I think I agree, so I'm aiming to get up early tomorrow and run in the lower temp, higher humidity. It's not a long run anyway. I don't know how people properly for fall marathons. Unless they live in Montana, Wisconsin or Maine.
I ran the Shamrock Marathon in VA Beach one year and got the runner's sh**s right at the halfway point. Held it til I got to mile 14 at the rest station, but there were so many people waiting. Found a construction site about half a mile down with an unlocked johnny. Fortunately for me, they must've cleaned it right before they left for the week.
