The limit is just me

MY LAST CHALLLENGE: MOVE IT! – Let’s make a difference together!

From 24 September to 23 October 2026, I ran 30 marathons across Baden-Württemberg in 30 days, accompanied by more than 19,000 fellow runners. This charity campaign in aid of the ‘everyday heroes’ in clubs and voluntary roles raised a total of 835,000 euros in donations, supported by contributions from VR-Gewinnsparen and regional mini-challenges.
