We did this back a while ago and to make it a bit more fun we returned via Landsdowne Lane .Yep thats the one one of the top hills in England.Only peaks at about 20 % i think so a liitle stop halfway for a breather is allowed. Food at the Wellow Treking centre which is normally a nice little food stop. Dont forget your little lights as it is VERY dark in the tunnels.https://ridewithgps.com/routes/22037411
