THE PRODUCT

A real week, inside the app.

From plan to adjustment — see exactly what you find when you open Rai.

App screen showing the week's planned workout and the half marathon goal

Your plan, always in view

Every week already shows today's workout, your race goal, and the days left — no digging required.

App screen detailing a workout's structure with heart rate zones

Every workout, with a purpose

Heart rate zone, target pace, and the reasoning behind each block — Rai explains before you head out.

Chat conversation with Rai assessing whether a target pace is achievable

A coach that doesn't just agree

Ask anything. Rai answers based on your real data — even when the answer is "ambitious, but possible."

Statistics screen showing estimated VO2 and race time predictions

Your progress, in numbers

Estimated VO2 and race predictions, updated with every run logged.

WHAT NO SPREADSHEET DOES

Your plan doesn't sit still.

With every run you log, Rai re-reads your data and recalculates what comes next. You don't have to ask.

You run
The workout arrives from your watch, or you mark it complete in the app.
Rai reads the data
Pace, heart rate, distance — and how you said the run actually felt.
The plan adjusts
Load, paces and days shift to match your real week, not the ideal one.
The next workout is ready
With the reason for the change explained, so you know what you're doing and why.

Chat conversation where the runner asks to move the day's workout and Rai confirms the reorganized week

One request in plain language. Rai reschedules the workout and reports what changed across the week.

Build your plan and watch it adapt to your routine.

WHO TRAINS YOU

A coach, not a spreadsheet with a chat box.

Rai has a name, a method and an opinion. She follows your week, comments on your workouts and answers from your data — not from canned phrases.

She looks at your week
Every Sunday Rai sums up what happened and what it means for your goal.
She pushes back when needed
If your goal doesn't match your numbers, she says so — and explains what's missing to get there.
She's available 24/7
Questions about pace, pain, shoes or race strategy: just ask, any time.

App screen with Rai's weekly insight about the taper week and the previous week's summary
