Start where you are
Your plan, one day at a time
Tell it your race, race date, where your running is today and the days you can train. It builds a week-by-week plan from foundation to race day, and tells you straight away if the date is tight.
Everything between here and the finish
Run. Walk. It tells you when.
Coached on the run
Rising beeps mean run, falling beeps mean walk, with a voice that says what's next and a 3-2-1 before each switch. Works over your music with the phone locked.
Apple Watch
Run from your wrist with taps, beeps, heart rate and GPS, and leave the phone at home. Workouts save to Apple Health.
When life happens
Missed a week or got sick? Repeat a week, push the plan back or rebuild from today, always keeping your race date.
Race day, already planned
A rough finish time, the pace you need for the cutoff, a fuel schedule, a kit checklist and how to run the day.
Treadmill, trails and hills
Treadmill mode without GPS, weekly climbing targets for hilly races and hike/run mode. Eating reminders on long runs.
Strength that fits
Optional short sessions for knees and hips: gym, dumbbells or bodyweight. Switch it off and the plan is running only.
Built for bigger runners
Gentler build. More recovery. Same finish.
Most training plans assume a light runner. Turn on joint protection and your joints get the time to adapt that your heart and lungs don't need.
- Longer walk breaks to start
- A slower weekly build, about 6% instead of 10%
- A lighter week every third week
- One run a week swapped for low-impact cardio, like a bike or elliptical
Recommended above about 220 lb (100 kg), or with past shin, Achilles, foot or knee trouble.
