Is TrainingPeaks Premium worth the money?

If you work with a coach who uses it, yes, and there is nothing to decide. If you are self-coached and mainly want CTL, ATL and TSB charts, Intervals.icu does that better for free, and the honest answer is no.

What does TrainingPeaks Premium actually add?

The Performance Management Chart, unlimited planning ahead, peak-performance tracking and comparison views. The free tier is deliberately limited to make Premium necessary. Most of what Premium adds is available free elsewhere, minus the coach workflow.

Is there a free alternative that is as good?

Intervals.icu, for analysis specifically, and it is better rather than merely equal — adjustable time constants, custom load metrics, integrated HRV and wellness tracking, and documented formulas. What it has no version of is coach-athlete workflow or a plan marketplace.

Does TrainingPeaks work for hybrid athletes?

Only for the endurance half. TSS is defined as intensity relative to an endurance threshold, and a set of squats has no threshold and no normalised power. Your lifting either does not appear or appears as a number you invented, which then pollutes every chart downstream.

Should I pay for TrainingPeaks or hire a coach?

If the budget only covers one, the coach, by a wide margin. A coach with a spreadsheet beats a Performance Management Chart with nobody reading it. TrainingPeaks is most valuable as the medium for a coaching relationship rather than as a substitute for one.

Is TrainingPeaks Worth It? One Question Decides

If yes, TrainingPeaks is worth it and the rest of this page is background — your coach works there, your compliance is reviewed there, and the friction of fighting that exceeds any saving.

If no, a free tool models your load better and the honest answer is no.

What you are actually paying for

Not the Performance Management Chart. That is the thing people think they are buying, and it is the thing available free elsewhere.

You are paying for the coach relationship as software. A coach writes structured sessions, they appear on your calendar, you execute, the file returns, and compliance and load sit side by side for both of you. Nothing else in the category does this properly, and if that is your situation the value is obvious.

Secondarily you are paying for the plan marketplace — buy a real coach's twelve-week plan and have it populate your calendar — and for institutional acceptance, because coaches, teams and federations use it.

Why the free option models load better

This surprises people. Intervals.icu is maintained by one developer, costs nothing, and does more with your load data than TrainingPeaks does.

You can set the time constants. CTL and ATL are exponentially weighted averages with conventional 42 and 7 day constants, chosen for road cycling decades ago. Intervals.icu lets you change them; TrainingPeaks presents the output as finished.

Custom load metrics. Which matters the moment your sport is not the one TSS was designed around.

Integrated HRV and wellness, free. TrainingPeaks charges for a thinner version.

Documented formulas. You can find out how a number was made. Why that matters over years of training.

The full comparison is worth reading if this is your decision: TrainingPeaks against Intervals.icu.

The verdict table

Your situation	Worth it?
Coached, coach uses TrainingPeaks	Yes, decided
Self-coached, want load charts	No — Intervals.icu, free and better
Want to buy a structured plan	Yes, the marketplace is real value
Endurance athlete, want the polish	Marginal
Also lift seriously	No — half your load cannot enter it
Budget covers either this or a coach	The coach, clearly
Want a mobile-first experience	Yes, Intervals.icu is web-first

The limit that applies regardless

TSS cannot represent resistance training, and this is definitional rather than a gap someone forgot to fill.

TSS is intensity relative to an endurance threshold — FTP for cycling, threshold pace for running — integrated over time. A set of eight squats at RIR 2 has no threshold, no normalised power and no intensity factor.

TrainingPeaks handles this by letting you type a TSS figure for a strength session. That number is invented, it flows into your CTL, and every decision you make from that chart afterwards is partly fictional. The full argument, with what to use instead.

The failures land on the weeks that matter most:

A heavy lower-body week plus a threshold run reads as easy in TSB terms.
A bike deload while lifting volume climbs reads as recovery.
The ramp rate — the load measure with the best injury evidence — is computed on part of the load. Compute it on all of it.

And the corollary on the strength side: TrainingPeaks will never tell you your weekly hard sets per muscle group, which is the strength equivalent of CTL and the number that actually governs whether you are progressing. Count it.

What to do instead, by situation

Coached: pay for it. Stop reading.

Self-coached endurance athlete: move to Intervals.icu today. It is free, it is better at analysis, and export your data periodically because it depends on one maintainer.

Self-coached and want prescription rather than analysis: TrainingPeaks is not really built for this either. Look at Runna for running or TrainerRoad for cycling, both of which write and adapt the plan. Where TrainerRoad lands.

Lifting and endurance both matter: you need three numbers TrainingPeaks structurally cannot produce — hard sets per muscle group against your endurance load, a ramp rate on total training, and a deload trigger reading both fatigue sources. What both halves on one ledger looks like.
