No.
Running power provides numbers that 𝑟𝑒𝑝𝑟𝑒𝑠𝑒𝑛𝑡 your effort.

No, as long as the numbers are repeatable and valid:
🔹 Repeatable? The same effort under the same conditions gives the same result.
🔹 Valid? The numbers are highly correlated to an existing ‘gold standard’.
The Stryd footpod has been independently validated and found to produce repeatable numbers that are highly correlated with O2 consumption (a gold standard for measuring exercise energy consumption).
Wrist-based power has not been independently validated. However, I ran my own (N=1) study during 2024 and 2025, comparing wrist-based power from Garmin, Coros and Apple to Stryd. I found they produce repeatable numbers that, for most recreational runners, are correlated to the Stryd footpod.

Far from it.
Running power numbers CAN be used as a measure of how hard you’re working when you run.
And once you can measure your effort, that’s when the real magic begins.
