Triathlon is three sports plus the logistics of juggling them, so your app has to handle swim, bike, and run in one place — and ideally adapt as life gets in the way. TrainingPeaks is the planning industry standard, TriDot is the most advanced AI coaching, and Strava is the accessible free start. Here’s how the best triathlon apps compare in 2026, with real pricing.
TrainingPeaks: the planning standard
TrainingPeaks is the proven platform for planning, tracking, and analyzing workouts across all three disciplines plus cross-training — and the standard for working with a coach. The free tier allows limited uploads; Premium is $19.95/month or $119.95/year. If you follow a structured plan or work with a coach, this is the hub.
TriDot: the most advanced AI coaching
TriDot builds optimized, personalized plans by analyzing your data (age, environment, even genetics) and adapting automatically. It’s the most sophisticated triathlon-specific AI, with tiers from $29/month (Essentials) up to $199/month (Premium, includes a human coach). Worth it for athletes who want adaptive coaching without hiring a coach outright.
Strava: the accessible free hub
Strava is the easiest multi-sport app to start with — a free model anyone can track with immediately across swim, bike, and run. Premium ($11.99/month) adds route planning, training plans, segment analysis, and AI feedback. For social motivation plus basic structure, it’s the low-friction choice.
MySwimPro & Garmin Connect: fill the gaps
For the swim leg specifically, MySwimPro ($19/month or $99/year) provides structured pool sessions and drill coaching that general apps lack. And if you train with a Garmin watch, Garmin Connect is free with the device (Connect+ is $6.99/month) and now offers genuinely useful daily workout suggestions based on training load and recovery.
Side-by-side comparison
| App | Price | Best for |
|---|---|---|
| TrainingPeaks | Free; Premium $19.95/mo or $119.95/yr | Planning + coach collaboration |
| TriDot | $29–$199/mo | AI adaptive triathlon coaching |
| Strava | Free; Premium $11.99/mo | Accessible multi-sport + social |
| MySwimPro | $19/mo or $99/yr | Structured swim coaching |
| Garmin Connect | Free w/ device; Connect+ $6.99/mo | Garmin owners |
Building your triathlon stack
A common setup: Strava (free) for logging all three sports, plus one coaching brain — TrainingPeaks if you have a coach or plan, or TriDot if you want AI to adapt everything. Add MySwimPro if your swim is the weak leg. Garmin owners get much of this free via Connect.
What to expect realistically
The hard part of triathlon isn’t the app — it’s consistency across three disciplines around real life. Pick a platform that adapts when you miss a session (TriDot, TrainingPeaks plans) rather than one that leaves you behind a rigid schedule.
