Ran with Ted and ROTC Army cadet Shahay at 5:30 AM. Met them on the trail. Did not miss them this time. Had the hybernation issue again for the first 4 miles. When I met them, their pace (7:20) felt fast, although my HR stayed around 114. That is probably why it felt fast - in order for me to feel good at 7:20 I need the HR to be at least 122-124. Once I was out of hybernation, HR was 125 at 7:00-7:10 pace, and it felt very comfortable.
Ended up with 10.08 in 1:13:19 with the average HR of 118. Ran with the kids in the evening.
