IntervalCoach vs TrainingPeaks: Honest Comparison

TrainingPeaks is the platform the endurance world grew up on. Coaches deliver structured workouts through it, the Performance Management Chart (CTL, ATL, TSB) it popularised is now a universal language for fitness and fatigue, and the planning and analytics run deep. Its real moat is the network: most coaches already run their practice there, and the coach-side business tooling around client management is mature. If your coach delivers through TrainingPeaks, that alone is the strongest reason to be there too. One thing to factor in: in July 2026 Garmin acquired TrainingPeaks (and TrainHeroic), so the platform that built its reputation on working with any device is now owned by a device manufacturer. Nothing breaks for non-Garmin athletes today, but it is worth knowing where your training history lives and whether you can export it.

It’s also where most coaches are findable if you’re still looking to hire one, and the coach-facing business side (client rosters, billing, the coach marketplace) is deeper than ours. Worth knowing though: working with a human coach no longer forces the choice, because IntervalCoach has a coach mode too, see below.

Pick IntervalCoach if you don’t want to be your own coach. TrainingPeaks gives you the tools to plan; it doesn’t decide for you. IntervalCoach does, it reads 60+ recovery signals every morning and either confirms, dials back or replaces today’s session, then writes the structured workout straight to your calendar. The planning and the daily judgement call are handled for you.

We’re also natively integrated with Intervals.icu (which itself is a free, well-loved alternative to TrainingPeaks’ analytics), cover cycling, running, triathlon, swim and strength under one adaptive plan, ship in 13 languages, and price between €3 and €8 a month. The analytics go deep on their own terms too: power profile and curve, eFTP history, best efforts, progressive overload, HRV and HRV-CV, zone distribution, cohort benchmarks, and a personal recovery curve fitted to your own history. And if you do train with a human coach, there’s a coach mode: your coach switches the app to Coach view, sees every athlete they work with, compares fitness across them, opens your dashboard, calendar and plan, edits workouts and settings, and can use Coach+ on your behalf. Coach access is free; the athlete is on Max.
