1896, originally in reference to horse-races, from also + past tense of run (v.). Probably from the way non-placing horses were listed in race results.
Loser, failure, unsuccessful individual, as in Jane feared that her candidate, a terrible speaker, would end up as an also-ran, or As for getting promotions, Mark counted himself among the also-rans. This term comes from racing, where it describes a horse that finishes in fourth place or lower or does not finish a race at all. It first appeared in the 1890s in published racing results, and has since been transferred to losers in any kind of competition, and also more broadly to persons who simply don't do well.
