Why Runsy
Never run before? Perfect.
Classic Couch-to-5K programs assume every week goes to plan. Real life doesn't work that way — and that's exactly what Runsy is built for.
Start where you are
Your first workouts mix short runs with walking breaks at a conversational effort. If a run feels too hard, tell your coach — the next one gets easier.
Life-proof progression
Sick week? Work exploded? Runsy rebalances your plan instead of resetting it. You keep your progress, and the path to 5K just bends a little.
A coach for the questions you're embarrassed to ask
"Is it normal to be this out of breath?" "Do I need special shoes?" Ask anything in chat — no judgment, answers based on your actual runs.
How it works
Coaching, not templates
01
Tell Runsy your goal
Your first 5K, a marathon PR, or just running consistently. Two minutes of questions — no fitness test, no jargon.
02
Get a plan that starts where you are
Brand new? Runsy starts you safely from zero with walk-run workouts. Already running? It reads your Apple Health history — pace, distance, heart rate — to set a starting point that's yours.
03
Watch it adapt, week after week
Miss a run, say something aches, crush a workout — your plan rebuilds around what actually happened, and your coach tells you why.
The Runsy difference
Life happens. Your plan keeps up.
Static plans die the first week something goes sideways. Runsy expects it — your plan revises every week, and rebuilds the moment you miss a run or say something aches.
- Miss a day — the week rebalancesYour harder session moves, an easier day slots in, and the progress you earned stays put. No restart, no catch-up cramming.
- Feel beat up — volume eases firstMention soreness and Runsy backs off before a small ache becomes an injury. Progression is capped at safe weekly growth.
- Get faster — paces update themselvesEvery synced run refines your paces. The plan you see tomorrow already knows the run you did today.
Coach chat
Ask anything. It remembers everything.
Pacing, soreness, race strategy, or the questions you'd be embarrassed to ask a human — your coach answers from your full training history, and turns the conversation into plan changes.
Grounded in you
Built on your numbers, not a template
Runsy measures your real walking and running — volume, pace, and training load, the same overtraining early-warning signal used in sports science — and keeps progression gentle: roughly 10% a week at most, never two hard days back to back.

FAQ
Fair questions
How long until I can run a 5K?
Most beginners get there in 6–10 weeks. Runsy sets the timeline from your starting fitness and adjusts it as you go — some people need longer, and that's built in, not a failure state.
What if I can't run for even a minute?
That's a normal starting point. Your first sessions are mostly walking with short jogging pickups, and they only get harder as your body shows it's ready.
Do I need an Apple Watch to start?
No — your iPhone is enough. If you do wear a watch, your runs sync automatically through Apple Health and make your coaching sharper.
I'm really out of shape. Is this safe?
That's exactly what Runsy is built around. Your first sessions are mostly walking at an effort where you could hold a conversation, and progression is capped — volume grows about 10% a week at most, never two hard days in a row. If you have a medical condition or your doctor has raised concerns, check with them first — then Runsy meets you where you are.
How do I know when to run and when to walk?
Every workout spells it out — run 1:00, walk 1:30, repeat ×8 — right on the workout screen, so there's no counting in your head. And if an interval felt too hard, tell your coach and the next session adjusts.
Does it work with Apple Watch?
Yes. Runsy is built for iPhone and syncs through Apple Health, so runs recorded on your Apple Watch — or any app that writes to Apple Health — feed straight into your plan and coaching.
How much does Runsy Pro cost?
US$12.99 per month, shown in your local currency at App Store checkout. New subscribers get the first 7 days free with full access — cancel during the trial and you pay nothing.
How does the free trial work?
New subscribers get full access to everything for 7 days, free. After the trial, Runsy Pro continues at $12.99/month, auto-renewing. Cancel anytime in your App Store settings and you won't be charged.
