(SOUNDBITE) (French) CO-ORGANIZER OF THE VORTEX RACE, CHLOE BACHTOLD, SAYING: “It's pretty crazy, it's really like a 3D stadium, so we have this kind of atmosphere where down below there's music, people cheering everywhere, it resonates in this building and people are quite lost because they're going up but they don't feel it because it's only a 1% slope, so people are running but don't really realize they're going up. They often don't know where they are in the race, they're running but they don't know if they're on floor 1, 2, 3, 4. So we put up signs to help them - second lap, fourth lap - to help them get their bearings. And really you have this sound going up, this encouragement all the way and the atmosphere is pretty crazy.” 17. (MUTE) DRONE SHOT OF VORTEX BUILDING AT NIGHT 18. RUNNER STARTING HIS RACE 19.

(SOUNDBITE) (French) FORMER EPFL STUDENT, MIGUEL GOMES, SAYING: “I didn't feel the climb itself, but it was more the feeling of seeing the little light at the end approaching. You see it approaching, but you never get there. But no, the climb itself is really very calm, the three-kilometers, I don't know 20 meter climb, it's very, very easy. It's great.” 25.

(MUTE) DRONE SHOT OF PEOPLE RUNNING UP THE INTERIOR RAMP OF THE VORTEX BUILDING STORY: Two thousand people ran up the interior ramp of the Vortex on Thursday evening (October 16), an iconic circular building at the University of Lausanne, as part of race organized by the EPFL' students. “The race is incredible, going around in circles like that, I think it was original. It was tough, but yeah, only good feelings,” said a student from Geneva, Ricky Van Den Ouweland, who ran the 7km race. The first edition of the Vortex race took place in 2021 and only allowed students. As years passed, the race has opened up to various profiles, like 33 year old Geneva resident, Alex Rueff. “As soon as you arrive here, a crazy atmosphere, everyone screaming and in fact with the sound effect it resonates. So you cannot not be in the mood,” he said after crossing the finish line on the 8th floor of the building. Located on the Lausanne Campus, the Vortex is a residential complex designed to accommodate students from the Swiss Federal Technology Institute of Lausanne, UNIL and EPFL. It offers almost 1,000 living spaces, ranging from individual rooms and studios to shared apartments for groups. In addition to housing, the building features around 2,400 m² of communal areas, which include a multipurpose hall, a kids' zone, dining venues, cultural and social spaces, workshops, and retail outlets. The Vortex stands out for its distinctive ring-shaped design, featuring a continuous 2.8 kilometer ramp that connects all the residential units throughout the structure. The building spans 137 meters in diameter, rises to a height of 27 meters, and consists of eight gradually ascending levels arranged in a spiral layout. “People are quite lost because they're going up but they don't feel it because it's only a 1% slope, so people are running but don't really realize they're going up,” co-organizer of the Vortex Race, Chloe Bachtold told Reuters. The construction of the Vortex, which cost 156 million Swiss francs, ended in 2019 and in January 2020 it welcomed young athletes for the Winter Youth Olympic Games. Just a few months later, in response to the COVID-19 crisis, it was repurposed to provide emergency housing for healthcare professionals. By August of the same year, the building began fulfilling its long-term role, welcoming its first cohort of students from UNIL and EPFL.
