The organiser puts the first and third exchange on the Neu-Ulm bank and the second on the Ulm bank, all at the Offenhausen footbridge. A runner may take two legs, and the last 200 metres to the finish may be run together, with the fourth runner picked up at the fountain at Glöcklerstrasse and Hirschstrasse.
