Heart Rate hovered around 145-160
kept it around 145

How I felt during the run. Slightly dehydrated only one waterfountain did not bring waterbottle (dummy) HRM was uncomfortable as I wasn't used to having it around my chest.

Stopped twice for water.

How I felt afterward satisfied (no injuries) but concerned.

Concerns: the fact that my heart rate went past 140 so easily. Can't rely on feeling grr...
