Friday Night Heat

7 miles in the early evening heat. This was my first time to run Yasso 800's, which I picked up from an issue of Runner's World. In this workout you run 2 miles of warmup, then repeat 800m fast + 400m cooldown six times, and then finish with 2 miles of cooldown. I tried to run the 800's six times, but on the fourth one I had to walk because of the heat and the hills. Plus I ended up cutting the final cooldown by over a mile, so not the most auspicious start to the new workout. I don't know if it was the stress of the week at work, not getting good sleep, eating dinner about an hour and a half before the run, or just the heat, but it was a tough workout all around. I'm going to do my long run on Sunday morning, and I'm thinking about getting up very early to avoid the heat and humidity as much as I can.
