The sprint triathlon training plan, built on the slots you really have

750 m swim, 20 km bike, 5 km run: the sprint is short, so it's intense. You prepare for it in eight to twelve weeks, with two sessions per discipline and one brick session a week. You give your race date and your slots: Trainetic builds all three disciplines in parallel.

Five rules for sprint preparation

You find them in published plans, and your plan applies them.

Eight to twelve weeks. That's the length of most published sprint plans, from beginner to intermediate.

Two sessions per discipline. Six sessions a week is the usual benchmark for a sprint. Your plan asks for at least two of each.

A little intensity, a lot of endurance. The sprint is raced fast, but it's mostly prepared at easy pace. Faster sessions come in the middle of the plan.

One brick session a week. Ten to twenty minutes of running right off the bike, to get your legs used to the change.

Transitions count. On a short format, a minute lost in the transition area shows in the results. Rehearse them like a session.

What your plan sets for a sprint (S)

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	Two swim sessions, two bike sessions and two run sessions per week
Long ride	No dedicated long ride: 20 km remains a short effort
Long run	Up to one hour, from three run sessions a week
Run off the bike (brick)	Up to 25 minutes, at race pace at the end of the plan
Taper	Two weeks, volume down and intensity maintained

A recovery week every four weeks, and never two hard sessions on the same day, across all disciplines.

The sessions that make a sprint

Three disciplines, one week. The plan spreads them across your slots.

Threshold swimming

Sets of 100 and 200 m at your threshold pace, calculated from your 400 m time. It's the effort closest to a 750 m race swim.

Sweet spot on the bike

Long blocks at a sustained, steady effort: 3 × 15, 4 × 12 or 5 × 10 minutes. The session that raises your level without wearing you out.

The brick session

Bike then run, timed transition. In the build phase, the run stays easy; at the end of the plan, it's run at race pace.

Are your slots enough?

When you create your plan, Trainetic compares, discipline by discipline, the volume you do today with what the format requires. If something is short, it tells you which discipline is holding you back, and suggests a longer plan or a shorter format.

Five costly mistakes in a sprint

Going all out in the water. Over 750 m, the temptation is strong. But a start beyond your means costs you on the bike.

Riding too hard. Twenty kilometers flat out leave you with empty legs for the five kilometers that follow.

Improvising transitions. Helmet, race number, shoes: every move gets rehearsed in training.

Never linking bike and run. The feeling of the first minutes surprises anyone who has never experienced it.

Forgetting to drink. Even on a short format, a bottle on the bike keeps your energy up for the run.

Where these values come from

Every benchmark on this page comes from a public source.

The eight to twelve weeks are the length of published sprint plans, including those from TrainingPeaks and Garmin (twelve weeks).

Benchmarks from an American coach published by Triathlete: about four to five hours a week and two sessions per discipline for a sprint.

The ten-minute brick session for a beginner sprint and the transition under a minute: TrainingPeaks.

Sweet spot refers to an effort of around 88 to 94% of threshold power, according to the classification by Andrew Coggan.

Questions people ask before a sprint

How many weeks to prepare for a sprint?

Eight to twelve, for most triathletes. Your plan is built around your race date and starts from what you already do in each discipline.

How many hours a week?

Published benchmarks are around four to five hours for a sprint. Your plan doesn't set hours: it fills the slots you give it, and tells you whether that's enough.

Do I need interval sessions?

Yes, in the middle of the plan: threshold work in the pool, sweet spot on the bike, threshold and maximal aerobic speed (MAS) on the run. Never two hard sessions on the same day, and never two hard run sessions less than 48 hours apart.

How do I handle the bike-to-run transition?

By rehearsing it. Every brick session in your plan includes a timed transition: the goal is to get under a minute.

Is drafting allowed on the bike?

On short formats, it's often up to the organizer. The race rules specify it: read them before the race, it changes the way you ride.

Is a wetsuit mandatory?

It depends on the water temperature, measured on race day: the rules of the French Triathlon Federation (FFTRI) 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.

What if it's my very first triathlon?

The sprint is still accessible. If you'd rather start shorter, check out the first triathlon page.

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.
