Delroy Garrett is an Olympic track medalist whose career was derailed when it was found he used steroids. Dejected, Delroy joined the Triune Understanding to restore his faith. Triune leader Jonathan Tremont imbued Delroy with powers stolen from the former superhero 3-D Man. Delroy had no idea of the source of his new powers, thinking that the teachings of the Triune had simply unlocked his superhuman potential. Delroy became the costumed superhero Triathlon and the Triune's celebrity spokesman.
