Funny you all should be talking about humidity - I sure missed the west coast humidity today.

I did 3 miles per my plan on Friday here in FL and it was OK. It was at about 6 pm, so kinda hot but I had plenty of shade on my route. I didn't really get over-heated until about 2.5 miles, so it was survivable. Oddly enough, the humidity allowed me to run it comfortably without water where I always have a really dry mouth at home after 3 miles.

Today I did my long run - 10 miles. It felt like 20! Holy hell...it sucks running here. I was out there by 7:30 but it really didn't matter. 92F and 88% humidity. Half my route was in the sun without shade and I was seriously wilted. I parked in the middle, ran 2.5 miles in one direction and then turned around and then 2.5 miles in the other direction and back again. That allowed me to keep cold water at the car to cool off and resupply at the half-way point. I should have run it the other way around though because direction one was shadier than direction two (lesson learned for next time!). At 8 miles, I really wasn't sure I was going to finish and I started walking in the tiny shade spots to try and cool down a bit. Oddly enough, my overall pace pretty much matched the pace I do at home for long runs, even with all that walking. I was thinking it was running on flats vs hills, but really, I think it's running on an uninterrupted MUP vs running on sidewalks with lots of traffic lights.

I will say that I've never been so glad to be done with a run as I was today!
