Have you gone through this process to find out what your max heart rate is?
Finding Your Max Heart Rate
To find your max heart rate, strap on your
Echelon heart rate monitor, jump on the bike, and start with a ten-minute warm-up. Next, every 30 seconds, increase your output by 15 watts (or 1 mph of speed). Your max heart rate is the last 30 seconds of work before your watts decrease. Take note of this number, and use it to create your heart rate training zones.
Googling “heart rate zone calculator” provides a plethora of websites to assist with your calculations. Several mobile apps (
iOS,
Android) offer similar guidance. Below is output from FitDigits.com’s
heart rate zone calculator.
