Find your training paces in 10 seconds
Enter one recent race. We estimate your running fitness and the exact paces to train at — then AISRi adapts them every day to your sleep, HRV and fatigue.
Recent race result
Built on proven running-physiology models. A static calculator gives you these once. AISRi recomputes them after every run, only unlocks pace targets once your HR has settled, and freezes intensity when your recovery says so.
Why AISRi
Not a pace calculator. A coaching system.
A pace table is a great place to start. Here's where it stops — and where AISRi keeps going.
Pace-table apps
Genuinely useful — they're free, instant, and the VDOT science behind them is sound. For a quick goal pace, most runners start here. So did we.
Where they stop
AISRi · 6-Pillar System
Everything a pace table gives you — plus a system that reads your body and adapts the plan every day.
“A pace table tells you your pace today. AISRi tells you who you're becoming.”

Cardiac Output
Stroke volume, long-run HR drift, decoupling
Recovery Capacity
HRV, sleep quality, TSB, freeze gate
