The Henley-on-Todd Regatta (also called the Todd River Race) is a “boat” race held annually in the typically dry sandy bed of the Todd River in Alice Springs, Australia.
Every year in the spring, around September, the town holds a mock regatta which large numbers of locals and tourists attend. Food and drink are sold at stalls, “no fishing” signs are put up, and the celebration takes all day.
It is the only dry river regatta in the world; thus, it is the only regatta ever cancelled because of wet weather and there was actually water in the river.
