This is a new route, which loops back to my house at 356 km to avoid needing to use motels. It will not be easy. The first half has a lot of climbing. There is a total of 16 km of gravel- 12 km on Campbell Creek Rd., and 4 km on Tappen Notch Hill Rd. There are no stores on the route from Nicola Lake to Pritchard-  about 100 km or so. Where you rejoin Hwy 1 at Pritchard there is a store just off the route across the highway, and another just before Chase. Expect limited hours of operation.
