Why Runsy
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 is alive — it moves when you do.
Periodization done for you
Base, build, peak, taper — structured from your race date and current weekly volume, with recovery weeks placed before you need them.
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.
Race-day answers from your own data
Goal pace, fueling cadence, taper doubts — ask your coach. Its answers come from your runs, your paces, and your race date.
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 continuously measures your real volume, paces, and training-load ratio — the same acute-to-chronic signal used in sports science — and keeps progression inside safe bounds: roughly 10% a week, never two hard days back to back.

FAQ
Fair questions
I run with a Garmin, COROS, or Strava — will my runs count?
Yes — as long as they reach Apple Health. Turn on Apple Health sync in your device's companion app (Garmin Connect, COROS, or Strava) and every run flows into Runsy automatically.
How many weeks do I need to train for a marathon?
Typically 12–20 weeks depending on your base. Tell Runsy your race date and it will tell you honestly what's achievable from your current volume — and 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.
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.

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.
