Inside 140.6
What 140.6 adds to your daily routine
Choose 140.6 when you want the plan, activity log, fuel, and recovery together on iPhone.
1. TrainingPeaks — coach and device-connected plans
TrainingPeaks publishes a triathlon plan marketplace and supports structured workouts on compatible devices. It is a sensible starting point if you already have a coach using the platform or a hardware workflow you need to preserve.
Check what your plan purchase includes, what requires a platform subscription, and which actions work on your phone. A plan, access to analytics, and personal coaching are different purchases and should be compared separately.
2. MOTTIV — endurance plans and community
MOTTIV combines plans for amateur endurance athletes with workout explanations and a community. Its published integrations cover several common training services, including Garmin, Strava, Wahoo, Zwift, and TrainingPeaks.
It belongs on your shortlist if you value that community and already use those services. Verify the features included in the current access tier and try a sample week against your own schedule.
3. 140.6 — a connected daily iPhone diary
140.6 connects a multisport plan with activity history, fuel logging, and recovery check-ins. You can edit individual sessions and review proposed coach changes before applying them. The screenshot shows its weekly Plan view using synthetic demonstration data.
We make this app. We recommend evaluating it for this daily iPhone workflow, not as the winner of a comparative performance test. It does not stand in for every specialist device integration, coaching service, or workout-export format. Confirm your requirements before paying.
4. TriDot — dedicated triathlon planning
TriDot centers its product on triathlon planning and offers coaching options. Compare the sample sessions, the available coaching relationship, and how it handles your actual weekly availability.
Provider descriptions of an AI planning system explain what it offers; they are not independent proof that it will deliver a better race result for you. Evaluate the usable plan and support you receive.
5. TrainerRoad — a cycling-centered training workflow
TrainerRoad publishes triathlon plans within a platform centered on cycling training. It is worth comparing if structured cycling is already central to your preparation.
Inspect the swim and run portions as carefully as the bike workouts. Confirm your trainer, phone, and any outdoor workout delivery requirements against the current product documentation.
How we compare these apps
The five positions organize different workflows; they are not measured rankings or star ratings. We selected relevant triathlon options and compared public product information. We have not conducted a controlled training-outcome test across them.
Use the same trial task in each candidate: find tomorrow’s workout, explain its purpose, change a session, and check the result. Then test any essential device connection and read the access terms.
Common mistakes when choosing a training app
Do not assume an app’s ability to read completed workouts means it can send structured sessions to your watch. Do not compare a plan-only price with a package including a human coach. Choose the workflow you can actually use consistently.

Frequently asked questions
Which is the best triathlon training app?
It depends on your workflow. Compare TrainingPeaks for coach and device-connected plans, MOTTIV for community, 140.6 for its daily iPhone diary, TriDot for triathlon planning, and TrainerRoad for cycling-centered training.
Is this an independent ranking?
No. We publish 140.6 and disclose that interest. The list compares public product information by use case; it does not report comparative test scores or race outcomes.
Should I switch if my coach already uses another platform?
Discuss the workflow with your coach first. The right tool needs to support the relationship and device connections you depend on.
Build your week around your race and the time you actually have.
