No way she ran 6k in 30 minutes with an average heart rate of 99bpm! Without blowing my own trumpet, I’m pretty fit. I train & coach & run 5/6 times a week. My average BPM on my runs is around 130-140. Which is completely normal! Also her average speed is 9 kph according to that screen, which shows it’s a lie or at least highly inaccurate. To run 5k in 30 minutes, you need to be running around 6kph. So 6k, you’d need to be running even quicker! Unless it’s in miles per hour but that seems unlikely if the machine is tracking in kilometres!
