108 degrees Fahrenheit, that´s what the thermometer in my car´s computer was displaying when I got in to drive to tonight´s track workout at Grissom High School. When I arrived, there were already 10 or so runners warming up. Wow, I didn't expect a lot of folks to brave the heat tonight. Shannon had come up with the following workout: 4x mile repeats at sub half marathon pace with 2 minute recovery jogs or walks and a 1 mile warm up and 1 mile cool down. Both Shannon Jacobs and Eric Charette were kind  enough to slow down to my fast pace for a couple of laps to pull me along. I ended up running 6:40 minute per mile pace average for all 4 repeats. Not bad for a sweltering speed workout on a completely exposed track.
