I completed a fun 20-minute Fartlek exercise this morning. The run was intense because my digital running coach called out the different paces by surprise and did not share how long the pace should be run. I was exhausted after 20 minutes. I was surprised to see in my data that I increased my max heart rate today with 8 bpm to 196 bpm. My average bpm during this run was 160 bpm.
