Runna vs Garmin Coach is the question I'm asked more than any other, and it's a fair fight: one is the best free training platform in running, the other is the app I've trained with for over three years. I've used both, so rather than another comparison written from a spec sheet, here's how they actually stack up on price, watches, training plans, strength work and coaching, and which one you should choose.
Quick Answer Garmin Coach is the best free training plan available, but Runna is the more complete coaching experience. If you own a compatible Garmin watch and want structured training at zero cost, Garmin Coach is genuinely good and you should try it. Just know that Garmin's richer coaching extras, the additional expert guidance videos and AI insights, now sit behind its £6.99/$6.99 a month Connect+ subscription, so "free" no longer means the full Garmin experience. If you want deeper coaching, ultra distances, proper strength and Pilates programming, audio coaching and access to real coaches, Runna is worth the subscription. You can test it free for 2 weeks with code ANDY2: web.runna.com/redeem?code=ANDY2
3 Key Takeaways
Price vs depth. Garmin Coach's training plans are free, including the adaptive marathon plans, but Garmin now has a paywall of its own: the enhanced coaching content, extra expert guidance videos and AI insights require a Connect+ subscription at £6.99/$6.99 a month. Runna costs £99.99/year (UK) or $119.99/year (US) with everything included: strength, Pilates, mobility, audio coaching, AI feedback and in-app access to a human coaching team.
Hardware decides for many runners. Garmin Coach only works with a compatible Garmin watch. Runna works on any phone and syncs with Garmin, Apple Watch, Coros and Suunto. If you don't run with a Garmin, the decision is already made.
They adapt differently. Garmin Run Coach adjusts your training daily using physiological data: sleep, heart rate variability, recovery and training readiness. Runna adapts to your actual workout performances and life changes, with progressive pace targets, illness and holiday modes. Neither approach is wrong, they simply coach from different data.

Who Am I to Compare These Two?
I'm Andy Hood, an ultra-endurance runner from North Devon and a Runna Ambassador. I'll declare that upfront, because you deserve to know it before you read a word of comparison. What I'd also say is this: I've been training with structured plans for years, I've followed Garmin's adaptive suggestions through recovery blocks, and Runna has been central to every training block I've done since 2022. It helped me bring my marathon PB from around 3:45 to 3:20 and complete multiple ultras, including the Tour du Mont Blanc twice.
This comparison is written to be genuinely even handed. Garmin Coach deserves real credit, and there is one area where it clearly beats Runna. I'll tell you exactly where.
What Is Garmin Coach?
Garmin Coach is a suite of free, adaptive training plans built into the Garmin Connect app. For runners, it comes in two flavours.
Expert coach plans. You pick one of three named coaches, each with a distinct philosophy: Olympian Jeff Galloway (run-walk method, ideal for beginners and injury prevention), physiologist Greg McMillan (pace-based, performance focused) or physical therapist Amy Parkerson-Mitchell (gradual build with cross-training). These plans adapt to how your training is going and include video tips from your chosen coach. Worth knowing: the fastest goal pace is 7:00 per mile, so they're aimed at beginner to intermediate runners.
Garmin Run Coach. This is the newer, smarter option and the closest thing to Runna in Garmin's ecosystem. It builds a personalised plan around your race or goal, then adjusts your daily workouts using the physiological data your watch collects: VO2 max, lactate threshold, sleep quality, stress, recovery and training history. Slept badly and under-recovered? Expect a lighter day. Full marathon support was added in late 2024, closing what was previously Garmin Coach's biggest gap.
Everything syncs to your wrist, the watch guides you through each interval with vibration alerts, and it costs nothing. There's an optional Garmin Connect+ subscription (£6.99/$6.99 a month) that adds extra coaching videos and AI insights, but the coaching itself remains completely free, and after more than a year Garmin has kept its promise not to paywall it.
What Is Runna?
Runna is a dedicated running coaching app, founded in the UK in 2021 and acquired by Strava in April 2025 (the apps remain separate for now). It builds a personalised plan around your goal race, current fitness, and the days you can actually train, then guides you through every session with real-time audio coaching and pace targets.
Plans run from 6 to 26 weeks and cover everything from a first 5K to ultramarathons up to 50km. Alongside the running, Runna offers four types of supporting work: strength training (bodyweight through to full gym), yoga, a 26-session Pilates programme built for runners, and Stretch & Stability sessions. After each workout, AI-generated feedback shows you how well you executed the session, and you can message the Runna coaching team directly in the app.
Runna costs £15.99/month or £99.99/year in the UK, and $19.99/month or $119.99/year in the US. The standard free trial is 7 days, but code ANDY2 doubles it to a full 2 weeks with every feature unlocked.

Price and Value
There is no contest on headline price. Garmin Coach's plans are free, all of them, including the adaptive Run Coach and the marathon plans. If you already own a compatible Garmin watch, you can start a structured, adaptive training block today for nothing. For a runner unsure whether structured training is even for them, that zero-cost entry point is a genuinely brilliant place to start.
