biography

Developer by day and ultratrail runner the rest of the time, Victor went from road races to long-distance mountain races in just a few years.

In 2026, he completed his first 100-mile race at Alsace Grand Est by UTMB: 158 km and 5,100 m of elevation gain in 24h30.

He approaches this progression like his digital projects: with curiosity, method, and a desire to understand. Alongside his training, Victor develops free tools for runners: pacing plans based on GPX tracks, time estimates, race review sharing, and Ultra Destin, his simulation game dedicated to ultratrail.

No elite-athlete posturing: Victor simply shares his progress, successes, mistakes, and everything he learns along the way.

“Every race asks me a question. Every tool I develop answers it.”

Landmarks & field tips

• Calcule ton allure avant, pas pendant : sur un 100 km, l'erreur vient rarement des jambes, elle vient d'un plan de marche improvisé au kilomètre 12.
• Prépare la nuit comme une discipline à part : sur mon premier 100 miles, les heures d'obscurité ont pesé plus lourd que les 5 100 mètres de dénivelé.
• Le plat n'est pas une excuse : je m'entraîne en région parisienne et je cours en montagne, ça ne remplace pas les Alpes mais ça suffit à finir un 100 miles.
