Train with
your body,
not against it.

Phaes times your training to your menstrual cycle, through perimenopause and beyond. Track your symptoms, spot your patterns, and feel like yourself again.

Loved by runners training in rhythm, not in spite of it.

Perimenopause changes the rules. Not your finish line.

Shifting hormones, restless sleep, and energy that won't hold still can make running feel like a stranger's body. Phaes reads the change, adapts your training to how you actually feel, and helps you train strong through it, so you can feel like yourself again.

Energy that swings

Some weeks you feel unstoppable, others a recovery jog feels brutal. Phaes adapts the plan to the body you have today.

Cycles that wander

Late, long, or skipped. Phaes works from how you actually feel, not a textbook 28-day calendar.

Strength that lasts

Smarter load, real fueling, and proper recovery protect your bones, muscle, and the runner you have always been.

Your cycle is a training signal.

Hormones swing across four phases, and so does your strength, recovery, and how hard a run feels. Log your symptoms each day and Phaes maps the patterns, so your training moves with your body instead of fighting it. Tap a phase to explore it.

Days 6 to 13

Build your base.

Estrogen climbs and so does your appetite for work. Your body recovers fast and adapts well to load.

Train

Stack your volume and hardest quality sessions.

Fuel

Plenty of carbs to back up the bigger weeks.

You can't out-train an empty tank.

Training is only the stimulus. Food is the adaptation. Phaes pairs every plan with phase-aware fueling so progress actually sticks.

Fuel the work

Under-fueling is the hidden injury.

Not eating enough quietly wrecks bone density, hormones, and performance. Phaes flags the gap before it costs you a season.

Protein first

Protein builds the runner.

Every easy mile and hard session creates tiny muscle damage. Protein is what rebuilds it stronger, and most runners eat far too little.

Carbs = speed

Carbs aren't the enemy.

Your hardest sessions run on glycogen. Phaes scales carbs to the week ahead so the fast days feel fast.

Recover right

Recovery starts on the plate.

Sleep, hydration, and smart timing turn a hard run into real adaptation, especially in your luteal phase.

A coach in your pocket that listens.

Phaes is built for the messy reality of training around life. Three steps to start, then it keeps up with you.
