The South West Coastal Path is 630 miles and includes Dorset, South Devon, Cornwall, North Devon and Somerset.

This route is 99 miles of the North Devon section of the SWCP (arguably the most beautiful). People have run the SWCP with Damian Hall’s record averaging 100km a day. Unlike the SWCP, there are no requirements to travel on any ferry so this therefore is purely down to the runner. In addition, this can be run in one attempt without the need to sleep. There is significant elevation gain. One end is Marshland Mouth and the other is Glenthorne beach.

This route hits all of the mountains included in the Legend of the five sisters story http://sundayruns.org/community/the-legend-of-the-five-sisters/.   You start with the climb up Bear Mountain, then head to West Mountain, the Timp, Dunderberg Mountain, and Bald Mountain before heading back to Bear mountain parking lot by the ice skating rink coming out the Suffern-Bear Mountain Trail.  

John Newman submitted the route:

This 130km (80 mile) loop of the Blue Mountains weaves together jaw-dropping sights and a lot of the best single track in the area. It's a knockout. The loop can be run in either direction, starting from any point. Some sections are brutal but the views are worth it.
