Most training plans are built on male physiology. Taperai combines your WHOOP biometrics with cycle-phase science so you peak on race day — not despite your biology, but because of it.
Your hormones shift your pain tolerance, your thermoregulation, your recovery capacity — every single week. A plan that ignores that isn't just suboptimal. It's working against you.
"I kept blowing up on race day and couldn't figure out why. Turns out my taper always landed in my luteal phase."
Estrogen rising. Higher pain tolerance, better power output. We maintain stimulus longer — your body can handle it.
Peak performance window. If race day falls here, minimal taper needed. We sharpen, not suppress.
Progesterone rising. Core temp elevated, perceived effort higher. We taper earlier and more aggressively.
Most variable phase. We prioritize sleep and stress reduction. That RHR spike is hormonal — not a fitness regression.
One-click OAuth. We read your recovery, HRV, sleep, and strain — nothing else.
Enter your race date and last period start date. We calculate your phase automatically and re-ask monthly.
Every morning you get an email: what to run, how hard, and why — adjusted for your biometrics and cycle phase.
First 100 runners get free early access access. No credit card, no commitment — just a taper plan that finally accounts for your whole biology.
