I tend to measure ride intensity by my heart rate. Like many, I monitor my heart’s bpm using a chest strap, recording it with an app (Wahoo’s app, in my case.)

Say, this morning, I rode 20 miles at an average heart rate of 150 bpm, for 1 hour 30 minutes. That’s 13,500 beats.

How far could I walk, jog, or run, given a comparable heart rate budget? Tomorrow I’ll find out, then do the math.

While my heart and lungs remain a constant for either type of exercise (as a hypothetical), I’m guessing it’s how my legs respond -their relative condition for transporting my entire mass on foot- that may well differ from cycling results.

Maybe I’ll report back here when I’ve got some useful results.

Cheers!
