When is IRONMAN Vichy 2027?

On Sunday 22 August 2027, according to ironman.com, the same day as IRONMAN 70.3 Vichy. The 2026 edition was held on 23 August, with a 7 am start.

How much is the entry?

€887.04 all in as of 17 October 2026. The price rises as places are sold, and there are no relays on the full distance.

How much climbing is on the bike?

About 2,000 m of climbing over 180 km according to the 2026 athlete guide, with La Guillermie (9.5 km at 3.7%), hills between Lapalisse and Châtel-Montagne and a last 40 m rise before Vichy.

What are the cut-offs?

In 2026: 2h20 for the swim, km 61 by 12:30 pm, km 107 by 2:40 pm, bike finished within 10h30, km 31 of the run by 9:50 pm and finish within 16 hours.

Ironman Vichy: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 25-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 7 sessions per week. You choose 6 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?

Not as a first long race: if you declare a beginner level, Endu flags it. Aim for a shorter race of the same kind first; Endu builds that preparation too.

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.

Ironman Vichy 2027: date, course and training plan

226 km · swim 3.8 · bike 180 · run 42.2Vichy2027 edition: 22 August 2027

IRONMAN Vichy is the full IRONMAN distance raced in late August in the spa town, on the same day as IRONMAN 70.3 Vichy. The full distance returned there in 2026: a 3.8 km swim in the Allier, 180 km of riding through the Limagne, the Livradois-Forez and the Montagne Bourbonnaise, then a flat four-lap marathon around Lake Allier. The 2027 edition takes place on Sunday 22 August.

A demanding distance: it is wiser to have finished a shorter race of the same kind first.

The 2026 course

Start at 7 am on the banks of Lake Allier, for one 3.8 km swim loop in the Allier; transition on the sandy car park by the lake. Bike: one 180 km loop. The first 2.5 km follow the lake, then the road crosses the Limagne plain, through the chicanes of Puy-Guillaume and Châteldon (km 35), climbs to La Guillermie (9.5 km at 3.7%, the high point of the course), descends to Ferrières-sur-Sichon and Arronnes (km 69) and runs along the Sichon to Cusset. Second half: about twenty fast kilometres via Bost and Billezois (personal needs station), Lapalisse, the hills from La Bruyère to La Croix Rouge (km 124 to 132), Châtel-Montagne and Le Mayet-de-Montagne, then back down the Sichon valley and over a last 40 m rise before the descent of the Route de Creuzier. Run: four flat laps around Lake Allier and through the parks of Vichy.

What the race asks of your training

2,000 m of climbing spread over the whole day

After the Limagne plain, the climb to La Guillermie is 9.5 km at 3.7%. But the end is more draining: rolling “roller-coaster” hills between La Bruyère (km 124) and La Croix Rouge (km 132), on a rough and barely shaded road, then the climb to Châtel-Montagne. Long rides of 5 to 6 hours should keep climbs in the second half, not only at the start.

A late-August swim, sometimes without a wetsuit

IRONMAN lists an average water temperature of 22 °C, and the athlete guide bans wetsuits above 24.6 °C. Over 3.8 km, swimming without neoprene makes a big difference: do several long swims without a wetsuit, in open water, in the middle of summer.

Bike cut-offs to keep an eye on

With a 7 am start, you must reach km 61 by 12:30 pm and km 107 by 2:40 pm. If your bike pace is tight, the swim and the first transition matter: ten minutes saved in the water gives you a margin before La Guillermie.

A build-up through high summer

For a race on 22 August, the biggest weeks fall in July, often in the heat. Do your long sessions early in the morning and keep a bike-to-run brick every week: the flat four-lap marathon is run at a steady pace, at the top of your easy endurance range.

Endu runs its own plans through the plan check open to everyone: same public rules, same thresholds, same sources. The rules and their sources, and a check of your own plan.

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.

4.8/5

“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
