For cars, such races seem to exist (have existed?) in the Netherlands:

These kinds of races seemed to be popular in the Netherlands because DAF (a Dutch manufacturer) produces the Variomatic transmission system

"Because the system does not have separate gears, but one (continuously shifting) gear and a separate 'reverse mode' (as opposed to reverse gear), the transmission works in reverse as well, giving it the side effect that one can drive backwards as fast as forwards. As a result, in the former Dutch annual backward driving world championship, the DAFs had to be put in a separate competition because no other car could keep up."
