I got a 3-miler in yesterday after work. It was about 70 degrees outside and mostly overcast except for a few peaks of sun and a little breeze so it seemed nice. The last 1/2 mile was AWFUL - my energy was completely gone, like someone had just flipped a switch and stopped it. After I got home, I checked the weather and the humidity was 73% so 100 degree dew point. My hat's off to all of you who live near the coast - how do you DO it? Wow! Looking forward to a bike commute to work tomorrow - if the weather cooperates.
