Can talk you through route on Tuesday at club if you want? Particularly the "tricky" sections at the end of RV up and round to the edge and the bit through Menston.
Re: the last bit up the Chevin - don't worry about it - I pretty much consider when you've got to East Chevin road, it's all over bar the shouting in terms of effort - East Chevin road is downhill and you only need to let you legs go, as you can walk up the Chevin and then let the legs go back down into Guiseley.
