Jamba, if you want a GPX, gimme a shout.
Best done as a decent big day from Ambleside IMO. There’s a bridleway down past the turning for Holbeck Ghyll that takes you over to Troutbeck.
From there, up Garburn to the top, then keep going onto Yoke, Ill bell, Mardale Ill bell, froswick, then you can either go round the nice contouring singletrack to the east, or carry on up onto thornthwaite for awesome views.
Then down to Nan bield and into Kentmere. Here you have a choice, if you’re goosed, go over High Borrans to troutbeck then down Jenkins crag to Ambleside, if you’ve still got juice in the tank, add in Long houses up onto Staveley head fell and the three rivers descent too. Then High Borrans onto Jenkins crag.
Tis a fine days biking indeed.
