The Zürich  Marathon Timekeeper is Race Result. The time measurement is done by means of a transponder integrated in the star number. The Transponder/ Start number doesn't have to be returned. (all category)

​

The Teamrun teams, along with the four starting numbers, receive a extra relay band (Team start number). The relay tape must be handed over in the transition zones and must be worn at the back. The time is not stopped! 

Personal time measuring chips cannot be used.
