TrainingPeaks is the industry standard for endurance coaches and serious competitive athletes who want deep periodization tools and a coach-athlete workflow. Fitiv delivers the same core training load metrics — TRIMP, TSS, acute and chronic load — in a mobile-first app built around the Apple Watch, at a fraction of the cost, without requiring a coach.

What TrainingPeaks Does Best
TrainingPeaks is 25 years into building tools for endurance coaches, and the platform depth reflects it. The Performance Management Chart — which plots your fitness (CTL), fatigue (ATL), and form (TSB) over time — is the most detailed version of that visualization available in any consumer fitness app. For athletes who want to understand long-range periodization, plan a peak for a specific race, and analyze how their training built fitness over a 12-month cycle, TrainingPeaks gives you more data surface to work with.
The coach-athlete workflow is genuinely unmatched. If you work with a coach who builds structured workouts with power targets, pace zones, and duration blocks, TrainingPeaks is the platform those workouts are delivered through. Coaches can review your completed workouts, compare planned vs. actual TSS, and adjust the training calendar in real time. This is an entire professional infrastructure that Fitiv does not replicate.
Structured workout creation in TrainingPeaks is sophisticated. You can define intervals with power or pace targets, specify warmup and cooldown protocols, and push those workouts to compatible Garmin, Wahoo, or other devices for execution. For athletes training by power or pace zones, this is a meaningful edge.
TrainingPeaks' Garmin integration is one of the deepest available. If you race with a Garmin head unit, the two-way sync between TrainingPeaks and Garmin Connect is seamless and automatic.
What Fitiv Does Best
For the self-coached athlete — which describes the majority of recreational and amateur competitive athletes — TrainingPeaks charges $19.95 to $34.95 per month for a web platform designed primarily around a coach-athlete relationship you may not have. Fitiv delivers the same foundational training load metrics at a fraction of that cost, on the device most athletes already use throughout their day.
Mobile experience is where the gap is most visible. TrainingPeaks exists primarily as a desktop web app. The mobile app is functional but clearly secondary — detailed PMC charts, calendar management, and structured workout editing are designed for a laptop screen. Fitiv is built mobile-first from the ground up, which means your training load, readiness score, and workout logging are designed for the moments that actually matter: the morning check before you head out, the wrist glance between sets, the post-workout summary on the drive home.
HRV readiness is something TrainingPeaks does not build natively. The platform partners with WHOOP for biometric readiness data, but that requires a separate WHOOP subscription on top of your TrainingPeaks subscription. Fitiv integrates HRV readiness, training load, and recovery scores into a single app on a single device.
Strength training is not a TrainingPeaks use case. The platform is built for endurance sports — running, cycling, triathlon, swimming. If you also lift weights, TrainingPeaks has no structured way to log or analyze those sessions. Fitiv tracks strength workouts with sets and reps, and factors lifting stress into your overall training load calculation.
Apple Watch support in Fitiv is native and deep. There is no official TrainingPeaks Apple Watch app. You can view workouts on your watch via Garmin or Wahoo device sync, but the Apple Watch experience is not a TrainingPeaks strength.
Pricing Comparison
| Plan | Fitiv | TrainingPeaks | |---|---|---| | Free | Core workout tracking | Very limited — no PMC | | Basic paid | From $4.99/month | $19.95/month | | Premium | Varies | $34.95/month | | Annual discount | Yes | Yes | | Coach required | No | No, but optimized for coach use |
A self-coached athlete on TrainingPeaks Premium pays $419 per year for a platform that is architecturally designed around having a coach. That cost is worth it if you have one. If you are self-coached and just want TRIMP and TSS on your phone, Fitiv delivers those metrics with HRV readiness included for less than a third of the price.
Honest Assessment: Where TrainingPeaks Wins
If you have a coach, TrainingPeaks is almost certainly the right tool. The shared calendar, planned vs. actual analysis, and coach communication tools are built for exactly that relationship and nothing else does it better.
If you are training for a specific A-priority race with a detailed periodization plan — base, build, peak, taper — TrainingPeaks' visualization of long-range training load gives you more granular control over that arc than Fitiv currently provides.
For power users who analyze every watt of their indoor cycling data or build highly specific interval protocols for Garmin execution, TrainingPeaks' depth in those workflows is legitimate.
Who Should Choose Fitiv
- Self-coached athletes who want TRIMP/TSS training load without paying for a coaching platform
- Athletes who train on Apple Watch and want native, mobile-first training load tracking
- Hybrid athletes who mix strength training and endurance and want one tool for both
- Athletes who want HRV readiness integrated with training load (not as a separate WHOOP subscription)
- Budget-conscious athletes who want the core performance metrics without the premium price
Who Should Choose TrainingPeaks
- Athletes who work with a coach using the TrainingPeaks coach-athlete workflow
- Competitive cyclists or triathletes who want deep power analysis and structured workout execution on Garmin or Wahoo
- Athletes planning long-term periodization who want the full PMC and calendar infrastructure
- Athletes already embedded in the TrainingPeaks ecosystem with years of historical data
Frequently Asked Questions
Does Fitiv calculate TSS like TrainingPeaks? Yes. Fitiv calculates Training Stress Score based on heart rate data relative to your lactate threshold heart rate, using the same underlying methodology as TrainingPeaks. The core metric is equivalent; TrainingPeaks offers more historical visualization depth for athletes who want to analyze years of accumulated data.
What is the Performance Management Chart? The PMC is a visualization of your fitness (Chronic Training Load), fatigue (Acute Training Load), and form (Training Stress Balance) over time. Both Fitiv and TrainingPeaks calculate these values. TrainingPeaks' charting tools are more detailed; Fitiv's presentation is more accessible for daily mobile use.
Does Fitiv work with Garmin like TrainingPeaks does? Yes, Fitiv supports Garmin devices. TrainingPeaks has a longer history of deep Garmin integration and pushes structured workouts directly to Garmin head units, which Fitiv does not currently do.
Can Fitiv replace TrainingPeaks if I have a coach? Not yet. TrainingPeaks' coach-athlete workflow — shared calendar, planned vs. actual analysis, coach messaging — is purpose-built for that relationship. If your coach uses TrainingPeaks, switching your athlete account to Fitiv would break the workflow your coach depends on.
Does TrainingPeaks track HRV? Not natively. TrainingPeaks partners with WHOOP for recovery data, but this requires a separate WHOOP subscription. Fitiv includes HRV readiness in the core app without additional hardware or subscription cost.
Is Fitiv good enough for competitive athletes? Yes, for most levels of competition. Age group triathletes, competitive amateur runners, and cyclists racing Cat 4-5 regularly use training load metrics at exactly the level Fitiv provides. Elite and professional athletes who work with coaches on precise periodization will want TrainingPeaks' additional depth.
