What it is

01

Tuned to your goal

A 16–24 week plan anchored to your race date, scaled to your goal time, shaped by how many sessions you can actually run. Every pace zone is calibrated — easy, marathon, threshold, VMA.

02

Yours, on your phone

No accounts. No ads. No analytics. No servers. The plan is generated on your device from a deterministic algorithm you could read end-to-end in an afternoon. Delete the app and nothing survives.

03

Honest about what you did

Connect Strava and every session shows planned vs actual — distance, duration, average pace. Add a note about how it went. The app never grades you; it just keeps the record.

How it works

  1. STEP 1

    Answer seven questions.

    Your last race, time off, race day, goal time, sessions per week, preferred long-run day. Five minutes, no sign-up.

  2. STEP 2

    Your plan generates instantly.

    Phases — base, build, peak, taper, race — laid out week by week with distance, duration and pace for every session.

  3. STEP 3

    Run. Log. Compare.

    Mark sessions done, sync Strava to see planned vs actual, journal what happened. Export a text copy or share the plan publicly if you want company.
