A race to the bottom can occur in deregulated private industries as well.

The first race occurred in 1997 with less than 5000 entrants and each year the event raises funds for charity.

But the first major race didn't occur until 1929.

The more engaging race occurred on the women's side.

The most exciting race occurred on the second day of the Sweepstakes.

The last major race occurred at the track in 1981.

Actual home video footage of the accident was being recorded as the race occurred.

However, due to the slippery nature of the track, the race did not occur.

A second race occurred ten weeks later over the same distance.

The women's race, however, did not occur in the first and fifth editions.
