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.

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 your last six months from Strava 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 exact gap AdaptCycling was built to close. Miss a key workout and the rest of the week is rebuilt to protect the goal, not just pushed forward a day. Bank an unplanned hard ride and tomorrow eases off so the load still lands where it should. The plan is a living thing that responds to your real training — which is what “adaptive” was always supposed to mean.
