The competitions are always held at two locations: In the Letzigrund stadium and in the heart of the city at Sechseläutenplatz. The inner-city location directly in front of the opera is something very special for athletes and spectators. The backdrop is impressive, the proximity to the competitions unique and the athletics fever can be felt everywhere. The grandstands, podiums and all other event structures that were necessary to transform the busy square into a temporary stadium were erected by the NUSSLI team in just two days and completely dismantled again similarly quickly after the event.
