What the two do not know when they set out: Today the organizers have come up with a special challenge. In contrast to the usual procedure, the Gazelles receive the coordinates for Checkpoint 8 when starting at Checkpoint 6. They have to use these coordinates to determine the location of Checkpoint 7, the first of the day, on their own. Astrid and Sabrina fall into the trap and head directly for Checkpoint 8. They race 90 km in the wrong direction before they notice their mistake. Once they are finally back on the right course, they try to take a shortcut, promptly get stuck and are truly pushed to their limits.
