The Transeurope Footrace Project: Longitudinal data acquisition in a cluster randomized mobile MRI observational cohort study on 44 endurance runners at a 64-stage 4,486km transcontinental ultramarathon. In 2009, the trans-European race was conducted by Bari to the North Cape. A research group accompanied the runners with a mobile MRI together with many other investigations.
