My first 50 mile is tomorrow!
Weather right now depends on where you look. A high in the low 80s with very reasonable humidity. I asked the weather gods earlier in the summer to bless us with lots of nasty weather if they had the make race day nasty and they have agreed! While we didn't get as much gross weather as we could have, I had a couple of nice long runs in really gross heat/humidity. I've noticed that I feel much more comfortable in heat/humidity, so that is great.
So, I'll be out there tomorrow. I could run a 9:30 or I could be racing the cutoffs if it's really gross out. I figure a 10-11 hour finish is most likely.
Good luck to everyone out there!
