The HRM-Run heart rate monitor provides the most advanced running metrics to high-end Garmin Forerunner® running watches. The strap is seamlessly comfortable and easily adjustable while the module is small, lightweight and fits entirely within the width strap.
HRM-Run provides 6 running dynamics metrics:
Cadence — number of steps per minute
Vertical oscillation — degree of ‘bounce’ in your running motion; displays the vertical motion of your torso, measured in centimeters for each step
Ground contact time — amount of time in each step that you spend on the ground while running; measured in milliseconds
Ground contact time balance — displays the left/right balance of your ground contact time while running (displays a percentage); for example, 53.2 with an arrow pointing left or right
Stride length — length of your stride from 1 footfall to the next; measured in meters
Vertical ratio — ratio of vertical oscillation to stride length (displays a percentage); a lower number typically indicates better running form
This real-time data can help athletes take their performance to the next level by showing them where they can improve their running form.

Very good product, the only thing I did not like is that they sent it to me in pink, I have no idea why, but the product is good

Reka - 07/12/2021
Perfect product, fast delivery. Very interesting to see the analytic data provided by the band. Comfortable and does not move during running.
Garmin hrm-run
Pascal - 06/12/2021
Very good product even if you need a flexible shoulder to put the attachment well. Cardio connection sometimes not immediate even if moistened beforehand. Metrics OK. On the Bikeinn website, the title (HRM 4 RUN) can be confusing. And delivery 2 days later than the longest time slot indicated.
Second purchase
McGoo - 26/11/2021
It would be better if the pod could be removable.

Pablo - 24/09/2021
It offers a large number of running metrics, ideal for analyzing your running dynamics down to the smallest detail. It also works very well for Garmin cyclocomputers, so you only need to have a cardio treadmill.

Lucile BANCAREL - 25/01/2021
perfect paired with the Forerunner 245 and the Garmin app! allows you to run cardio without difficulty and to analyze your race with your head rested. The belt is very easy to put on, does not slip and connects quickly to the watch I recommend
good addition to a Garmin watch
Gabor - 19/01/2021
Very accurate, much better than the wrist measurement. But as all such straps its a bit uneasy to wear, squeezes you chest, that is the price of the better measurements and cool stats.
Works
Aku - 14/01/2021
The heart rate is displayed accurately and more detailed running data is also used. The product was well packaged at the right price. The order lasted 1.5 weeks to Finland.

Upgrade needed
Roberto - 25/12/2020
Paired with the Garmin Forerunner 620 without any problems it was a pleasant and interesting upgrade to evaluate the posture and running dynamics.
Impeccable
Jéssica - 24/12/2020
Once again I was very happy with the purchase. Trusted site and very fast in sending the order. I had a problem (long delay) with the carrier, but the problem was not with the website. I asked here if it was compatible with my boyfriend's watch. They answered right away, taking all my doubts. I recommend !!

Very good product with perfect fit. I use it for both bike rides and running rides. The shipment arrived as established.
Great!
Andre - 05/08/2020
Great sensor, the best in comfort and precision
Good quality
Ricardo Nogueiro - 25/07/2020
I bought it because it had one from the decathlon that made me friction burns on my chest even using petroleum jelly, which in addition the band was always falling. With this one so far I am super satisfied, it is super comfortable and much softer, however I still use petroleum jelly to prevent burns. The only cons against it is that when it wears out you have to buy a completely new one, as you cannot enjoy anything since the cell is attached to the entire band.
Great
Alexandre Santos - 10/07/2020
Very accurate product, it should only go through water once a week, excellent
Much better than optical hr sensor
Dan - 26/06/2020
Better HR plotting and interesting running dynamics data.

Matti - 23/06/2020
Good product
Very Precise and complete
Razvan - 22/06/2020
Have used it at all my runs and is way more precise then the wrist HR monitor. The extra run dynamics are extremely useful too and help you improve your run form. Recommend to anyone wanting to be a better and faster runner.
Great HRM
Dor N. - 19/06/2020
This HRM from Garmin delivers its promise and works great for running with running dynamics metrics on supported devices as well as great on the bike or for indoor cycling.

Very easy to use instant pairing. Lots of very relevant new data The belt is easy to hang and you get used to it after one or two races.
Data richer
Christophe - 23/05/2020
Superb price / quality / webshop / delivery. Ant + coupling is quick and easy. Fit can be individually adjusted (even with a standard extension piece included). Start flawlessly and what extra data windows will appear .... Wonderful to not only exactly follow your stroke, but also your cadence, stride length, left-right, ground contact! Sold! Still hesitated with the HRM-tri, but for a runner, look no further.
Great !
Amoune - 22/05/2020
Very happy with my purchase, the 3rd on this site, always serious, very well packaged in terms of excellent traceability! The cardio belt is very nice also you can order with your eyes closed
