Dorian Boulvin

Athletics (10km, Half Marathon, Marathon)

I am a 25-year-old long-distance runner and a member of the Runners' Lab Athletics Team. For me, running is not only a sport but also a passion and especially a lifestyle. I will always do everything to push my limits and make all my dreams come true! My ultimate goal is to participate in the Olympic Games at the marathon. In addition to my athlete career, I also have a master's degree in "Business Engineering" in 2021.

Clémence Beretta

Athletics (Heptathlon)

My name is Clémence Beretta, and I'm a professional athlete specialising in the 20 km race walk. I train once or twice a day, guided by a strong philosophy: focusing on the process rather than the outcome, while staying aligned in mind, heart, and body. Over the years and through 16 selections for the French national team, my approach has evolved significantly. I’ve developed a deep awareness of my body and sensations, prioritising my mental well-being and personal balance over an obsession with the stopwatch.
