First day starting the Couch to 5k program. Though it would be easy, more challenging than I thought. I jogged a little less than I usually do, but the interval switching allowed me to keep my heart rate up longer. Did most of the run in my mask. I hope I'll make more progress sticking to a program instead of just freeballing it. Been jogging for a couple of months now and haven't seen much progress.

• I should slow down the pace of my jogs.
• Invest in a stopwatch instead of iPhone.
