Filmed on the hottest day in UK history, this loop starts and finishes in Leyburn in the heart of the Yorkshire Dales with a steady climb onto the top of Grinton Moor. Keep your head down as you pass the Army live firing ranges, before climbing Greets Moss (Official Climbs #144) to return to Wensleydale and a loop around Bolton Castle which held Mary, Queen of Scots for six months in 1568.
Finish the loop with a nice 3.5km TT stretch coming out of Redmire into Wensley.
