Provo River Trail in the morning, 8 miles in 55:54. Did a 1.5 mile health test tempo in the middle in 8:57. HR was 155 at 6:00 pace. On the last quarter, sped up to 1:28, HR climbed to 157. Still 10 bpm higher than normal.
The latest HR drifts encouraged me to try an experiment. I brought a bottle of water with me and drank every two miles. This reduced the drift a bit - 142 at 7:00 pace uphill at the end instead of 145, and made the whole experience better. I also for the first time in a week did not have AK-47 cough salvos at all, not even after running the tempo or stopping at the end.
Ran with the kids in the afternoon.
