If you’re a coached endurance athlete, there’s a good chance your entire training history lives within TrainingPeaks. And that just changed ownership.

Garmin announced this morning that it has acquired TrainingPeaks and TrainHeroic, the two dominant platforms for structured coaching in endurance and strength sports.

The deal brings roughly 120 employees from Louisville, Colorado-based Peaksware Holdings into Garmin’s workforce. Financial terms weren’t disclosed.

But this is big and made us say, whoa. Definitely bigger than a typical acquisition headline, because of what TrainingPeaks has always represented to this sport: neutral ground.

Why This One Hits Different

TrainingPeaks wasn’t built as a Garmin product. It was built as everyone’s product. Coaches running athletes across Garmin, Wahoo, Polar, Coros, and Suunto hardware could plan a single training calendar and have it sync everywhere. That agnosticism is the entire reason a coach with a mixed roster could run their business on one tool. TrainHeroic did the same thing for strength and conditioning coaches.

Now the company that makes one of those watches owns the platform that was supposed to treat all of them equally. And it still very much can and will but now there is a big old question mark.

Garmin’s official line, from Co-COO Brad Trenkle, frames this as expanding “authentic coaching experiences” and connecting athletes to real coaches. Peaksware CEO Andy Stephens described more than a decade of partnership between the companies working toward “science-based training.”

It is all very standard acquisition language and of course tells you almost nothing about what changes for the athlete. Not so much in the short term but long term.

But reached out to TrainingPeaks and they said, “We want to proactively assure you that TrainingPeaks will continue to operate as a cross-platform ecosystem, enabling athletes and coaches to use the devices, platforms and services that best suit their needs. As noted in our press release, our objective is to expand access to more authentic coaching experiences – connecting athletes with human coaches who guide, motivate and inspire them to reach their goals.”

What We Know For Sure

• Nothing changes today. Device compatibility with Wahoo, Polar, Coros, and Suunto remains intact as of this announcement.
• This wasn’t a full-company sale. Peaksware’s music education businesses, MakeMusic, Alfred Music, and Fons are still theirs. Garmin only wanted the endurance and strength assets.
• Garmin has a pattern here. It bought Firstbeat after nearly a decade of licensing its physiology algorithms (the ones behind VO2 max estimates). It bought Tacx after years of trainer partnerships. TrainingPeaks was already deeply integrated with Garmin Connect. Buying the partner you’ve already built your relationship around is very on-brand for them.
• The coaching world noticed immediately. Looking on Reddit and across social media, this is a big surprise for a lot of people. One longtime TrainingPeaks coach put it bluntly online, admitting the news left them rattled given how past platform acquisitions have gone sideways for user data.

What We Don’t Know (And Neither Does Anyone Else)

Will TrainingPeaks stay neutral, or does “deeper integration” eventually mean the best features live behind a Garmin device or a Connect+ subscription

Other early chatter we’re seeing is connecting dots between this deal and references to coaching plans buried in recent Garmin Connect app updates — nothing confirmed, but it’s not a crazy question to ask.

There’s also the data angle worth sitting with. But one we will actually push back on because nobody really seems to care about their data and whose hands it falls into. But we should still mention it.

TrainingPeaks has quietly accumulated 25 years of something Garmin Connect alone doesn’t have: records of what a real coach actually prescribed, whether the athlete did it, and what happened next. That’s a different (and arguably more valuable) dataset than raw activity logs if the end goal is smarter, adaptive coaching tools. We’re not saying that’s the plan for Garmin but it very well could be

This Isn’t Happening In A Vacuum

This is the second major training-platform consolidation in recent memory with Strava acquiring the AI training platform Runna not long before this. It’s becoming an arms race like so many other platforms. And the pattern is clear: the companies that own your watch and your social feed want to own your training plan too, rounding out a 360 degree ecosystem of keeping you locked in. Apple wrote the book on this, and now the biggest companies in endurance are executing on it too.

Whether that’s good or bad for athletes probably depends entirely on execution, and neither Garmin nor Strava has fully shown its hand yet.

Our Thoughts

I actually hate being all doomsday and we’re not going to pretend we have a hot take on where this lands. Nobody does yet, including, probably, the product teams at Garmin who just started figuring out the integration roadmap and the folks at TrainingPeaks who will soon work for Garmin.

What we do know is, if you’re a coach with athletes scattered across five watch brands, or an athlete who chose your device specifically because TrainingPeaks made it irrelevant, nothing changes right now. But this is worth watching closely over the next few months and we’ll keep digging and update as TrainingPeaks or Garmin says more.
