Stryd is not all it's cut out to be...maybe

True. And Safe the Money or make sure that you know that you have to buy a measuring wheel.

You know what funny is everyone was talking about stryd how good it is and then I got one and I'm seeing these posts. From my experience it was short sometimes and other times it was better than gps. I guess it depends on the area. I don't find the GPS on the fenix 6 pro very good so got nothing to lose

According to the Stryd cult, Stryd is never wrong! It is always user error or the course has been measured incorrectly.  That's the mantra. 

LOL. It’s true. It’s even more worse:

My Marathon was way too short: 40.x k : No apologize. Nothing. Maybe the course is wrong. I mean. I told them: all my teammates using gps have an error around +-1 %. Answer: you need a calibration factor  

Ok. On the website and in the advertisement: Out of the box accurate.  

The funny thing: I went to a track: Again very bad results for Stryd. I have to use a factor. Fine. Support: Don’t trust tracks because these could have the wrong length 

Ok. It was working. Still varying but it was not more worse than GPS.
then I used my second pair of shoes: Again: Bad results. Again on the same track: And: True. Different result for the factor.

I am done with the great out of the box accuracy. I save my time on that: GPS is fine

I was so disappointed with a Stryd I bought couple of months ago that I sent it back to save my money while I could. The problem was that it measured differently depending on the shoes I was wearing. No matter how I changed the placement it did not improve. The difference was 12.0k with one pair vs 12.4k with other vs 12.7k with GPS. I was not happy with such discrepancies between running shoes and especially if I was thinking about 25-30k long runs (while I can accept a difference with GPS).

By the way, if you live and buy Stryd in Europe like I do and want to return the Stryd (bought on the official web site), they make you send it over to US! That gave me a hell of a headache and that’s something they don’t mention anywhere when you make the initial purchase.

Funny, over in this thread people are complaining about GPS inaccuracy much worse than what you’re describing:

It seems the grass is always greener on the other side of the fence. But good to hear you found a solution you are happy with.

It was the best decision. Maybe I will sell mine too

I also generally see changes in both pace and power when I change shoes.

Today I wore a new set of shoes, and used 2 Stryds. Today when the first Stryd reported 1 mile, it was another 2 seconds of running before the the 2nd Stryd gave its 1st mile alert. But this actually is quite usual, the 2nd Stryd always comes up shorter and both are still short compared to actual, but no obvious change this time around, presumably because the stack height and heel drop are similar?

However POWER is much much closer between the models now, often I saw big differences of 30W+ which I've shown here before, the gap has closed significantly it seems, usually no more than 10W difference and often closer to 5W (with a couple of exceptions)

Stryd is imperfect. This same statement applies to every stride sensor, and every GPS device, ever created. If perfection is your expectation, I would suggest running by time and perceived effort, and put pace and distance aside.

The question is not, is it perfect?, but is it better?, or does it offer more? 

I have used every stride sensor from the original Polar twinkie, through multiple other polar and garmin sensors, to the current model Stryd.

ALL stride sensors will have slightly varying accuracy between various shoes, and between various paces. Stryd is by far the best of the on-shoe sensors I have used. Stryd is within 1% for me between shoes, and better than that between paces. I simply calibrate for each pair of shoes, and have a dedicated racing pair that I calibrate at race pace or close to it. 

The choice for me is between Stryd, which is 99%+ accurate with usable instant pace, or GPS, which has completely unusable instant pace, lacks better accuracy for distance, and has the additional possibility of completely crapping its pants on any given day and being horrible. For those that choose it, there is also the option of GPS for distance, and Stryd for pace. 

I get it that some users do not have as positive experience with Stryd as I have, but I personally don't see any better alternatives out there.
