What the race asks of your training
A draft-legal sprint
Drafting is allowed on the 20 km bike, ridden in three loops. Swimming hard at the start to leave the water with a group, then knowing how to ride in a pack and respond to surges, matters as much as raw power. A few group rides are a must.
No aid station on the bike
There is no aid station on the bike leg, one on the run and one at the finish. On a sprint one bottle is enough, but you need to be used to drinking while riding in a group, and the 3 pm start in June can be warm.
Fast from the first minute
Over 750 m, 20 km and 5 km, everything happens at high intensity. VO2max and threshold run sessions, and short bike-to-run bricks at 5 km pace, prepare you to run fast straight out of transition.
Be ready for a duathlon
If the swim cannot go ahead, the race becomes a duathlon: 2.5 km run, 20 km bike and 5 km run. A few run-bike-run sessions in your build-up mean you will not be caught out.
The plan below prepares the Triathlon S open format, for an athlete at intermediate level with 5 days available per week. Until the official date is out, the example is set for June 2027.

Why this plan works
Science-based periodisation
Base → build → specific → taper, with a recovery week every 3 to 4 weeks. Load goes up, but never two hard weeks in a row without a breather.
Paces, not vague feelings
Every session has target zones (pace, HR) computed from your MAS or a reference performance. A MAS test is built into the plan if you don't know yours.
Three disciplines, one load
Swim, bike and run are planned together: brick sessions, key sessions spread out, and a coherent total load week after week.
A plan that listens
After each session you rate how it felt (RPE). Too hard? The plan eases what follows. Skipped a session? It reschedules or absorbs it.
On your watch
On Garmin with the Endu app, on COROS by direct sync: the guided workout shows up on your wrist, step by step.

Frequently asked questions
- When is the 2027 Laval triathlon?
- The 2027 date is not announced yet. The 36th edition took place on Sunday 14 June 2026 at the Square de Boston, with the open sprint at 3 pm.
- Is there an Olympic distance in Laval?
- No. In 2026 the race open to all was a sprint (750 m, 20 km, 5 km), draft-legal, solo or relay.
- How much is the entry fee?
- In 2026: €29 solo, €32 for a relay, plus the FFTri Licence Expérience for non-licensed athletes and Klikego fees.
- Triathlon de Laval: how many weeks of preparation?
- For an athlete at intermediate level, Endu builds a 11-week preparation. If your race is closer, the plan compresses phases while keeping the taper; if it's further away, it lengthens the preparation, and when the gap is large the preparation starts right away, gently and at your current volume, before building up.
- Is this plan well built?
- Pass at Endu’s plan check, the same as for any plan: 18 of 18 checks passed. A 11-week build (recommended minimum: 6); a longest run never more than 9% above the previous month’s; 83% of the time at easy effort; a taper cutting volume by 65% in race week. The rules and their sources are public on endu.fr/en/controle-technique.
- How many sessions per week?
- This example has 5 sessions per week. You choose 3 to 7 training days and the exact days (e.g. Tue, Thu, Sat, Sun): the plan sticks to them.
- I'm a beginner, is this plan for me?
- The plan adapts to your declared level (beginner to semi-pro): starting volume, progression and intensity change. Endu also offers a "Discovery" mode without a race to build a base first.
- Can I follow sessions on my watch?
- Yes, on Garmin and COROS. On Garmin, the Endu app (Connect IQ Store) shows today’s session and starts it as a guided workout. On COROS, link your account from your profile: your running, trail and cycling sessions land in the watch calendar. Other brands are not supported yet.
- How much does it cost?
- 14-day free trial, then €7.99/month with no commitment or €59.88/year (€4.99/month). Unlimited objectives and sports.