The caveat is that Garmin's "free" now has an asterisk. Since March 2025, the enhanced coaching layer, the extra expert guidance videos for Coach plans and the AI-powered Active Intelligence insights, sits behind the Connect+ subscription at £6.99/$6.99 a month (£69.99/$69.99 a year). The plans themselves remain free and Garmin has kept its promise not to paywall existing features, but if you want Garmin's fullest coaching experience, you're now paying £69.99 a year, which is within touching distance of Runna's £99.99.
Runna's £99.99/£15.99 (or $119.99/$19.99) has to justify itself, and it does so with breadth and the fact that one price includes everything: the strength and Pilates programming, audio coaching, AI feedback, ultra plans and coach access are all things Garmin Coach doesn't offer at any price. Compare it instead to what a single session with a human running coach costs and the annual plan looks like strong value. If you're already a Strava subscriber, the Strava + Runna annual bundle (£119.99 UK / $149.99 US) is worth checking too.
The hidden cost cuts the other way as well. Garmin Coach is "free" only once you've bought a Garmin watch, which starts around £150 and climbs well past £600. Runna needs nothing but your phone.
Winner: Garmin Coach for pure price. Runna for what you get per pound.
Watches, Phones and Compatibility
This is the simplest section of the whole comparison. Garmin Coach requires a compatible Garmin watch. It doesn't run on Apple Watch, Coros, Suunto or anything else, and even some older Garmin models miss out, so check Garmin's compatibility list before assuming yours qualifies.
Runna is watch-agnostic. It syncs sessions to Garmin, Apple Watch, Coros and Suunto so you can run straight from your wrist, phone-free, and if you don't run with a watch at all, the app itself guides you with audio through your headphones. I run with an Apple Watch Ultra 3 and Shokz OpenRun Pro 2, and the experience is seamless from start to finish. That setup simply isn't possible with Garmin Coach.
Winner: Runna, comfortably.
Training Plans and Distances
Both platforms now cover 5K through to the full marathon, and both build the plan around your goal date and available training days. Garmin's expert plans add the reassurance of named coaching philosophies, and the Galloway run-walk option is a lovely touch for new runners.
Runna goes further at both ends. It caters from complete beginner up to elite ability levels, builds custom plans for any distance from 5 to 50km, and is the only one of the two with proper ultramarathon plans. I've used Runna to train for 100K, and while the biggest 100-mile events may need supplementary planning, it handles serious volume well. Garmin counters with breadth of a different kind: if you also cycle or race triathlon, Garmin Coach has dedicated adaptive plans for those, where Runna remains running-only.
Winner: Runna for runners, especially beyond the marathon. Garmin if you're multisport.
How the Plans Adapt
Here's the most interesting difference between the two, and the one area where I'll happily say Garmin beats Runna.
Garmin Run Coach adapts daily using your body's data. Because your watch is tracking sleep, heart rate variability, stress and recovery around the clock, the plan responds to how ready you actually are. Poor night's sleep and high stress? Tomorrow's session eases off. That's proper physiological coaching, and regular readers will know it's exactly the kind of heart-rate-aware guidance I've been asking Runna to build. The trade-off is that it only works if you wear your Garmin day and night, and the plan can feel like a black box: you can't see far ahead because it hasn't decided yet.
Runna adapts to your performances and your life. It monitors how closely you hit each pace target and nudges your targets progressively, the same progressive overload principle a human coach applies. Where it shines is flexibility around real life: drag-and-drop rescheduling, B races built into your block, a "not feeling 100%" flag that restructures your remaining weeks around illness, and a holiday mode that builds a lighter week around time away. I use those features more than I'd like to admit, and they're the reason my training survives busy months.
Winner: Garmin for physiological intelligence. Runna for real-life flexibility. Honours even, and it depends which matters more to you.
Strength, Core, Pilates and Mobility
As a runner now in my fifties, I'd argue this section matters as much as any of them, because strength and mobility work is what keeps you training consistently and injury-free.
Garmin added supplemental strength to its Run Coach plans in late 2024. It's a toggle: choose bodyweight or full gym, and strength sessions are woven into your running week with exercise demos on the watch and in the app. It's a solid addition and better than nothing by a distance. What Garmin doesn't offer inside a running plan is dedicated core, Pilates or mobility programming.
Runna treats this as a first-class part of training. You get structured strength sessions (up to four per week, built around whatever equipment you have, from nothing to a full gym, with rep and weight logging), a progressive 26-session Pilates programme designed specifically for runners, yoga, and Stretch & Stability sessions for mobility and injury prevention. All of it is scheduled into your calendar automatically alongside your runs. In my experience the strength and mobility work has been as important as the run sessions themselves in keeping me consistent across long training blocks.
Winner: Runna, clearly.
Coaching, Feedback and Support
During a run, Garmin gives you watch alerts: vibrations and on-screen targets for each interval. Runna adds real-time audio coaching through your headphones, telling you when to speed up, slow down and when each segment begins. For structured sessions, that means you can run by feel and let the audio bring you back on track, rather than staring at your wrist.
