IntervalCoach vs TrainingPeaks: Honest Comparison
One is a planning platform built around you and your coach. The other is an AI that decides today's session for you. Here's which fits.
Quick verdict
Pick TrainingPeaks if you work with a human coach, or you want the deepest manual planning platform and don't mind doing the planning yourself. If you'd rather a coach that actually decides and adapts today's session for you, automatically and on your Intervals.icu data, IntervalCoach does that at a fraction of the price.

When to pick TrainingPeaks
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. If you work with a human coach, or you’re an experienced self-coached athlete who wants to build and analyse your own plan in fine detail, TrainingPeaks is hard to beat.
It’s also the right home if your value is in the relationship with a coach. TrainingPeaks is where most coaches operate, so if you want a real person writing and adjusting your plan, the platform is built around exactly that workflow.
When to pick IntervalCoach
Pick IntervalCoach if you don’t have a coach and don’t want to be one. 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. If you want a planning platform and a coach, TrainingPeaks. If you want the coach to be automatic, IntervalCoach.
iOS depth, not just iOS presence
Both ship mobile apps, but they play different roles: TrainingPeaks shows you your plan, while IntervalCoach decides and adapts it. On Apple platforms IntervalCoach goes deep. Apple Health is a first-class recovery data source, HRV, sleep, resting heart rate, VO₂ max, heart rate recovery, wrist temperature, blood oxygen, body composition and menstrual cycle data flow automatically into your daily readiness signal, no third-party scripts required. App Intents and Siri shortcuts let you ask "Check my readiness" or "What’s my workout today?". Home and lock screen widgets, Apple Watch complications for training score and today’s workout, and iPad support keep the next session one glance away. Push notifications cover the daily briefing and post-workout analysis, and the entire app is natively localised in all 13 languages, including Chinese, Polish and Czech. If you live in the Apple ecosystem and want your training app to use what Apple already knows about you, IntervalCoach is the more native experience.
