After work yesterday I ran 5K on an indoor track at a gym. I ran 5 intervals of alternating 3 minutes and walking 2 minutes.
It was not without incident.
Halfway through the third interval I had to stop to use the bathroom. (That's the great part about running at a gym - the locker room was right there!)
When I got back on the track I was determined to do five intervals, which is one more than I did when I ran on Saturday.
It was amazing. I pushed myself, and it felt great. I even snuck a selfie during my last quarter mile.
