Best Triathlon Training Apps for Beginners (2026, UK)

Your first triathlon puts three sports into one race, and the training has to build all three at once. That makes the app you choose more important than it is for a single-sport goal. A good beginner triathlon app lays out swim, bike and run across your week, balances the load so you progress gradually, and gets you to the start line able to complete each leg. This guide covers the apps that do the full swim-bike-run job, and it is honest about where Edge does and does not fit.

What is the best triathlon app for beginners?

For most beginners, the best triathlon app is the one that plans all three disciplines together in a single calendar and keeps the early weeks manageable. TriDot and TrainingPeaks are two of the most established names, and MyProCoach delivers structured beginner plans through TrainingPeaks. The right pick depends on how much guidance you want. Some beginners prefer a plan that adapts to their logged data, while others just want a clear week-by-week schedule to follow. All three cover swim, bike and run, which is the non-negotiable feature for a first triathlon.

What should a beginner triathlon app include?

A few things separate a genuinely useful beginner app from a generic training log:

• All three disciplines in one plan, so swim, bike and run sessions are balanced rather than piled on top of each other.
• A gradual build. Triathlon training is a big load for a beginner, so easy days and steady progression matter more than the occasional big session.
• Clear session guidance, with paces, effort or distance you can actually follow.
• Flexibility, so the plan can move when work or life gets in the way.
• Strength and mobility support, which helps protect you as running and cycling volume climbs.
• Race-distance options, from a sprint up to whatever you are aiming for.

One thing to remember: apps guide training, they do not teach you to swim. If you are new to pool or open-water swimming, book proper instruction and learn safely before you load on swim sessions.

Best apps for a full swim-bike-run plan

These apps cover all three disciplines and are built specifically for triathlon. Pricing is indicative and shown in the currency each app publishes, so check the current figure in the app before you subscribe.

TriDot builds an adaptive plan across swim, bike and run and adjusts sessions as you log them. There is no free tier, with the lowest plan around $14.99 and a 14-day free trial to try it first.

TrainingPeaks is a planning and analysis hub. The Basic tier is free, and Premium, at roughly $19.95 a month, adds drag-and-drop scheduling and deeper tracking. You can load a structured triathlon plan into it and follow every swim, bike and run session in one calendar.

MyProCoach sells ready-made triathlon plans, including beginner sprint and longer-distance options, delivered through TrainingPeaks with email access to a coach. You can buy a single plan or take an unlimited subscription.

Where does Edge fit for triathletes?

Here is the honest part. Edge is not a triathlon app. It does not build structured swim sessions, and it does not write a bike training plan for triathlon. If you want a full swim-bike-run programme, start with one of the dedicated apps above.

Where Edge earns its place is the running and strength side of a triathlete's week. Edge gives you a fully personalised plan across running, strength, HIIT and mobility, ready in 15 minutes, and a real coach you can message anytime. For a triathlete, that means your run days and your strength and mobility work can sit in a plan that flexes around your life and around the swim and bike sessions you are doing elsewhere.

Used alongside a dedicated triathlon app, Edge can cover the run and the gym so those parts are structured, progressive and supported by a coach. Used on its own, it will not prepare you for the swim or the bike, so treat it as a complement, not a full triathlon solution. More than 18,000 members use Edge for running, strength, HIIT and mobility, and the aim is simple: making fitness feel good for everyone.

How much do these apps cost?

Costs vary by app and by how much you want. Dedicated triathlon apps range from free tiers with paid upgrades to full subscriptions, and most offer a 14-day free trial so you can test the fit. TriDot starts around $14.99 with a 14-day trial and no permanent free version. TrainingPeaks has a free Basic tier and a Premium tier at roughly $19.95 a month. MyProCoach sells individual plans or an unlimited subscription through TrainingPeaks. Edge has a free 7-day trial, then costs from £19.99 a month for running, strength, HIIT and mobility with a real coach. Prices change, so confirm the current figure in each app before you commit.

A note on training safely

Training for a first triathlon is a big step up in weekly load, so build gradually, keep easy days genuinely easy, and give yourself recovery. Learn to swim safely with proper instruction before you push swim volume, especially in open water. If you feel pain, pick up an injury, or have a health condition, see a physio or GP before carrying on. Edge and the apps here support training, they do not replace medical advice.
