The German clan Xeon will host a 6 hour race for the 4th time. The event is driven in Laps-mode in teams of 2 players on 1 map where both players need to play 3 hours each. The ranking is decided by the amount of checkpoints passed during the 6 hours of total play. Just as in the 24h races, the map will be revealed when the race starts.
You got until August 30th 21:00CEST to sign up, and the race starts September 1st 12:00CEST.
The organizers will also provide a stream for you to follow the event.
