Rácer. n.s. [from race.] Runner; one that contends in speed.

His stumbling founder'd jade can trot as high
As any other pegasus can fly;
So the dull eel moves nimbler in the mud,
Than all the swift-finn'd racers of the flood. Dorset.

A poet's form she plac'd before their eyes,
And bade the nimblest racer seize the prize. Pope.
