Your first triathlon: the plan to finish your super sprint with confidence

400 m swim, 10 km bike, 2.5 km run: the super sprint is the gateway to triathlon. You don't need to be an accomplished swimmer, cyclist and runner: you need to link all three without going into the red. You give your race date and your slots in each discipline: Trainetic lays out the weeks.

Five rules for a first triathlon

They come from the advice of the French Triathlon Federation (FFTRI) and from published beginner plans. Your plan applies them.

Three sessions a week are enough to start. One per discipline, from thirty minutes to an hour: that's the base the Federation recommends for a beginner. Your plan asks for at least one of each for a super sprint.

Everything is done at a pace where you can talk. For a first triathlon, the goal is to reach the finish with a smile. Endurance does most of the work.

Prepare the swim first. It's the one discipline you can't “finish by walking”. Being comfortable over the distance in the pool, without stopping, is the best starting point.

Linking bike and run is a skill you learn. The first minutes of running off the bike surprise everyone: your legs feel like wood. One brick session a week is enough to get used to the feeling.

Nothing new on race day. Kit, shoes, laces, drink: everything you wear in the race should have been used in training.

What your plan sets for a super sprint (XS)

The Trainetic engine settings for this format. Everything else — durations, paces, volume — is calculated from your level and the slots you give it.

Benchmark	In your plan
Minimum slots	One swim session, one bike session and one run session per week
Long ride	No dedicated long ride: over 10 km, the bike leg stays short
Long run	Up to 35 minutes, from three run sessions a week
Run off the bike (brick)	Up to 20 minutes, with the bike-to-run transition rehearsed
Taper	Two weeks, volume down and intensity maintained

Your race comes the day after your last session: the day before, a short shake-out session in each discipline.

The sessions of a first triathlon

Each discipline has its own, spread across your slots without ever placing two hard sessions on the same day.

Swimming, in meters

Technique drills to swim more easily, then sets measured in meters with rest at the wall. Distances adjust to the length of your pool.

Bike and run, at easy pace

Easy rides and runs to build your base, and a few harder efforts as the date gets closer.

The brick session

Bike then run, no break, with a timed transition. It's the session that feels most like your race, and the one that builds the most confidence.

What if I can only swim breaststroke?

Breaststroke is allowed in triathlon, and many beginners swim their first super sprint that way. What matters is being comfortable in the water over the whole distance. If you can't yet swim 200 m in one go, a few sessions with a club will save you more time than a plan.

Five mistakes in a first triathlon

Starting too fast in the water. The adrenaline of the start makes you swim beyond your means. A calm first hundred meters saves time on everything that follows.

Lining up at the front at the start. On the side or at the back, you swim in calmer water and avoid knocks.

Neglecting transitions. They are part of the race. Rehearsed in training, they become simple moves; improvised, they cost minutes and energy.

Giving everything on the bike. The run comes right after. A comfortable pace on the bike leaves you legs to run.

Discovering open water on race day. A lake or the sea is nothing like a pool: no wall, no line on the bottom. One or two open water sessions before the race change everything.

Where these values come from

Every benchmark on this page comes from a public source.

The three sessions a week, one per discipline, from thirty minutes to an hour, at an intensity where you can talk, are the base recommended by the FFTRI for beginners.

The once-a-week brick session and the transition under a minute are benchmarks from TrainingPeaks and published training plans.

The two-week taper, with reduced volume and intensity maintained, follows the meta-analysis by Bosquet (2007) and the one published in PLOS One (2023).

For a first triathlon, the Federation offers a one-race license, the Licence Expérience, which you take out when registering with the organizer.

Questions people ask before a first triathlon

How many weeks to prepare for a first triathlon?

For a super sprint, five to eight weeks are often enough for someone who already does a little of one of the three disciplines. Starting from scratch, allow two to three months instead. Your plan is built around your race date.

Can you prepare for a triathlon starting from zero?

Yes, as long as you can swim. If you don't run at all, start with the beginner running plan: triathlon will come next, on a solid base.

Do I need to swim front crawl?

No. Breaststroke is allowed, and many first triathlons are swum that way. Front crawl becomes useful as distances get longer.

How many sessions a week?

Three at least, one per discipline. Four to six let you progress faster and add a brick session. Your plan fills the slots you give it, and tells you if any are missing.

Do I need a license or a medical certificate?

For a single race, the FFTRI offers a Licence Expérience, taken out when you register with the organizer. The medical certificate is replaced by a health questionnaire. Check the conditions for your race.

Is a wetsuit mandatory?

It depends on the water temperature, measured on race day: FFTRI rules make it mandatory below 16 °C and ban it in warm water, above about 24.5 °C. The exact thresholds are set out in the current rules and announced by the organizer: check them before you register.

Super sprint or sprint to start?

The super sprint is made for discovering the sport. If you already practice one of the three disciplines regularly, a sprint is within your reach: see the sprint plan.

Is it free?

Yes, for the essentials: creating your triathlon plan, taking it with you as a PDF and tracking your sessions. A subscription exists for advanced features, like the written analysis of each session. The plan itself doesn't need it.
