Climb up from on the forest roads as stated, do the blue first, then do the south loop then do the north loop and if you feel inclined carry oninto the south again.
alternalty have an early start blast the blue and the red in the order above, then blast back down to thornthwaite along cycle way to keswick and do the ride along the bridleway disused railway to threlkeld then up past the blencathra centre and around the corner of lonscale fell and down spoony green lane. I think you can buy a route map in KMB or just do a search for corner of skiddaw. this ride takes a coupleof hours.
could easily do whinlatter morning and this in the afternoon. Maybe drive up and down to whinlatter to save alittle time but not that much. Will sho mates a diff style of riding as well.
