's Triathlon Achievements.

Since the first Ironman in 2013, his career has been built around long distances, extreme formats, ultra-endurance, and challenges that go beyond mere rankings.

I discovered triathlon in September 2012. The following year, I finished the Ironman France in Nice, then the Embrunman a month later. Since then, my guiding principle has remained the same: to seek out races where the scenery, the duration, the weather, and the uncertainty matter just as much as the time.

Ironman events.

This list deliberately combines “classic” Ironman events with extreme formats covering the same or greater distances. This is where the story really unfolds: Nice, Embrun, then the European Xtreme Triathlons, followed by a more recent return to North American and international races.

2013

Ironman France Nice

First Ironman. The real starting point of my long-distance journey.

2013

Embrunman

Second finish at this distance, just one month after Nice.

2014

Celtman Xtreme Scottish Triathlon

44th overall, 2nd among French competitors, in 15 h 28 min 48 s. First major shift toward extreme triathlons.

2015

Austria eXtreme Triathlon

10th overall, 1st among French competitors, with a time of 15 hours, 33 minutes. One of the strongest results of the European season.

2016

44th in one of the most iconic events on the Xtreme circuit.

2016

2018

Swedeman

Another extreme race, continuing the tradition of the Celtman, Austria, Swissman, Evergreen, and Alpsman.

The Founding Challenge: UTN.

In 2016, the Napoleon Ultra-Triathlon went beyond the scope of a traditional race: a 16.4-km swim, a 550-km bike ride, and a 201-km run along the GR20 trail, completed in 5 days, 7 hours, and 54 minutes, to benefit the Adrien Association. It was a quadruple Ironman that was conceived, organized, and undertaken as a total adventure.

All About Triathlon.

Triathlon hasn't remained isolated. It has drawn inspiration from other disciplines: long-distance trail running, swimrun, cycling, open-water swimming, and marathons. These influences shape both the sport's profile and the races themselves.

The cycling portion, which is often the common thread running through these long days.

In the crosshairs.

The next steps are already marked on the calendar: Norseman 2026, Ultra-Lanzarote 2026, and then the ambitious Enduroman Arch to Arc in 2028. These aren’t just races to check off a list, but the logical continuation of a journey built around long, cold, mountainous, unpredictable, or downright unreasonable races.

His record reflects not so much a collection of medals as a lasting affinity for events that require endurance, adaptability, and the ability to keep going when the challenge becomes greater than oneself.
