Starting block 1 (Groups 1A, 1B, 1C) will leave exactly at 6:45 am. All cyclists of the first starting block get the same starting time (6:45 am). The qualification criteria for a place in the first starting block, defined by the race director, can be found on the public notice board.
All the other participants start the marathon by using the Real Timing System: the time runs as soon as you pass the starting line. There are 8 more timekeeping points along the course; they must be passed by all participants. With one missing timekeeping information the cyclist will be disqualified. Every cyclist has to pass the timekeeping areas/lines correctly and control it for himself immediately. The clocks displayed on several information boards – race director, presenter, closing car – measure the time passed from the official starting signal. In the start and finish area the exact time is displayed.
