Your personal science coach
Run your own pace.
Become a better you.
Better isn't only faster. It's healthier, more in tune with your own body, and still enjoying the run years from now — because the runners who keep going are the ones who run well. Paceriz does the math. It doesn't do the feeling: every call comes with its reason, so you understand yourself a little more each week.

🙋 I just finished a 14K LSD. How did I do?
Your pace today was around 6:10/km with an average heart rate of 158. Cardiac drift reached 38% — far above your usual −3%. That means even though it felt easy, your body was working significantly harder over the long distance. Tomorrow, keep it to 9K easy by feel — don't chase pace.
