Ironman 70.3 Vichy: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 21-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 6 sessions per week. You choose 5 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

Swim: one 1.9 km loop in the calm water of Lake Allier; transition on the sandy car park by the lake. Bike: one 90 km loop. The first 2.5 km follow the lake, then the road crosses the Limagne plain, passes Puy-Guillaume (chicanes) and enters the Livradois-Forez regional nature park via Châteldon (km 35). A 9.5 km climb at 3.7% up to La Guillermie, the high point of the course, a two-part descent to Ferrières-sur-Sichon, technical sections to Arronnes (km 69), a long gentle downhill along the Sichon to Cusset, then back into Vichy over a last 40 m rise and down the Route de Creuzier. Run: two flat laps around Lake Allier and through the parks, passing through the finish arena on each lap.

What the race asks of your training

The climb to La Guillermie

After a fast stretch across the Limagne plain, ideal for settling into the aero position, the bike enters the Livradois-Forez and climbs to La Guillermie, the high point of the course: 9.5 km at 3.7% on average, in the shade. Climbs of 25 to 40 minutes at or just below threshold, within your long rides, prepare you for this effort.

Technical descents

After the summit, the organisers flag a tricky entry into Ferrières-sur-Sichon, fast descents mixed with technical sections down to Arronnes (km 69), then a long gentle downhill to Cusset. Working on your descending lines and knowing how to push on the false flat saves time without costing energy.

A swim sometimes without a wetsuit

IRONMAN lists an average water temperature of 22 °C, but recorded 25 °C in 2024: above 24.5 °C, wetsuits are banned. A few long swims without a wetsuit, in open water, keep you from being caught out in the middle of August.

A flat half marathon to finish

Two flat laps around Lake Allier and through the parks of Vichy. Bricks of hilly riding followed by a steady run teach you to find your legs quickly off the bike.

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 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
