RunRun training plans with a Coros, Suunto or Polar watch

RunRun training plans with a Coros, Suunto or Polar watch

Your runs flow back through Strava, today's session shows up in your calendar — and here, brand by brand, is what actually works to get it on your wrist

Build my free plan

One thing first, because most pages claim the opposite: as of September 2026, no consumer watch app imports a planned workout file. Not COROS Training Hub, not Polar Flow, not the Suunto App, not the Wahoo app — and not Garmin Connect either. Their "import file" button only exists to recover a run you already did. Better to say so now than let you hunt for a menu that isn't there. What does work, however, works beautifully: RunRun builds your plan, Strava brings your runs back to tick off your sessions, and your calendar puts today's workout in front of you — on your phone and on your watch. For interval sessions, your app's built-in workout editor handles the rest, once and for all.

Why choose RunRun?

A plan built around you

Goal, current level, available days: RunRun generates a complete plan — 5K, 10K, half, marathon or trail — with target paces, durations and recoveries for every session.

Your runs come back on their own

Coros, Suunto, Polar, Wahoo: every one of them syncs with Strava. Connect Strava to RunRun and each run ticks off the session you had planned, with nothing to type in.

Today's session in your calendar

RunRun publishes your plan as a calendar your phone reads natively. Today's workout reaches your wrist the same way your meetings do — whatever brand you wear.

Intervals, through your app's own editor

COROS Workout Builder, Polar Flow's phased targets, the Suunto App's "create structured workout": your app can build a structured session. RunRun gives you the blocks, you enter them once — and the workout stays in your library.

Paces calculated, not guessed

RunRun works out your target paces from your VO2max estimate or a recent race time, following established training-zone principles. The pace calculator is free to use, no account needed.

Free, no card required

Build your plan, connect Strava, sync your calendar: none of it costs anything, and nothing asks for a payment method to get started.

How it actually works

W1

Step 1 — Build your plan

On runrun.fr, enter your goal, your level and the days you can run. The plan appears with every session spelled out: type, duration, target paces, recoveries.

  • •Pick your goal: 5K, 10K, half marathon, marathon or trail
  • •Enter your level and weekly availability
  • •The full plan shows up straight away
W2

Step 2 — Connect Strava

This is the watch → RunRun direction, and it is automatic. Your watch already sends your runs to Strava; RunRun picks them up there and ticks off your planned sessions for you.

  • •Your watch syncs its runs with Strava, just as it always has
  • •In RunRun, connect your Strava account in one click
  • •Every run validates the planned session and feeds your stats
W3

Step 3 — Sync your calendar

This is the RunRun → you direction, and it works on every brand. RunRun publishes a calendar link; you add it to your phone's calendar and each session appears on its date, in full detail.

  • •Copy the calendar link from your RunRun account
  • •Add it to your phone calendar (iPhone, Android, Google Calendar…)
  • •Today's session shows on the phone — and on the watch that mirrors it
W4

Step 4 — For intervals, prepare the session in your app

An easy run works fine with the session simply in front of you. A 6 × 800 m does not: open your app's workout editor and copy in the blocks RunRun shows you. It's a one-off — the workout then lives in your library and can be started again any time.

  • •Coros: COROS app or Training Hub → Workout → create the session
  • •Polar: Polar Flow → phased training target → save as favourite
  • •Suunto: Suunto App → "+" → create structured workout

Five tips to get the most out of RunRun with your watch

1

Only structure what deserves it

Easy runs and long runs need no programmed workout at all: a duration and a target pace are enough, and your calendar reminds you of both. Save your app's editor for block sessions — intervals, threshold, hills.

2

Build yourself a library

The sessions in a plan come round again and again. Save them once in your app (COROS workout library, Polar Flow favourites) and you'll never have to recreate them.

3

Check kilometres versus miles

RunRun gives paces in min/km. If your watch is set to miles, the pace alerts won't line up. It takes seconds to change in the app.

4

The FIT/TCX file is still there — for other uses

RunRun can always export a session as FIT or TCX. That file won't go into your watch's app, but it feeds third-party tools such as intervals.icu, it archives your plan, and it can be copied onto a Garmin over USB.

5

Got a Garmin? Different story

Garmin is the one brand RunRun can send workouts to directly: connect your account and they land on the watch with nothing to do. The file becomes pointless at that stage.

Can I import a RunRun workout file into COROS Training Hub, Polar Flow or the Suunto App?
No, and that isn't down to RunRun. These apps do accept .fit and .tcx files, but only as completed activities, to recover a run that wasn't recorded. None of them offers an "import a planned workout" function — with Polar, Flow's import only handles routes. The path these brands intend for structured sessions is their own editor, or a sync with an approved partner.
So how do I get my RunRun session onto a Coros, Suunto or Polar watch?
Two complementary routes. Calendar sync puts today's session and its full detail on your phone, and therefore on your watch — instantly, on every brand. And for block sessions, your app's built-in editor (COROS Workout Builder, Polar Flow phased targets, Suunto App structured workouts) lets you enter the intervals RunRun gives you once, then rerun them whenever you like.
What about a Garmin?
Garmin is the one case where RunRun pushes the session directly: connect your account and it shows up on the watch, no file, no fiddling. Worth noting, because it surprises people: Garmin Connect doesn't import workout files either — its import is for activities. The only other route is plugging the watch in over USB and copying the .fit file into the GARMIN/NewFiles folder.
Does it work with Wahoo?
Your runs come back into RunRun through Strava and your calendar shows your sessions, just as with the other brands. That said, Wahoo is the most closed ecosystem of the lot for structured workouts: no file import and no built-in editor. Planned workouts can only reach it from a third-party provider Wahoo has authorised.
What is RunRun's FIT / TCX export for, then?
Three things: feeding third-party analysis tools that do read structured workouts (intervals.icu, for instance), keeping a readable archive of your plan, and loading a session onto a Garmin by USB copy. We would rather say so plainly than imply a universal compatibility that doesn't exist.
Do I need a RunRun account?
Yes, to generate a plan, connect Strava and sync your calendar — it's free, no card, and takes under two minutes. The pace calculator itself works without an account.
Why does this page contradict what I read elsewhere?
Because a lot of pages repeat an assumed compatibility without checking it. Everything above was verified on 23 September 2026 against each brand's official documentation. If one of these apps ever opens up workout import, this page will be corrected — and the feature added to RunRun.

Your training plan, your watch, no empty promises

Create your free account, generate your plan, connect Strava and sync your calendar. Five minutes and your training is set up — whatever watch you run with.
