Spanish athlete and creator Verdeliss takes endurance to the extreme with Decathlon’s Reto 24h Running running nonstop for 24 hours on a treadmill in Madrid to debut the new Kiprun Kipride Max, the brand’s most cushioned daily trainer.

​Spanish athlete and content creator Estefanía Unzu Ripoll, widely known as Verdeliss, has completed one of the most demanding challenges of her career: running for 24 consecutive hours on a treadmill without rest.

​The initiative, titled “Reto 24h Running con Verdeliss,” is organized by Decathlon to introduce its new Kiprun Kipride Max model, described as the brand’s most cushioned daily training shoe.

​The challenge started at 19:00 on Wednesday, February 25, and will run until 19:00 on Thursday, February 26, inside the storefront window of the Decathlon Nuevos Ministerios location on Calle de Orense in Madrid.

​The Navarra-born runner arrived at the challenge in peak form.

​In recent days, she set a personal best at the Maratón de Sevilla with a time of 2:45:39 and clocked 1:20 at the Media Maratón de Urola. Now, instead of racing the clock over 42 kilometers, she will test her endurance over an entire day.

​There is no minimum distance requirement. The objective is simple in concept but extreme in execution: keep running. The effort is designed to push both physical stamina and mental resilience, especially in the late-night hours when fatigue sets in.

​During store hours, visitors could join symbolically by running on a second treadmill, turning the event into a collective experience for Madrid’s running community.
