70 degrees with DP 66 made this my warmest run since the Chicago Marathon. Wore long sleeve shirt and cap as part of my heat acclimation process. Pacing run to test my ability to maintain 7:30s the entire way (for a potential pacing gig on Saturday). I was sweating like a whore in church, but my legs felt strong the entire time. Splits were 7:25, 7:22, 7:28, 7:33, 7:31, 7:27, 7:29, 7:24, 7:31, 7:28.
