Hey, fellow sportsperson, It's Kevin here the owner of this super cool website. I would like to ask that if you find this unit listed cheaper at another store please give us the opportunity to try beat or at least match that price for you. Please drop us an e-mail via the contact us page with a link to the competing product for us to review.
Remember, we are a small & dedicated team that are trying our best during this challenging time and affording us the opportunity to try to compete against the really big corporate stores can only be done with your assistance. By supporting our small business you are helping us keep our team working and supporting their families.
Thanking you in advance, tx Kevin
Heart Rate Data in all Three Disciplines
Specifically designed for triathletes
Our smallest and lightest heart rate monitor (HRM)
Comfortable, easily adjustable strap
Stores and forwards heart rate data to your compatible device1
Enhance your triathlon experience by pairing HRM-Tri with your Forerunner® 920XT1. The HRM-Tri stores heart rate data when underwater, then forwards it to the device. Our smallest and lightest module fits within the width of the strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.
Running Dynamics
HRM-Tri also has an accelerometer in the module that measures torso movement to calculate 3 running metrics:2
Cadence — the number of steps per minute. It displays the total steps (right and left combined).
Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters). HRM-Tri is compatible with several other fitness products but will only display heart rate when paired.
Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
