The long route in the STW PDF has a few road sections that can be avoided. We prefer to stay off road as much as possible and ride the ridges.
Here’s the figure of 8 we do – start as the long route in the STW PDF, but climb up to the radio mast on 9 barrow down, then descend to Corfe. (Extra climb/descent)
Go out of Corfe to the SSW, over Corfe common, join the STW route.
Just after Kimmeridge, check the flags etc and go west on the bridleway, take first right hand bridleway for a fun descent down to the stream. Head north, then take the super steep (challenging climb) dog leg BW to the right. Climb up to the ridge, past the Grange Arch and follow ridge back to Corfe.
Lunch in model village cafe.
From Corfe, Nine barrow down all the way to the Swanage road, then turn left and then right climbing up to the obelisk, then ballard down and old harry, Studland and a pint in the pub. (As per the Medium STW route)
Would be interested to hear of any extensions to the West another 10 miles would be great.
