Arthur began trail running in 2013 and ultra-distance races in 2016. Over the years, he has consistently proven himself in grueling competitions, including TDS by UTMB®, Istria 100, and Hoka UTMB® Mont Blanc. His preparation includes long high-altitude runs, technical terrain drills, and mental training to strengthen focus and resilience.

A crucial tool for his training is Shokz OpenRun Pro 2, which allows him to listen to music or podcasts while staying aware of ambient sounds — essential for safety and situational awareness on remote trails. Often wearing them for 12-hour training sessions, he maintains rhythm, motivation, and presence throughout.

Arthur embodies the Shokz "Be Open" mindset: fully connected, present, and motivated. Beyond competitions, he embraces self-imposed challenges to push limits and discover new capabilities. From alpine passes to ultra-distance finishes, Shokz supports him in combining performance, safety, and enjoyment, transforming every run into an opportunity for growth. His journey reflects that determination and smart preparation, paired with the right technology, can elevate both performance and experience in ultra-trail running.
