Synching RaceClock...

The time you see ticking here is our "RaceClock". It runs with the accuracy of the internal clock of your computer, tablet or smartphone and is synched with our race time server. This results in accurate manual timing of races where start and finish are at different locations. Timing precision is not depending on the speed of your internet connection.
