5.85 Miles In Forest Park

Was volunteering at the Run For The Stars 5K in Forest Park, so got there early and ran a loop with Bob before. Was humid, but not too bad. Bob needed a pit stop during mile 5 and I didn't stop the garmin right away. The garmin did manage to stay on the whole time. I'm beginning to think it's moisture related as it seems that if it's raining, or if I'm sweating a ton, it seems to have more issues. 5.85 miles in 57:36 with an about 1m30sec stop during mile 5. 9:50 average pace, 149 average heart rate, splits of 9:46, 9:59, 9:03, 9:27, 10:57 and 9:46 pace for the final .85 miles. Run felt good despite being the 3rd day in a row. Temps were going up quickly, it was 61F with a 57F dewpoint at 7am, and 66F with a 58F dewpoint at 8am, so was sweating pretty good.
