In 12 hours I'll be driving to the start of the Blue Sky Marathon. This evening I'm setting my gear out, getting thoroughly hydrated and fed, and suffering from some kind of gastro-intestinal thing. Yesterday afternoon I was dizzy and tired. Now I've got some mild diarrhoea. I'm preparing as though I'll be fine in the morning since there's nothing else I can do about it.
A cold front is coming through tonight and there may be snow above 8500 feet. The high point of the course is 2000 feet below that and shouldn't be affected. Tomorrow is forecast to be sunny, cooler, and breezy. Better conditions than during my last long run on the course two weeks ago.
Being asleep by 8 p.m. will be hard, but I'm going to try. I'll have photos on Instagram and this site tomorrow.
