Triathlon and Duathlon Transitions: How to Train Them to Set Your Service Apart

Learn how to teach transitions (T1 and T2) so your athletes lower their times and value your technical eye as an endurance professional.

By the ATHRIX Team ·

In the world of triathlon and duathlon, transitions are often called the "fourth discipline." Yet many coaches leave them to chance, or simply tell the athlete to "practice on race day." If you want your training plans to stand out and your athletes to see real results on the clock, mastering the technique and programming of transitions is essential.

For you, as a coach, teaching an efficient transition isn't just about speed: it's a retention tool. An athlete who shaves a minute off their personal best thanks to your technical advice is a client who trusts your professional judgment without question.

Why transitions define your quality as a coach

Any coach can pull an interval workout off the internet. But few know how to explain how to go from the water to the bike, or from the bike to the run, while minimizing energy expenditure and mental stress. By building transition training into your service, you give it a comprehensive approach that justifies the value of your coaching.

Remember that in duathlon and triathlon, total time includes time spent in the transition area. If your athlete runs fast but loses two minutes fighting with their wetsuit or shoelaces, your months of work on the track disappear in seconds.

T1: From the water (or the first run) to the bike

T1 is the most chaotic transition. In triathlon, the athlete comes out of the water with their heart rate high and, often, slightly disoriented. In duathlon, they're coming off a very intense first running segment.

Key points to teach your athletes:

  • Exiting the water: Teach them to peel off the top of the wetsuit while running toward the transition zone. That's time in the bank.
  • Setup in transition: Gear should be laid out minimally. Helmet open on the handlebars, sunglasses inside the helmet, and shoes already clipped into the pedals (if the athlete has the skills for a flying mount).
  • The mount: Practice the jump onto the bike after the mount line with them. It saves critical seconds and avoids the pileup of athletes stopping to put their shoes on.

T2: The "brick legs" challenge

The transition from the bike to the run is, perhaps, the one that most affects physiological performance. The shift in motor pattern from pedaling to striding creates that heavy feeling that can ruin the final segment if it's not managed well.

How to help your clients in T2:

  • Cadence at the end of the bike leg: Recommend that, in the last 2 or 3 kilometers of the bike, they raise their cadence and shift to a slightly easier gear to "wake up" their legs before running.
  • Fluid dismount: The technique of pulling the feet out of the shoes while still pedaling and getting off the bike while it's still moving (flying dismount) is a skill you can charge for as a differentiator in your in-person sessions.
  • Elastic laces: Make sure all your athletes use elastic laces on their running shoes. There's no reason to lose 20 seconds tying shoelaces during a race.

How to program transition training

Telling them what to do isn't enough; you have to build it into the plan. This is where your ability to structure specific sessions comes in:

  1. Dry-run transitions: Ideal for beginners. In a park, have them practice mounting and dismounting the bike 10 or 15 times in a row until the movement becomes automatic.
  2. Brick sessions: These are the classic combined workouts (Bike + Run). To be effective, the transition must be immediate, simulating race pace.
  3. T1 rehearsals: If you have access to a pool or open water, program sets where they get out of the water, run 50 meters, take off their cap/goggles, and go through the technique of removing the wetsuit.

To manage this training professionally, you can use platforms like ATHRIX. It lets you upload technical videos explaining each movement, so your athletes can watch the correct technique on their phones before heading out to train. You can also track how their transition times evolve in each test or race.

Conclusion

Transitions are the perfect opportunity to show that your coaching goes beyond watts and pace per kilometer. By focusing on these technical details, you reduce your athletes' anxiety on race day and give them a real competitive edge.

Start adding dedicated transition-technique blocks to your weekly plans. Your athletes will thank you when they see themselves move up in the overall standings simply by being more organized and efficient in the transition zone.
