I suspect that Stryd is providing remarkably accurate elevation information. Depending on the watch, the data from Stryd can be combined with the Watch's GPS data so that Stryd gives distance and pace, and the watch's GPS can be used for navigation.) (Stryd doesn't use or provide GPS data, it uses accelerometers. I think that this feature alone makes the Stryd good value for money. This accuracy is also reflected in its measurement of current running pace. (It's possible to tweak the accuracy with calibration, but out of the box is should be much better than GPS.) If you look at my testing of distance accuracy you'll see that the Stryd is right at the top of the chart, and is far more accurate than any GPS device I've tested. It's the only Footpod that is accurate enough that it doesn't require calibration, something that greatly improves its usability. My testing has shown that the Stryd is stunningly accurate in its measurement of distance. Stryd provides an array of different metrics, which vary both in accuracy and usefulness. 18.6 Suunto Ambit3 (all models), Ambit2 R.18.3 Garmin 920XT, Vivoactive, Vivoactive HR, 235.17 Stryd's Power Estimate Compared with Cycling Power.11.3 Accuracy and Consistency at Different Paces.At $220 I think that Stryd is good value for money, and it's one of the few running devices that I would replace unhesitatingly if I lost it. While I believe Running Power Meters are quite different to cycling power meters and are more of a 'power estimate' than a meter, I think that Stryd's power estimate has improved to the point where it's a valuable training and racing tool. It accurate enough that it really doesn't need any calibration, and unlike GPS, it should work in any situation (see below for details.) Not only is it providing accurate distance measurement, but it provides real-time pace, something that's impractical to achieve with any GPS device.

If you look at my testing of GPS Accuracy, you will see that Stryd gives a far more accurate measurement of distance than any GPS watch. While a lot of the Stryd marketing focuses on their 'running power meter' functionality, I see the greatest value coming from their accurate measurement of pace and distance. It's a Footpod that analyzes the movement of your foot with greater accuracy than most traditional Footpods, and with vastly greater accuracy than GPS. Stryd is one of the most useful and impressive running technologies available.
