The long way up to the Tan Hill Inn, Official Climbs #51.
Warm your legs up first though, bearing left at Feetham to climb the steep Turf Moor (Official Climbs #142) onto open moorland. Look out for the red grouse flying across in front of you at 12.25Km, just after you complete the Turf Moor segment. This is the famous Red Grouse which appears on Scotch Whisky bottles. Although a protected species, hunting is permitted (eg the "Glorious Twelfth") providing local population levels are not threatened.
After reaching the Tan Hill Inn at 26Km, swoop back down to your starting point at Muker in Swaledale; this is the reverse of the Fulgaz ride "Tan Hill from Muker".
"Any higher Mr Bond, and my ears will pop".
