Mills qualified for the
1964 Summer Olympics on the U.S. Track and Field Team in the 10,000 metres and the
marathon. The favorite in 1964 for the 10,000 m was
Ron Clarke of
Australia, who held the world record. The runners expected to challenge him were defending champion
Pyotr Bolotnikov of the
Soviet Union, and
Murray Halberg of
New Zealand, who had won the 5,000 m in
1960. Mills was largely unknown as a runner. He had finished second to
Gerry Lindgren in the U.S. Olympic trials. His time in the heats was a minute slower than Clarke's. Clarke set the tone of the race by using a tactic of surging every other lap. Halfway through the race, only four runners were still with Clarke:
Mohammed Gammoudi of
Tunisia,
Mamo Wolde of
Ethiopia,
Kokichi Tsuburaya of
Japan, and Mills. Tsuburaya, the local favorite, lost contact first, then Wolde. With two laps to go, only two runners were still with Clarke. He had run a world record time of 28:15.6, while neither Gammoudi nor Mills had previously run under 29 minutes. Mills and Clarke were running together, with Gammoudi immediately behind, as they entered the final lap. They were lapping other runners, and Clarke was boxed in down the backstretch. He pushed Mills once, then again. Then Gammoudi pushed them both and surged into the lead as they rounded the final curve. Clarke recovered and began chasing Gammoudi while Mills appeared to be too far back to be in contention. Clarke failed to catch Gammoudi, but Mills pulled out to lane 4 and sprinted past them both. His winning time of 28:24.4 was almost 50 seconds faster than he had run before and set a new Olympic record for the event. No American had before won the 10,000 m, nor has any other American come close until
Galen Rupp took the silver in the 2012 London Olympics. American television viewers were able to hear the surprise and drama as
NBC expert analyst Dick Bank screamed "Look at Mills! Look at Mills!" over the more sedate play-by-play announcer
Bud Palmer, who seemed to miss what was unfolding. For bringing drama to the coverage, Bank was fired, as it was considered improper at the time. After the race, Mills talked with Clarke and asked if he was straining as hard as he could on the final straight to the finish, to which Clarke replied, "Yes". Mills has stated that he tried to be relaxed during his final kick to the finish line and felt that helped him pass both Gammoudi and Clarke. Both Clarke and Mills ran the marathon after the 10,000 m event. Clarke finished in 9th place, and Mills finished in 14th, in 2:22:55.4, approximately two-and-a-half minutes behind Clarke, six-and-a-half minutes behind bronze medalist Tsuburaya and about 10 minutes behind winner
Abebe Bikila. ==Post-Olympics==
