Free sprint triathlon training plan: 10 weeks to your first race

A free 10-week plan for a sprint triathlon (750 m, 20 km, 5 km): swim, bike and run sessions, transitions, strength and tapering.

The sprint triathlon (750 m of swimming, 20 km of bike and 5 km of racing) is the ideal distance to debut. This free 10-week plan is designed for those who no longer swim, pedal and run a little and want to finish their first race with good sensations. To plan a full season, see how to plan your triathlon season.

Rapid response: For a sprint triathlon in 10 weeks, train about 6 sessions per week: 2 swimming sessions, 2 bike sessions and 2 race sessions, with a combined bike and race session (transition) each week from the specific phase. Most of it, at mild intensity; last week, less volume and some pace.

Before we start

  • You can swim about 400 m in a row, even if it's slow.
  • You can pedal about 45 minutes and run about 20 minutes in a row.
  • You have access to a swimming pool and a bike in good condition, with helmet.

If you do not reach these minimums, spend a few weeks on each discipline separately.

The 3 phases of the plan

PhaseWeeksObjective
Base1-4Swimming technique, soft volume, general strength
Specific5-8Race pace, combined sessions, transitions
Setting up9-10Less volume, maintain intensity, race

SaturdaySoft bike 60-75 minCombined: bike 45 min + race 15 minVery short combination or break (week 10: race)
SundaySoft race 35-40 minSoft race 40 minSoft rolling or running

Week 4 and week 8: reduces volume to assimilate. Always warm up before quality sessions.

Transitions: train them

  • Always place the material in the same order.
  • Practice getting out of the water and switching to the bike at home.
  • In the combination, go out for a run just as you get off the bike: you learn how to manage heavy legs.

Why the plan is made like this

  • Soft base: In endurance sports most of the volume is done at low intensity (Seiler, 2010).
  • Specific practice: In triathlon, getting well prepared requires training every discipline, transitions and race strategy (Etxebarria et al., 2019).
  • Setting up: reduce volume and maintain intensity before competing (Bosquet et al., 2007). If you follow the load, look at it in CTL, ATL and TSB.

What a Coach Says

"In a first sprint, transitions and the head are the most trained. To practice changing from bike to race takes away a lot of fear." — Marc Bañuls, coach with more than 15 years of experience

Frequently Asked Questions

How long does it take to prepare a sprint triathlon?

If you swim, pedal and run a little, 10 weeks is a reasonable time to end with good sensations.

How many hours a week do I need?

With about 6 short sessions per week is enough for a sprint; the duration of each depends on your level.

What is a combined training?

A bike session followed by a race without pause, to get used to the legs to change.

Do I need a triathlon bike?

No. For a first sprint, a good road or mountain bike and an approved helmet are enough.
