Today I felt like I was running through fog. It's only in the mid-70's but it's 81% humidity and I didn't think I'd make the 4 miles today. In fact, my pace was a full minute slower than a week ago running the same route.
I hate running in this kind of weather.
Wisely I'm using intervals for running now - 5 minutes running/3 minutes walking. When I can cover 8 miles, I'll adjust the timing but it seems to be a good set for my current level. It helped me get through the wall of humidity this morning.
