HRM / heart rate monitor
A heart rate monitor (HRM) senses how quickly your heart is beating and sends this data to a display or data recording device. Heart rate is usually shown as a number (either beats per minute or zone).
Many GPS training devices can gather data from a heart rate monitor, allowing you to correlate heart rate with pace/speed, elevation change, and location data.
GPS training tools that can work with a heart rate monitor include:
- Garmin Forerunner 301 & 305
- Garmin Edge 305
- Timex Bodylink
