Tried a new running location at a nearby park where it seemed more even. Found a nice loop around a lake that was about .9 miles. Finished 1st mile at 9:55 (I got lost trying to find loop), took a stop then ran till 1.75, walked a few then finished last quarter mile. Averaged 10:07 pace overall. I think the heart rate monitor on my watch might've errored out. Average heart rate was 130 (can't be right). It didn't feel like 130. 2 weeks down, 24 to go for marathon in December.
