With the news that RaceRanger will be introduced at Challenge Roth next year – and that is not the first Challenge Family race to use the anti-draft system – it is interesting to take a closer look at the system. That brought us to this (incidentally year-old) video from GTN. Good to know is that RaceRanger actually evolves almost constantly, but the video gives you as an athlete a good idea of what to expect in the near future.
