The chilean brand Oxford has created a giant treadmill for 10 runners at the same time. Towering 4,5 meters tall, 3 meters wide, 6 meters long, and featuring a 12hp electric motor, it has power to move 2 tons, and reach speeds from 1km/h to 16km/h. With this project, Oxford created the first marathon on a treadmill: 10 participants run, and as time goes by, the speed picks up, forcing the contestants to leave the race. The last one standing becomes the winner. Site:
