I'll have to try it out over Christmas. For the last 2 year's races I've taken just under 13 minutes from Uldale to Linghaw. It's at least a 3 minute descent to the bottom of the valley at full whack, so that would leave less than 10 mins for the ascent again. I climb Blease Fell in about 11 1/2 to 12 mins which is a comparable ascent. So I doubt it's a goer. More to the point; there's enough climbing up Blease without adding any more. I'm daft enough to give it a go though just for the record. I'll let you know the result.
