Secretariat's Horseshoes

Origin
Secretariat (March 30, 1970-October 4, 1989) was an American thoroughbred racehorse who set multiple records and was the first Triple Crown winner in 25 years (1973). Near the end of his life, Secretariat was afflicted with laminitis (A condition that affects horses' hooves that is often incurable), rendering him unable to walk

Effects
The horseshoes each contain the speed of Secretariat, and give that speed to anyone who holds one of them. However, once the user lets go of the horseshoe they will be rendered unable to walk for three times as long as they used the Artifact
