TrainingPeaks vs AdaptCycling: the analysis platform vs the coach that writes the plan

Ask a hundred endurance coaches what they run their athletes on and most will give you the same answer: TrainingPeaks. It has been the industry standard for two decades, it’s trusted by more than thirty national federations, and its Performance Management Chart — the Fitness, Fatigue, and Form curves built from TSS — is so widely used that it has quietly become the shared language of the sport. When people praise TrainingPeaks, they praise its depth: a workout builder that handles the most baroque interval sets, the deepest device integrations in the business, and analytics that go practically bottomless once you add WKO5. None of that is marketing puff. For a coach and athlete working together, it is genuinely the best tool in the world.

Spend an afternoon in the cycling forums, though, and the same handful of complaints surface again and again. It’s expensive — $19.95 a month — and the real analytical firepower lives in WKO5, a separate $169 purchase that Premium doesn’t include. The free tier is widely described as hobbled: you can log today’s ride, but you can’t schedule tomorrow’s. The interface draws words like “clunky,” “overwhelming,” and “stuck in 2010,” especially on mobile.

Read between those reviews and they all circle the same thing. TrainingPeaks is a magnificent rear-view mirror — it tells you, in exquisite detail, what you did. What it doesn’t do is tell you what to do next. There is no plan unless you write one, buy one, or pay a coach to. The numbers are immaculate; the decision is still entirely yours. For riders who have a coach, that’s exactly right. For the self-coached, it’s the whole problem.

On July 22, 2026, Garmin announced it had acquired TrainingPeaks and TrainHeroic from Peaksware. TrainingPeaks continues as a separate business unit, about 120 staff moved to Garmin, and nothing user-facing changed at the announcement: pricing, accounts, coach relationships, and syncing from non-Garmin devices all work exactly as they did before. If you log into TrainingPeaks today, it’s the same product you had in June.

The open question is what happens to the ecosystem around it. TrainingPeaks has always been vendor-neutral — a Wahoo, a Polar, a Hammerhead pushes rides in and pulls structured workouts out on equal footing with a Garmin. Whether that neutrality survives inside a device company is unanswered: when DC Rainmaker put the third-party-access question to Garmin directly, no commitment came back. The precedent people keep citing is Garmin’s 2020 purchase of Firstbeat, the analytics engine it once licensed to competing watchmakers — after the acquisition, new Firstbeat features stayed on Garmin devices. That history is why coaches and athletes are asking the question at all.

For a self-coached rider, though, the acquisition doesn’t change the core calculus of this page. TrainingPeaks was the industry’s best analysis-and-delivery surface before July 22 and it still is — and it still doesn’t write your plan or adapt it when your week falls apart. Whoever owns it, that’s the job you’re left doing yourself, and it’s the job AdaptCycling exists to do.

This is the cleanest way to hold the two products in your head: TrainingPeaks is the surface coaching happens on; AdaptCycling is the coaching. TrainingPeaks was built around the coach–athlete relationship, and it assumes the judgment — what this week should look like, why, and how to react when it falls apart — already lives in someone’s head. Usually a coach’s. Sometimes yours, if you’ve put in the years to learn periodization.

AdaptCycling puts that judgment in the product. It reads the rides in your Wahoo, Hammerhead, Polar, Rouvy or intervals.icu account the day you connect, estimates your FTP from your real power curve instead of asking you to suffer through another ramp test, and writes a plan aimed at your goal — with a plain-language reason attached to every session. You’re not handed a blank calendar and fifteen charts and left to interpret them. You’re handed a decision, and the why behind it.

Buying a plan from the TrainingPeaks Marketplace gets you a fixed template. It was written for an average rider hitting every session on schedule — not for the week your kid gets sick, a work trip swallows three days, or a Saturday group ride turns into an accidental threshold effort. TrainingPeaks’ “Dynamic” plans only slide the calendar dates to line up with your start day; they don’t look at what you actually did and reshape what comes next. Their own advice for a missed week is to restructure it by hand.

That is the gap AdaptCycling was built to close. Miss key sessions and the solver re-solves the rest of the week around your goal, instead of pushing everything forward a day. Bank an unplanned hard ride and the days after it ease off so the load still lands where it should. An illness or a trip you can tell the coach about on the Coach tier, and it reworks the plan once you agree.
