We did LEJOG in 9 days unsupported staying in B&Bs, earlier this year. It was a scenic route, ended up being 960 miles. We pre-booked all the B&Bs and planned a gps route for each day (mostly based on the CTC B&B route with some detours to friends houses we were staying at). You don’t need much stuff tbh, I fit everything in a Carradice Barley bag (with spare footwear tied on top). Shortest day was 85, longest 140.
It was great fun (thou we had amazing weather, even in the highlands)!
