TVS News AI, editorially supervised, presents Arda Saatçi trades ultramarathon for catwalk – runway debut alongside Heidi Klum in Paris.

Long distances, extreme routes, every step counts – that's the world of Arda Saatçi. On Monday evening, the extreme athlete leaves his familiar stage and steps onto entirely new terrain: the catwalk. At the L'Oréal Paris show during Paris Fashion Week on September 28, 2026, the 29-year-old celebrates his runway debut – alongside world stars like Heidi Klum and Kendall Jenner.

The Monday evening show is one of the highlights of the fashion calendar. Saatçi, otherwise known for spectacular ultramarathons, trades his brisk running pace for a noticeably more leisurely stride on the catwalk. For the athlete, it's an excursion into a world that differs greatly from his previous projects – and that's exactly where the appeal lies for him.

Why Arda Saatçi is stepping onto the catwalk

Despite lacking runway experience, Saatçi wants to take on the unfamiliar task and present a new side of himself at the big show. In conversation with Bild, he sums up his motivation.

This is completely new territory for me! But that's exactly what excites me

Heidi Klum and Kendall Jenner as runway partners

Walking alongside him at the spectacle are internationally known models and stars like Heidi Klum (53) and Kendall Jenner (30). The L'Oréal show regularly brings well-known personalities from the modeling world, sport, and entertainment onto the catwalk – Saatçi joins a line-up of celebrities who appear on the runway outside their core discipline.

From ultramarathon to catwalk – what's behind it?

Saatçi is known for endurance and spectacular running ventures. The leap from the world of ultramarathons into the fashion industry is unusual – but it also shows how fluid the boundaries between sport, entertainment, and fashion have become. For the 29-year-old, the appearance is a welcome change and a chance to prove himself in an environment that has little in common with his previous projects.
