Where do the pacers gather?
There is no central gathering point where pacers meet before the race. They go directly to the starting area's. For the full marathon this is in the Olympic Stadium, for the half marathon on Stadionweg. The pacers take their places in the start area's that correspond to their target times. The target times are listed below. The pacers will be recognizable by a flag with the target time they will run. Well before the start they are present in their start boxes, where they line up per target time (fastest time at the front of the box, slowest time at the back).
This service - apart from the standard registration fee for the even itself - is completely free!
