The competition takes place as a part of the Streetlife Festival at Leopoldstraße.
Due to the Streetlife-Festival the whole street from the south of Odeonsplatz to the north of Münchner Freiheit will be closed to cars. So you need to expect some traffic obstructions within some radius. That's why the best way to come is with public transportation or with skates.
The next subway station is Odeonsplatz (U3, U4, U5, U6).
