite different for 2020... same shape, different roads.
Friday night is much the same but turning before Minehead means different route over Exmoor (no Dunkery Beacon)... then rest of Saturday looks similar (with deviation to Tiverton on the way up) until the route changes on the way back down after Sedgemoor, heading towards Bridport rather than Axminster with a different control for the first night stop.
First half of Sunday is very different, with a new route through Somerset and the Mendips, but similar to the original after the turn at Michaelwood and down to West Stafford. The final day looks completely new!
