Stopa vs TrainingPeaks
TrainingPeaks is a full coaching platform with analytics Stopa does not attempt, at $134.99 a year. Stopa imports the plan you already have and syncs it, for $49.99. A side-by-side of where each one earns its price.
TrainingPeaks is twenty years of endurance software: a workout builder, a plan marketplace, a coach-athlete workspace, and the analytics most of the sport quotes by name. Stopa does one slice of that and nothing else.
So this is not a like-for-like fight, and pretending otherwise would waste your time. The honest question is narrower: for a self-coached athlete who already has a plan and mainly needs it on the wrist, is the platform worth $134.99 a year?
Side by side
TrainingPeaks' figures were taken from their own site on 16 August 2026. If something here has gone out of date, it is an error rather than a tactic — tell us and it gets fixed.
| STOPA | TRAININGPEAKS | |
|---|---|---|
| Where the plan comes from | Yours — Excel, PDF, plain text, or ChatGPT/Claude output | Built in their workout builder, bought from their plan library, or written by your coach |
| Import a coach's plan (Excel, PDF, chat transcript) | Yes — that is the product | No — nothing accepts a plan file from outside |
| Apple Watch structured workouts | Yes, pushed to the native Workout app | Yes |
| Other watches | Garmin, Suunto, COROS, Wahoo and Zwift — through a connected intervals.icu account | Garmin, Wahoo, Zwift, Suunto, Polar — natively |
| Training analytics (TSS, CTL/ATL, PMC) | No | Yes — the reason most people are there |
| Coach ↔ athlete workspace | No, single athlete | Yes, and it is the core of the business |
| Web app | No, iPhone only | Yes |
| Price (self-coached) | $5.99/mo or $49.99/yr | $19.95/mo or $134.99/yr |
| Coached plans | — | $149 / $229 / $359 per month |
| Free trial | 7 days on the yearly plan | 14 days |
| Free tier | No — you see week 1 of your plan before you pay, and your plan stays saved if you stop | Yes, a free Basic account — but in their own words "future workout planning is restricted" on it |
| Reads a plan written in your language | Yes — the plan reader itself speaks 7: EN, CS, ES, DE, FR, IT, PT-BR, so a Czech coach's spreadsheet is read in Czech | — no plan import, so nothing to read (see the row above) |
| Android | Planned, not shipped — iPhone only today | Yes |
The differences, in full
Import versus build
TrainingPeaks assumes the plan is created inside it — you build each workout in the builder, buy one from the library, or your coach writes it into your calendar. That is a coherent design, and if your coach is already on TrainingPeaks it is the right answer.
It has no path for the plan that arrives as a file. The Excel your coach emails you, the PDF from a book, the sixteen weeks you generated with an LLM — all of those are retyped by hand, one workout at a time. Stopa exists because that retyping is the single most common thing self-coached athletes complain about, and it reads all of those formats directly.
One is a platform, one is a pipe
TrainingPeaks wants to be where your training lives: history, fitness curves, peak performances, the conversation with your coach. Stopa does not want that job. It reads your plan, gets it onto whatever watch you own, matches what you actually ran back against what was planned, and stays out of the way.
If you want a Performance Management Chart, Stopa has nothing for you and this page is not going to invent something. If you want your plan on the wrist and nothing else, you are paying $85 a year extra for charts you do not open.
A third of the price
$49.99 against $134.99 a year, and you see your own plan in your paces before you pay a cent.
What TrainingPeaks does better
Genuinely, not as a formality.
The analytics. TSS, CTL, ATL, the Performance Management Chart, peak-power and peak-pace tracking across years of history. This is a real discipline built over two decades and Stopa attempts none of it.
Working with a coach. If a human coach writes your training, TrainingPeaks is the workspace the sport standardised on. They see your files, comment on individual sessions, adjust next week. Stopa has no coach-facing side at all.
Polar, and no middleman on Garmin. TrainingPeaks connects to Garmin, Wahoo, Zwift and Polar directly. Stopa reaches Garmin, COROS, Wahoo and Zwift through intervals.icu, which is a second free account you have to hold and connect — and it does not reach Polar at all.
A web app. Planning a sixteen-week block is genuinely nicer on a large screen. Stopa is an iPhone app; there is no web version and none planned.
A plan library. Hundreds of structured plans to buy if you do not have one. Stopa does not sell plans.
A free tier. A free Basic account can still get workouts onto a watch, even though it restricts planning ahead. Stopa has no free tier: you see week 1 of your own plan before you pay, the yearly plan starts with seven days free, and after that it is a subscription.
Which to pick
Choose TrainingPeaks if
You work with a coach, you read your own fitness charts and would miss them, you want everything on one platform across years, or you want to buy a plan rather than bring one.
Choose Stopa if
You are self-coached, your plan already exists as a file or a chat transcript, and what you actually need is for it to appear on your watch every morning without you retyping it — for a third of the price.
They also coexist without much friction: some athletes keep TrainingPeaks for the history and use Stopa to get a coach's spreadsheet onto the watch without the retyping.
