Moore competed for the Olympic Club in the high hurdles and 220 yard hurdles into the 1940s. Toward the end of his running career in 1942, he was asked to help with a start up track and field event at Modesto Junior College. Moore served as the starter for the first meet for all but one race . . . the high hurdles, which he won. He had his running shorts on under his uniform and hastily changed to run.[6] He gained a reputation as a top track and field official.
For most of its 67-year run in Modesto Moore's name would go on to become synonymous with the event called the Modesto Relays. Moore did almost everything else to make the meet what it became, from attracting top name talent to adjusting the lights toward the track (rather than just the football field). Moore found sponsorship from S&W Foods that brought notoriety to the otherwise sleepy Central Valley town. When S&W dropped its sponsorship in 1994, Moore found a new sponsor in Coca-Cola.
At that first meet in 1942, "Dutch" Warmerdam set a world record in the pole vault with a bamboo pole. More than a decade later, Double Olympic Gold medalist, Bob Richards negotiated a $75 cash bonus, if he broke the meet record, which Moore agreed to. When Richards arrived, he discovered the meet record was the world record, which he never achieved in his career.
He was elected into the National Track and Field Hall of Fame as an Event Director in 1988.[7] In 2007, he was given the Howard Schmertz Lifetime Achievement Award by the U.S. Track Meet Directors Association.[8]
After his death in 2004, the Modesto Relays was renamed the "Tom Moore Modesto Relays."[9]
