Here were the full stats and splits from the run.
It was beautiful out (low 50s and low humidity).
Despite some fatigue in the legs from last week, I was able to run a nice negative split. Something like 1:25:15 / 1:23:30 for first and second half.

Most interesting learning:
The impact of temperature and humidity on performance is dramatic.
Same course with same fitness one week apart. 70 and 90% humidity last week vs 50 and no humidity yesterday.
Mile 21:
- Hot: 6:42 pace at HR 182
- Cool: 6:14 pace at HR 170
Crazy.

Special thank you to @JohnGoldman for the bib and @HankFrank for the assist.
