As Daz says, I am told that the weather forecast is pants for Friday, so it'd be a recce in the clag.
However, Mrs. Crumbly was going to perhaps have a look at the start of Leg 3 and part of the Old Counties Tops route, so may have a go at something if there is a gap in the weather.
If anything looks feasible, I'll post on here as early as poss.
