I think my next long run will be tuesday; no doubt all the snow will be gone by then, haven't seen a forecast for the Buckden area for tuesday yet but I'm hoping for cold and sunny, a light breeze and no rain!
Aah, the Fellsman! I'd second windproof gloves and overmitts combo. Hopefully the weather at the back of April will be kind, but it isn't always and it's good to be prepared.
Also, remember that if for any reason you have to give up, you could be sat around in the middle of the night for quite a while, so a properly warm, lightweight jacket is a good idea, even if (hopefully!) you won't need it.
