When is the 2027 Bordeaux triathlon?

The 2027 date is not announced yet. The event used to be held at the end of June, and the club page still mentions “the last weekend of June”; in 2026 it took place on Saturday 5 and Sunday 6 September. 2027 could therefore fall in late June or early September.

When does registration open for the 2027 Bordeaux triathlon?

Not announced yet. In 2026 it opened on 14 February on ProTiming, from the official website, until places ran out.

Where is the Bordeaux triathlon held?

At Bordeaux-Lac, in the Jallère district. Parking is limited: the organisers advise coming by bike or by tram.

Is a wetsuit allowed?

It is mandatory below 16 °C and banned above 24.5 °C.

Triathlon de Bordeaux: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 15-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.

How many sessions per week?

This example has 5 sessions per week. You choose 4 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.

The 2026 course

Everything takes place at Bordeaux-Lac, in the Jallère district, with a mass start in the water, men and women separated. The M swims 1.5 km in two loops, rides 40 km in three laps on closed roads, then runs 10 km in one loop. The L swims 1.9 km in two loops, rides three 30 km laps, partly on open roads and partly on closed roads where you ride on the left, then runs three 7 km laps. In 2026 the M started on Saturday at 8:30 am and the L on Sunday at 8 am.

What the race asks of your training

A date to watch

The race was held at the end of June until 2025 and in early September in 2026. For late June, most of the build-up falls in April and May, with the first open-water swims just before the race. For early September, it falls in mid-summer: keeping a threshold ride and a bike-run brick every week, early in the morning during the holidays, matters more than volume.

Drafting on the M, not on the L

On the M you can ride in a group, but time-trial bikes and aero bars are banned. On the L everyone rides alone: bike training differs, group rides with surges for one, long threshold efforts for the other.

A mass start

The swim is a mass start, with men and women separated on the line. A few open-water swims with others, practising a fast start then settling into your own pace, avoid being caught out in the first 200 m.

The cut-offs

On the M, you must be out of the water within 1 hour and finish the 2nd bike lap 2h30 after the start; on the L, 1h10 and 4 hours. That is generous for most triathletes, but a timed swim-bike session late in your build-up is reassuring if you expect to be near the back.

The plan below prepares the Distance M format, for an athlete at intermediate level with 5 days available per week. Until the official date is out, the example is set for September 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.

“For triathlon, having all three sports in the same schedule really makes my life easier. I spend less time organising my training and I still enjoy following it just as much.”
Maxime · Triathlon
“At first I just wanted to try it. Now checking the next day’s session has become my little evening ritual 😊”
Sarah · Triathlon
“I used to spend more time looking for a plan than following one. Now I have my sessions, I know what to do and I stick to it. Really glad I tried it.”
Thomas · Running
“Training for my first half marathon and honestly, I’m getting into it! I even look at my next sessions ahead of time, when before I was mostly looking for an excuse not to go out 😂”
Camille · Running
“Simple to follow and really handy with the watch. I start my session and off I go.”
Julien · Running
“I took Endu to prepare a trail race with friends. I really like having my week already organised: it motivates me and I enjoy my runs more.”
Émilie · Trail
“What I like is no longer asking myself a thousand questions before going for a run. I follow the plan and I enjoy training.”
Nicolas · Trail
“With work and the kids, I thought I’d struggle to follow a plan. In the end, having a structure helps me a lot. Running has found a real place in my week again, and it feels good!”
Julie · Trail
“A good find to prepare my swimrun! It’s nice to find a plan for this sport. I’ve recommended it to my teammate.”
Antoine · Swimrun
“I run more regularly and, above all, with more desire. For that alone, I’m delighted.”
Laura · Swimrun
