With the 4-Lakes Duel, an unofficial boundary stone is set between Engelberg-Titlis and Melchsee-Frutt. Two teams, each with 100 runners, compete against each other.
One team starts on Trübsee and the other team on Melchsee-Frutt. Both complete the same course in opposite directions and will thus cross paths with their opponents along the way.
