Proposed new route with description on mapmyrun if interested
Basic outline is-Start at Croxby top, follow the undulating Croxby crawl route but at Swinhope go straight on rather than turning left and climb Swinhope hill. At junction with A18 (bottom of hill before Clickem Inn turn left towards Hatcliff. Go through Hatcliff and head out on the road towards Beelsby. At the t junction in Beelsby turn left back to Croxby top then do one lap of the infamous Croxby crawl route and finish on heartbreak hill.
p.s the run is up and down heartbreak hill just to finish you off !!
