i think that im gonna have a go at this.
will make it a long weekend, Start out from NDevon on the Friday, look for a cycle friendly pub / campsite / ditch for the night & finish of on the Saturday. Maybe have a go for the return in one day on the sunday.
I've only ever really done this route at 100mph in a rep-mobile, so any pointers for a fixed friendly, quiet bike route would be much appreciated.
