TrainingPeaks Alternative: Free & Cheaper Apps Compared

TrainingPeaks is the category leader for training planning and athlete-coach communication – and priced accordingly. Premium currently runs around $20/month or roughly $135/year (pricing changes, check the provider for the current figure). If all you need is the analysis side – was the session good, how fit am I – you're paying for a lot you'll never open: the plan editor, coach-sharing, the marketplace.

Intervals.icu — the powerful, free web alternative

Built by a single developer and donation-supported, Intervals.icu covers nearly every metric TrainingPeaks does: power-duration curve, time in zone, a performance management chart, plus a companion iOS app that's now available. The catch: it's still a cloud service – you create an account, your data lives on someone else's servers, and syncing runs through Garmin/Strava connections. For anyone who wants full control over custom dashboards and doesn't mind the cloud, it's hard to beat.

Golden Cheetah — open-source for the desktop

Maintained by volunteers since 2006, Golden Cheetah is completely free and installed locally (Mac, Windows, Linux) – no cloud required. The modeling depth (CP curves, custom metrics) is genuinely impressive, but it's built for users willing to learn a desktop application. It's not built for a quick check after a ride – there's no iPhone app.

The third option: a lean, private app

If you don't need plan management or a full desktop suite, and just want to know on your phone right after a session whether it was good and where your form stands, that's a different category of tool. That's exactly what Endurance Debrief is built for: NP, IF, TSS, zones and the CTL/ATL/TSB curve natively on the iPhone, no account, no file ever touching a server. To be upfront: training plans, coach integration or a calendar editor are deliberately not on board – if you need those, TrainingPeaks or a real coaching tool is the better fit.

Side by side

Which one fits you

If you have a coach or need structured training plans with a sharing workflow, TrainingPeaks (or Coachbox, TrueCoach) remains the right call. If you want full control over custom dashboards and a cloud account doesn't bother you, Intervals.icu is hard to beat. If you plan your own training but want honest numbers on your last session and your form – no subscription, no server ever seeing your heart-rate and GPS data – a private on-device app like Endurance Debrief is the leanest alternative.
