Garmin’s smallest and lightest module fits within the width of the strap.
Soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.
Forerunning, provides feedback on running form (cadence, vertical oscillation and ground contact time).
Capable of storing up to 20 hours of heart rate data.
From the manufacturer
HRM-Tri – Specifically designed for triathletes
Small and lightweight Heart Rate Monitor (HRM)
Garmin HRM-Tri is a small and light heart rate monitor from Garmin. Designed with soft rounded edges and no exposed seams, the strap remains comfortable during extended hours of training. It is designed to be worn when running, cycling and open water swimming. A simple bi-fold adjustment reduces elastic weight and makes sizing easy.
10 Months battery life
The battery lasts up to 10 months (assuming one hour per day use) with user-replaceable CR2032 battery. Enhance your triathlon experience by pairing HRM-Tri with Garmin Forerunner 920XT multisport watch.

HRM-Tri provides heart rate data in all three disciplines
Stores and forwards Heart Rate Data
For triathletes who want all the data, the Garmin HRM-Tri provides heart rate information from beginning to end. The HRM-Tri stores up to 20 hours of heart rate data during swims and forwards to the Garmin Forerunner 920XT GPS multisport watch or other compatible Garmin sports watch (Garmin fenix 3 or Garmin epix) after the session. It also sends real-time heart rate to the watch when the monitor is out of the water.
In addition to standard heart rate metrics for every leg of the race, Garmin HRM-Tri provides feedback on running form and running dynamics. The HRM-Tri has an accelormeter in the module that measures torso movement when running. When paired with a compatible Garmin product such as Garmin Forerunner 920XT, Forerunner 610, fēnix 3, epix or Tactix Bravo, it measures; 1. Cadence – the number of steps per minute, 2. Vertical oscillation – the bounce in your running motion (the vertical motion of your torso measured in centimetres) and 3. Ground contact time – the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
