Random race track and distance races are not selected correctly

Description

With the update below, some races now have randomized racetracks and distances, even in the same race.

Even with the same race name, the racetracks and distance are randomized, so the score changes depending on the distance aptitude and status, and it keeps looping trying to select a race that doesn't exist.
