Noon run, mostly sunny, temp. 50'
Decided to run the first 4 miles wind aided at marathon pace. I ended up with about 6:50 miles for the first 4 miles and didn't know if that was really a little faster than marathon pace. Then when I turned around and headed into the wind I decided to stay at that same 6:50 pace which was definitely faster than marathon pace and the last mile I threw in a 6:15 mile to really get the heart rate going.
Time 56:38, Mile avg. - 6:45
