The Kentucky Derby Museum, along with the 2015 Secretariat Festival and Secretariat.com, have applied to Guinness World Records as it attempts to create the largest horseshoe.

Expected to weigh nearly a half ton, the shoe, a replica of the one worn by the 1973 Triple Crown winner, was cast by Louisville-based Eagle Sign & Design Inc. and Thoro'bred Inc., which made Secretariat's originals. It will be unveiled at 1 p.m. Sept. 20.
