10miles, maybe 20 miles. Feeling lucky punk?!
Easy 30 miles, but wouldn't recommend aiming to push much further!
I started to run out on the M6 up a slight hill, got to the top and cut out completely, sign at top of hill said Corley services 1 mile, clicked into neutral, slipped into hard shoulder and cruised the whole way into the services and all the round to the station, got off the bike and a little jig!