After a run, Runna's AI feedback breaks down how you executed against each target, which has noticeably improved my pacing discipline over three years. And if you have a question, you can message Runna's coaching team in the app; in my experience the replies arrive within a day or two and are thoughtful, not boilerplate. Garmin has no equivalent human support for training questions, and its deeper coaching content sits behind the optional Connect+ subscription.
Winner: Runna.
Which Should You Choose?
Choose Garmin Coach if:
You already own a compatible Garmin watch and wear it day and night
You want structured training at zero cost, or you're not yet sure structured training is for you
You're a beginner-to-intermediate runner targeting 5K to marathon
You love the idea of a plan that responds to your sleep and recovery data
You also train for cycling or triathlon
Choose Runna if:
You run with an Apple Watch, Coros, Suunto, an older Garmin, or no watch at all
You want strength, Pilates and mobility properly programmed into your week
You're training for an ultra, or you're an advanced runner chasing quick times
You value audio coaching, post-run feedback and access to real coaches
You want a plan that bends around illness, holidays and real life without falling apart
My Verdict
If I owned only a Garmin and had no budget for training apps, I'd use Garmin Coach without hesitation and I'd expect to improve. It is the best free training platform in running, and the physiological adaptation in Garmin Run Coach is something I genuinely wish Runna would match.
But after three years, multiple ultras and a 25-minute marathon PB improvement, Runna remains my training platform, and this comparison explains why. It coaches the whole runner: the runs, the strength, the mobility, the pacing discipline, and the messy reality of a training block that has to survive work, illness and life. Garmin Coach gives you a very good plan. Runna gives you a coach.
The good news is you don't have to take my word for either. Garmin Coach is free to try today if you have the watch. And Runna's trial, extended to a full two weeks with code ANDY2, gives you complete access to everything with no features locked. Run both for a fortnight and you'll know.

Is Garmin Coach really free?
Yes. All Garmin Coach plans, including the adaptive Garmin Run Coach and its marathon plans, are free within the Garmin Connect app. The optional Garmin Connect+ subscription (£6.99/$6.99 a month) adds extra coaching videos and AI insights, but the training plans themselves cost nothing.
Does Garmin Coach work without a Garmin watch?
No, not in any meaningful way. Garmin Coach lives inside Garmin Connect and requires a compatible Garmin device to guide your workouts and, in the case of Garmin Run Coach, to collect the health data the plan adapts to. It does not work on Apple Watch, Coros or Suunto.
Does Runna work with a Garmin watch?
Yes. Runna syncs structured workouts directly to Garmin watches, as well as Apple Watch, Coros and Suunto, so you can follow your session from your wrist and leave your phone at home. Plenty of runners use Runna plans on Garmin hardware, taking Runna's coaching and Garmin's tracking together.
Which is better for marathon training, Runna or Garmin Coach?
Both now offer full marathon plans. Garmin Run Coach added the marathon distance in late 2024 and adapts daily to your recovery data. Runna's marathon plans add strength, Pilates and mobility sessions, audio-coached workouts and post-run feedback. I used Runna to bring my marathon PB from roughly 3:45 to 3:20. For a first marathon on a budget with a Garmin on your wrist, Garmin Coach is a solid choice; for the most complete preparation, I'd pick Runna.
Does Garmin Coach include strength or core training?
Partially. You can toggle supplemental strength workouts (bodyweight or full gym) into a Garmin Run Coach plan, which is a genuinely useful addition. There is no dedicated core, Pilates or mobility programme within the running plans, which is where Runna's 26-session Pilates programme and Stretch & Stability sessions pull ahead.
Can Garmin Coach train me for an ultramarathon?
No. Garmin Coach running plans top out at the marathon. Runna builds plans for any distance up to 50km, and I've used it successfully for 100K training, though the very biggest ultra distances may need some supplementary planning.
How much does Runna cost in the UK and US?
In the UK, Runna costs £15.99 per month or £99.99 per year. In the US, it's $19.99 per month or $119.99 per year. A Strava + Runna annual bundle is also available (£119.99 UK / $149.99 US). Prices can change, so check the app for current pricing in your region.
Is there a Runna free trial?
Yes. The standard trial is 7 days, and referral code ANDY2 extends it to a full 14 days with every paid feature unlocked. Enter the code during setup or use web.runna.com/redeem?code=ANDY2. You can cancel any time before the trial ends via your device's subscription settings and pay nothing.
Can I use Runna and Garmin Coach together?
Not really. Your watch can only follow one structured plan at a time, and running two competing plans would double your training load. What you can do is use Runna as your coach while a Garmin watch handles the tracking, keeping Garmin's health metrics, VO2 max and recovery data alongside Runna's plan.
Did Strava buy Runna?
Yes. Strava announced the acquisition of Runna in April 2025. The two apps continue to operate separately with their own subscriptions, though a discounted joint Strava + Runna annual subscription is now available.
Happy running.
