The Thoroughbred Stayer is a subtype of the Thoroughbred horse. It has higher endurance than the other two subtypes, and therefore can keep up a high speed during the entire race.

Thoroughbred Stayers come in the colors of bay, brown, black, chestnut, grey, and cream-diluted. In rare cases, they can be roan or dominant white as well. Their coat is usually solid, but many Thoroughbreds have sabino coat, though this sabino pattern is caused by various white-spotted genes and not by Sabino 1. Additional patterns that exist in this breed are frame-overo, splashed-white, and manchado. Tobiano doesn't exist in this breed. Thoroughbred Stayers stand between 15.1hh and 17.2hh.
