Runsy

Answer a few questions and Runsy builds your first week in seconds, working back from your race date through base, build, peak, and taper.

The plan reshapes itself around your logged runs, Apple Health data, and schedule, so a missed session is made up rather than lost.

Type or send a voice note to your coach to swap sessions, add a rest day, or adjust a workout, and it tells you exactly what changed.

Runsy predicts your 5K, 10K, half marathon, and marathon times, and reads VO2 max, resting heart rate, and heart rate zones from Apple Health.

You can see what your coach remembers about you and delete it, and check-ins respect quiet hours and frequency limits.
