About this study

Up to 120 experienced marathon runners will participate in the "Berlin Beat of Running Study" and will wear a transportable electrocardiogram (ECG) recorder at least 24 hours before, during and 24 hours after the BMW-Berlin Marathon. All participants will undergo brain MRI examinations to detect cerebral lesions within days before and after the marathon race, respectively. Moreover, serial blood samples will be taken a few days before, immediately after as well as a few days after the BMW-Berlin Marathon.
