TrainingPeaks alternative

Leaving TrainingPeaks? Here is what you would land on.

Everything a coaching platform is expected to do — calendar, structured builder, load and form, peaks, laps, an annual plan — with lactate testing as the thing the zones are actually built from, at €14.99 a month for unlimited athletes.

Why people are asking this in 2026

Garmin acquired TrainingPeaks and TrainHeroic in July 2026. An acquisition is not a verdict — TrainingPeaks is a mature product with a deep bench and it is not going anywhere this year. But it is a fair moment to ask who owns the platform your coaching business runs on, and where its roadmap points once a hardware company owns it.

Coaches have seen the other ending too. Specialized bought Today’s Plan in 2019 and shut it down in March 2024. Wahoo closed RGT in October 2023. If you are re-reading that list and thinking about where your athletes’ history lives, that instinct is worth acting on while it is cheap to act on.

LaChart is independent and funded by the people who use it. That is a smaller claim than it sounds — it means no investor timeline is deciding what happens to your data. It also means we are a great deal smaller than TrainingPeaks, which is the honest half of the same sentence.

The difference

Where LaChart is not the same product

Lactate is the product, not a module

LT1 and LT2 by six methods — log-log, IAT, OBLA 2.0–3.5, LTP1/LTP2, Dmax and baseline — with the measured points drawn on the curve. Run as many tests as you like; nothing here is metered or sold by the test.

Zones from a measurement, not a percentage

Every zone, every TSS figure and every time-in-zone chart downstream is anchored to two thresholds you actually measured, rather than a fraction of an estimate of a fraction.

Tag any interval with a blood sample

Not only formal step tests. Drop a lactate reading onto any lap of any workout and it is read against that athlete’s own curve.

One price, unlimited athletes

€14.99 a month for a coach, €6.99 for an athlete on their own. It does not step up as your roster grows.

Smart trainer control built in

Pair over Bluetooth and execute a structured session with automatic resistance (FTMS) — no third subscription in the middle.

The calculators are free and need no account

Lactate curve, training zones, FTP, TSS, VO₂max, race prediction. Send an athlete a link without asking them to sign up for anything.

The honest half

Where TrainingPeaks is the better choice

If any of these is central to how you work, stay where you are — you would be trading down, and finding that out a month in helps neither of us.

The ecosystem is not close

TrainingPeaks has spent two decades accumulating third-party integrations, and a lot of tooling in this sport speaks its format first. If your workflow depends on something niche plugging straight in, check it before you move.

There is no training plan marketplace

TrainingPeaks sells a large catalogue of pre-built plans and gives coaches a storefront to sell their own. LaChart has no equivalent.

No WKO-class modelling companion

WKO5 does power-duration modelling well beyond what LaChart attempts. If that is the centre of your practice, it is a real gap.

We are young and small

Fewer coaches, a shorter track record and a smaller team. That cuts both ways — you can email the person who wrote the feature — but it is the trade you are making.

What each one costs

Checked September 2026. TrainingPeaks prices change and vary by plan and billing period — check their site rather than taking ours for it.

Plan	Price	What it includes
LaChart — coach	€14.99 / month	Unlimited athletes. Lactate testing included and unmetered. Two weeks free.
LaChart — athlete	€6.99 / month	For an athlete training themselves, without a coach.

Moving across

What switching actually involves

There is no one-click importer that reads a TrainingPeaks account. Your history comes across through Strava or Garmin Connect — which is where nearly all of it was recorded to begin with — and it arrives with the full streams rather than daily summaries.

STEP 1

Connect Strava or Garmin

One OAuth click each. Your history backfills on its own — rides, runs and swims with power, heart rate, pace, cadence, laps and per-second streams, not just summaries.

STEP 2

Set zones from a real test

Enter an existing lactate test or run a new one. LT1 and LT2 come out by six methods with the measured points on top, and every zone downstream is anchored to them.

STEP 3

Build the week

Structured sessions with targets in watts, pace, heart rate or the athlete’s own zones, dropped onto their calendar.

STEP 4

It reaches the watch

The session is written into their Garmin Connect calendar with every step and target intact. You can still export TCX or FIT if something downstream needs it.

Questions

The ones people actually ask

Can I import my TrainingPeaks history into LaChart?

Not directly from a TrainingPeaks account. You connect Strava or Garmin Connect and LaChart backfills your history from there, including power, heart rate, pace, cadence, laps and per-second streams. For nearly every athlete that is the same history, because that is where the device uploaded it first.

Does LaChart calculate CTL, ATL and TSB the same way?

It uses the same exponentially-weighted model the sport standardised on, so fitness, fatigue and form read the way you expect. Load can be computed from power, pace or heart rate depending on the sport and what the session recorded.

Can I send structured workouts to a Garmin watch?

Yes. A session you build is written into the athlete’s Garmin Connect calendar as a structured workout — the steps become laps on the device, with targets intact. TCX and FIT export are also available for anything else downstream.

Is lactate testing an extra cost?

No. Lactate testing is included in the plan and is not metered — there is no per-test charge and no test credits to buy.

What does LaChart cost?

€14.99 a month for a coach with unlimited athletes, or €6.99 a month for an athlete training alone. There is a two-week free trial, and the calculators are free without an account.
