Function: Stryd Run Power Meter

"force x velocity = power"

Stryd Power Meter Features:

  • Integrated in HRM strap
  • Power (W), Heart Rate (bpm), run form
  • 6 month+ battery life and easy to replace
  • ANT+ & Bluetooth Smart connectivity

What Stryd says:

"The Stryd power meter enables runners to reliably measure their power output. The Stryd power meter enables runners to monitor and gauge the intensity of their training or competition much more precisely."

"With Stryd, runners can assess and track the improvement of their running efficiency in the field, outside of a lab setting."

What we say:

It had to happen, the implementation of a new metric for runners! The king, heart rate is about to get a viable contender challenging for supremecy!

So what is it? Looking like a regular heart rate strap it replaces your existing monitor that fits around your chest and syncs to your watch or smartphone. In my testing it was with a Polar V800 and a Garmin Fenix 2. Both brands are popular choices for the runner and triathlete. SUUNTO also are heavily involved but I didn’t have a unit available for testing but it looks like they are sitting alongside the other two brands with compatibility.

Linking to the watches proved as simple as getting ready for a normal run. You connect the Stryd unit to the heart rate strap and pair to the watch. There are short instructional videos on the Stryd website for most eventualities making it as easy as possible to see what to do.

There is one point I will make here, and I stress it will probably change very quickly via a firmware update but currently the watches on the market do not allow power as a running metric. Quite simply, you select a cycling mode on the watch and off you go, business as usual except you are recording in the cycle mode not running. So far my watches have recorded the training data with the only difference in the data is labelled as a bike ride. As I mentioned, this will no doubt be addressed by the watch brands very soon. It’s not a big deal as I now have power reading available as well as heart rate, cadence, studies per minute, temperature, altitude, GPS, need I go on?


So what is the point? Well, power is a more immediate metric. Take for example a runner using heart rate as a training parameter. All great, heart rate is a brilliant way to make sure you are training effectively and not piling up junk miles and getting the most from your run. Your runner is running up a hill, heart rate being measured and training intensity being monitored. When your runner hits the top of the hill the heart rate is still racing ahead even though the exertion has fallen off and the runner is still looking like they are working hard, even though the terrain has levelled out.

Power works differently.The Stryd power meter uses data from built in motion sensors, e.g. accelerometers and angle sensors as well as environmental sensors. This information is evaluated in regard to the runner’s weight and velocity to compute power in real time. In addition to common power metrics (current power, average power etc.) that are captured by cycling power meters, the Stryd running power meter also records running specific metrics such as the force of impact and the stride frequency.

When you hit the top of the hill your power reflects that change in situation far quicker than heart rate. Do not dismiss heart rate, this is still in the mix but can be utilised accordingly. As cyclists and triathletes who use a power meter on their bikes already know, power data allows a much more precise gauging of intensity during training and competition than heart rate data. You can see this in effect when you are out running. Power ranges dramatically as you walk, jog, run up a hill, run down a hill, it is all very obvious when you see it in action.


Analysing the data is possible via Stryd’s online platform. Stryd Powercenter serves as a data hub. It connects with Garmin Connect and Suunto Movescount, so it can stream data automatically to Stryd Powercenter. It connects with third party online training platforms, and can stream data to these platforms, Training Peaks, Strava, Xhale all utilise the power data. You can also download the phone app too for a full hand. The screengrab is from XHALE and you can see graphs for major metrics.


So is it worth it? Well, measuring power on the bike costs a lot more! The Stryd is far more affordable and if you are just a runner, those bike power meters are irrelevant anyway! Here we have a huge leap forward in training technology that works, is useful and has been made at a decent price. If you are a numbers geek, you will love it. If you want to maximise your training you’ll love it. If you simply need to replace your heart rate strap it’s worth a look. At the end of the day it won’t get you fitter by itself, you will still need to get out and run but if you can analyse more data then it must be worth it! Joking aside, this is a Stryd forward. Check it out very soon.
