Brilliant account Richard...!
I was still having cramps in my fingers/hands yesterday.
The descent down Snowdon afterwards was also very tough. I'd drank a litre of water at PyP, and had another litre with me for the climb, but knew i needed to ration for the walk off.
The marshals had a limited supply of water at the finish, but really only for people who were completely out, so i was honest and told them i'd make my way down with the 300ml or so that i had left.... that was gone before Clogwyn, and it was a soul-destroying walk down from there (i usually jog down but could not manage more than a walk on saturday).
Straight in the shop in Llanberis, necked a litre of water and a can of cherry coke which made me feel incredibly queasy.
I'm just thankful i took a long-sleeved layer in my kit, so i could at least escape a bit of sun exposure on the walk down.
