Mannheim's Michael-Hoffmann-Stadion hosts the Sterntaler Spendenlauf, an annual charity run focused on laps, sponsors, and participation over finishing times. The run officially begins at 10:00 AM, with stadium activities continuing until late afternoon. Joey Kelly is the patron, and the event welcomes a diverse group of participants: professionals, amateurs, hobbyists, parents, children, and extended family all run together.
Participants can complete laps within the stadium or join virtually from any location, selecting their own routes through natural or urban settings. The concept is straightforward: set your own pace, gather sponsor pledges, and accumulate distance for the cause, not for personal records. A key tradition is the event's welcoming atmosphere, where elite runners interact with children earning lap ribbons and wheelchair users compete alongside others. The stadium provides entertainment and refreshments from MTG friends, making the day a combination of a run and a community event.
