In reply to katerinaemalina:
If you want big long high lines (which is great if fitness isn’t quite up to normal) then look at the long N to S, (or S to N) lines....
Say Ambleside start, up one side of the Fairfield Horsehoe, then on up over Helvellyn, etc. You could book accommodation at either King's Head, or Lodge in the Vale. More ambitious, carry on up to Threlkeld. Head around Blencathra (Doddick Fell is nice) then Skiddaw House, Skiddaw, and back to Keswick for another stop over or just a celebratory drink and a £2 bus ride back to the car. Or....
Start Troutbeck, up Garburn Road, then long run over the High Street Range. Could overnight at Glenridding, or carry on to Pooley Bridge (Loadpot, Arthur's P etc). Transport back a bit more complicated as the direct bus over Kirkstone only runs in the summer.
Main thing is climb early, stay high, run far!! Hope you sort something nice! 😁
