Garmin Heart rate monitor belt

Your heart rate data in all three disciplines

• Specially designed for triathlon
• Our most compact and lightweight heart rate monitor (HRM) ever designed.

• Stores and transfers heart rate data on Forerunner® 920XT

Add a new dimension to your triathlete experience with HRM-Tri, which you can pair with Forerunner® 920XT1. The HRM-Tri accessory stores heart rate data underwater and transfers it to the 920XT. Our most compact and lightweight module ever designed fits inside the strap. Its soft, rounded contours and flat seams make it an ultra comfortable strap, even out of the water.

Running Dynamics

The HRM-Tri monitor has a built-in accelerometer to measure your bust movements in order to calculate 3 stroke data: 2

The cadence: number of steps taken per minute. It shows the total number of steps taken (left and right feet combined).

Vertical oscillation: the rebound of your movements during a run. It indicates the vertical movement of your torso, in centimetres. HRM-Tri is compatible with several training products and displays your heart rate when paired.

Ground contact time: corresponds to the time spent with your foot on the ground at each step while running (measured in milliseconds).
