A heart rate zone is simply a certain range of beats per 

minute. Heart rate zones are generally based on a percentage 

of your maximum heart rate and are numbered from 1 to 5 

based on intensity (1–lowest, 5–highest).

For each sport, the Forerunner 301 contains a set of default 

heart rate zones, which may not reflect your heart rate 

zones accurately. Consequently, the Forerunner employs 

an extremely valuable feature called AutoLearn, which can 

automatically determine your heart rate zones over a period 

of time and calculate your maximum heart rate.

AutoLearn is turned on by default in Running mode, so the 

Forerunner begins gathering data to calculate your heart rate 

zones from your very first workout—no setup or calibration 

required. 
When the Forerunner gathers enough data to calculate new 

heart rate zones, a message appears on the Welcome screen 

immediately after you turn it on. Thereafter, the Forerunner 

continues to gather data and adjust your heart rate zones 

to reflect your current fitness level. If the zone changes are 

large (3 bpm), a message appears when you turn on the 

Forerunner; otherwise, you will receive no notification. 

Other things to know about AutoLearn:

•  To calculate your heart rate zones using AutoLearn, 

you must spend some time training above your 

lactate threshold. See the Appendix for more 

information. 

•  Calculating your heart rate zones may take one 

workout or several, depending on the intensity of
