Fyi, make sure you set your height and weight correctly in the stryd powercenter before each use to get accurate power readings
STRYD actually state NOT to do this as it will invalidate your power numbers and CP.
I was told specifically to do this by stryd support, as weight is used in the power measurement...ill look into it
Yes, it's VERY important to get that info in, but if your weight is only shifting a few pounds +/- then you are invalidating your CP and zones calculations by changing your weight constantly. There are several posts by the STRYD rep in the Fb group that covers this.
From the STRYD support Fb page.....
"But what about weight? In outdoor cycling your true weight will determine how quickly you move forwards for any given force you put through the pedals. It is more complex than that, but again, it’s a reasonable simplification. There is no requirement to enter your user weight within your bike power meter, it simply measures force to display power. In running this is not the case. The Stryd pod needs user weight to be able to display power. It measures velocity and height changes to calculate W/kg, then takes user weight to display power.
So why is it not recommended to change Stryd weight as your true weight changes day to day? The Stryd eco system has been built around the 90 day power duration curve and critical power. Stryd watch apps display W, not W/kg. If you changed your Stryd weight each time your physical weight changed, when you then went for a run you would not know if your power changed because your speed changed, or just because your weight changed. Therefore to best make sense of running power it is recommended to give your Stryd weight constant, even if your physical weight changes."
