Stryd tracks your foot through three dimensional space and records the accelerations, impacts, and forces that are being applied. From that information, we calculate power, as well as provide other commonly used run metrics like distance, pace, cadence, ground contact time, vertical oscillation, etc. All of our calculations have been validated with high resolution motion capture systems, dual force plate treadmill, and metabolic testing.

But how does it calculate acceleration? This is only possible with two measures. Ok, you have the time and can determine the change of direction. But from my understanding in physics you need somehow the way/distance. Could you share those technical details?
