Looks like I may get to try out my rain gear. I was planning on leaving wednesday sept 13th but they're predicting 25-30mm rain (1") between wed and thurs , then chance of more in following days.
I'm planning a pretty long (for me) first day (95km / 60mi) and would rather not be soaked the whole way, but I'm also really anxious to get away. Hopefully there's still time for the weather to change.
Edit: I just freed up Tuesday which is supposed to be sunny to give me a better option. I don't mind rain as much once I'm somewhere.
