Me,Me I will be helpfull! 😆
Starting from Keswick you need a nice well surfaced warmup, I would head out towards Bassenthwaite village on the A591 turning right at the Castle Inn,Stay on this road heading towards Uldale using the exellent climb onto Green how. Stay on this road to Caldbeck,Cafe/shop, turning right for Hesket Newmarket,Wood Hall,Low Row,High Row,Mosedale,Mungrisdale,A66.
You could return via the a66,to Keswick or head onto the A5091 via Dockray,Park brow,Glenridding,Kirkstone,decend via the struggle to Ambleside,North to Grasmere Dunmail Raise, Keswick.
The very best of luck from me on the fred whitton,possibly one of the toughest races in the world!
