Marathon & half-marathon training
A training block that survives contact with reality
Every marathoner knows the plan on the fridge stops matching real life by week three. Runsy's plan moves when you do.
Long runs that grow safely
Your long-run progression is capped by your measured training load, so a missed week means a recalculated build, not a dangerous jump to catch up.

You do more than run. It counts.
Soccer on Tuesday. A ride on Sunday. 20+ minutes of another sport counts as a session, and hard sports count as intensity.
Garmin, COROS and Strava runs count when they sync to Apple Health.

FAQ
Fair questions
Will my Garmin, COROS or Strava runs count?
Yes, if they sync to Apple Health. Runsy reads those workouts from Apple Health, not through a direct Garmin, COROS or Strava integration.
How many weeks do I need to train for a marathon?
Typically 12 to 20 weeks, depending on your base. Tell Runsy your race date and it will tell you honestly what's achievable from your current volume, then build the safest path there.
Does it handle half marathons too?
Yes. Half marathon, 10K and 5K goals all work the same way: a periodized plan built back from race day, adapted weekly.
What if I get injured mid-block?
Tell your coach in chat. Runsy eases volume, swaps hard sessions for recovery, and rebuilds your remaining weeks around the setback instead of pretending it didn't happen.
Which devices does Runsy support?
Runsy is an app for iPhone and iPad, with an Apple Watch app that coaches your planned runs from the wrist. It builds your training from workouts and metrics in Apple Health. There is no Android app.
How much does Runsy Pro cost?
Runsy Pro costs US$12.99/month or US$79.99/year, with every feature on both plans. Your first week is free: you train with your coach for seven days before you're charged, and you can cancel in one tap before then.
How does the free week work?
Your first seven days are a free trial through the App Store. Two days before it ends, your coach reminds you with the date. Keep going and Runsy Pro renews at US$12.99/month or US$79.99/year; cancel before the trial ends and you pay nothing. Your plan and your runs stay either way.
What does Runsy read from Apple Health?
Workouts, including runs and other sports, heart rate, VO2 max, resting heart rate and body weight. These give your coach context for your training.
