Completing a triathlon — typically a swim/bike/run event — is quite an accomplishment, and training for one can take months of work. But working toward peak performance could be a little more efficient with the right technology on your side.

Whether you’re looking for a virtual coach, customized workouts, or the peer support and motivation that group training provides, there’s an app for that.

In choosing the best triathlon apps for iOS and Android devices, we looked for amazing content, reliability, and stellar user reviews. Here’s what we considered while making our selections:

  • Price: Most of these apps have free features that you can access with a simple download, and some offer additional features with in-app subscriptions.
  • Ratings: We selected apps with ratings of 4 out of 5 stars or higher from both iOS and Android users (there’s one exception on this list).
  • Reviews: We read hundreds of reviews to find out what triathletes loved (or didn’t love) about each of these apps.
  • Versatility: We focused on apps that are compatible with a wide variety of smartwatches and heart rate monitors because everyone’s training tools look a little different!

All the apps on our list have also been vetted to ensure they meet Healthline’s business standards and align with our approach to well-being. Read more about our vetting process.

Whether you’re already in a triathlon club or you’re looking to join a community of athletes, Strava can help make your training a little more social.

Think of it as Facebook for your workouts. Strava turns your smartphone into a sophisticated tracker and allows you to monitor and analyze your personal stats, as well as how you stack up to others on popular stretches of road and trail through a segment leaderboard.

To keep your training fresh and easily find a new route, Strava has the world’s largest road and trail network available. You can also use Bluetooth to connect your smartwatch or heart rate monitor and push data from a pool or open water swim to the app.

Strava is compatible with Apple Health, Garmin, Fitbit, Polar, and more.

You can also upgrade to a premium account (for a monthly or annual cost), which provides detailed heart rate data, a training log feature, and personalized challenges. But even without the subscription, Strava is one of the best free fitness apps out there.


  • The app tracks swimming, biking, and running.
  • It’s compatible with most trackers and heart rate monitors.
  • You can choose whether to share your data with friends.
  • It’s great for clubs and community building.

Best for personal coaching


  • Price: free or $$
  • iOS rating: 4.9 stars
  • Android rating: 4.7 stars

While you can log plenty of other activities through the app, V.O2 (also referred to as “VDOT”) was designed with run coaching in mind. If you have a personal triathlon trainer, they can program your workouts in the app, leave comments, and track your progress (talk about accountability!).

If you use a Garmin or COROS smartwatch, your coach’s run workouts will appear each day as they’re scheduled. Your watch will track you as you complete the workout and send your data directly to VDOT for your coach to review.

If you don’t have a Garmin or COROS, you can still use VDOT by recording your workouts through Strava. And if you don’t have a coach, VDOT can help you find one! They also offer a few subscription options for virtual coaching, including their V.O2 Adaptive Trainer option, which uses AI to customize a plan based on your goals.

While your coach can schedule days where you’re focused on biking or swimming, VDOT doesn’t allow them to program swim or bike workouts directly into your Garmin — you’ll have to retroactively fill out your swim or bike workout manually in the app.


  • The app allows you to easily communicate with your coach.
  • It lets your coach create daily workouts that sync directly to a Garmin or COROS smartwatch.
  • It’s compatible with Strava.


  • The app requires a coach or paid virtual training program to be useful.
  • Coaches can program only guided run workouts (not swims or bikes).

Does the Apple Watch have triathlon tracking?

Historically, the Apple Watch has been able to track swimming, biking, and running individually. But now, on Apple Watches running watch OS9, you can select “Multisport Triathlon” as an activity. This will track you from swim to bike to run (as well as your transition times) without needing to touch your watch.

Just note that the Apple Watch’s battery life can be an obstacle, so make sure that you’re fully charged!

How do you keep track of triathlon training?

Triathlon training isn’t a one-size-fits-all approach, so you’ll have to find a method that works best for you. Some people track their training the old fashioned way (spreadsheets, anyone?), but there are plenty of apps that will help keep track of your data and workouts right from your phone.

The right program for you will depend on your experience, fitness level, and goals.

Finding a coach or a triathlon club is an easy way to get started, especially if it’s your first race.

Do triathletes use Peloton?

Peloton’s cycling, running, and strength classes can be a nice addition to your training regimen. However, triathlon is an endurance sport, so it’s best to stick to a program catered specifically to your progression in the swim, bike, and run disciplines.

If you’re simply trying to log time in the saddle at home, the Peloton bike’s “Just Ride” or “Scenic Ride” features are likely your best bet for training.

Triathlon training looks different for everyone, and the right triathlon app for you will depend on your goals and current level of fitness. But whatever your goals may be, there’s no doubt that technology is your friend when it comes to tracking data, programming workouts, and staying connected with coaches and fellow athletes. Happy racing!
