IRONMAN 70.3 Vichy 2027
A lake swim in the middle of a Belle Epoque spa town, a rolling bike through the Allier countryside, and a run along the riverbank.

44 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Build my complete road
Three honest inputs. Your first answer appears here; no email wall and no generic plan.
Course risk: The rolling course makes bike restraint and run durability decisive.
Build my complete road.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“A proper French endurance town with a lake swim right in the centre. Rolling rather than flat, so hold something back for the second half of the bike.”
The race
The evidence, translated into a decision.
This is not another difficulty score. It connects verified course evidence to the athlete constraints you have already shared with Unbroken.
Choose this race if you value a demanding bike with a more runnable final leg.
Think twice if your available week cannot protect bike durability and recovery; the GPX-derived bike profile shows 1142m of gain.
Build durable climbing, low-cadence strength and disciplined descents, then practise running smoothly after variable bike load.
The course
IRONMAN publishes no route file for this leg, so there is no course map to draw from.
One loop of the Allier, calm and wide, usually swum as the sun comes up. River water at dawn is colder than the forecast suggests, so get in before the start if you can.
Interactive bike route in the Course Lab above ↑ Drawn from the official GPX file, checked against this leg's distance.
One loop through Châteldon and the green Livradois-Forez, including a steady shaded climb to La Guillermie and a mix of descents and false flats afterwards. The false flats are where people lose the run.
Interactive run route in the Course Lab above ↑ Drawn from the official GPX file, checked against this leg's distance.
Two flat, fast laps around the Lac d'Allier and through the parks of Vichy. Compact and well supported, and easy to run too hard early because it feels so comfortable.
Not yet confirmed for this edition: bike elevation gain, aid station spacing, water temperature. We publish these only once they are on the official course page, so check there before you pace off anything here.
