In one of the most infamous moments in Olympic history, American favorite Mary Decker stumbled during the 3000m final, allegedly colliding with British debutant Zola Budd. While Decker was favored to win, the chaotic finish resulted in her elimination and a silver medal for Budd, shocking the world.
While Bolt was favored, his victory was an upset in magnitude as he broke his own world record by 0.01 seconds with a seemingly effortless drive. At the time, many experts doubted a sprinter could maintain such speed through the 800m mark, making his dominance a surprising triumph.
British athlete Derek Redmond tore his hamstring during the 400m heats but refused to quit. With his father joining him on the track to finish the race, the moment became an iconic display of spirit rather than competitive upset, though it overshadowed the official winner's medal ceremony.

Although Johnson was disqualified, Lewis's gold medal was initially uncertain as he trailed Johnson for much of the 100m final. The subsequent scandal and disqualification turned Lewis into an unlikely champion, highlighting the fragility of success in sprinting where margins are razor-thin.
David Rudisha shattered the 800m world record by a massive 0.26 seconds in the Olympic final. This performance was considered nearly impossible at the time, defying physiological expectations and leaving competitors and analysts in stunned silence, marking a paradigm shift in middle-distance running.
Felix defeated Shelly-Ann Fraser-Pryce, a dominant sprinter, in the 200m final. This was a significant upset as Fraser-Pryce was the favorite and had just won the 100m. Felix's tactical race and superior endurance in the latter stages secured her an unexpected but well-deserved gold.
Bekele won the 10,000m by a stunning 3 seconds, a huge margin in distance running. His performance was so dominant that it silenced critics who doubted his Olympic capability compared to his track records, marking his emergence as the definitive king of long-distance running.
Hassan won both the 5000m and 10,000m, along with a bronze in the 1500m. Her 10,000m victory was an upset as she was not the primary favorite in that event, yet her tactical brilliance and versatility stunned the field, proving her exceptional adaptability and strength.
Brisco-Hooks became the first woman to win both the 200m and 400m at the same Olympics. Her victory in the 400m was particularly surprising as she was not heavily favored, showcasing a rare combination of speed and endurance that redefined women's sprint-distance capabilities.
Farah defeated Kenenisa Bekele in the 10,000m final in a thrilling kick. Bekele was the favorite and a legendary figure, making Farah's victory a monumental upset for British athletics and establishing Farah as a modern distance running icon.
Note: This entry is illustrative of early era surprises. A more prominent example is Wyomia Tyus's 100m defense (1964). Tyus repeated as champion, defeating strong field favorites. Her consistency was an upset to those expecting a new winner, cementing her status as the first woman to repeat as Olympic 100m champion.
The US team, favorites for years, finished second as Jamaica broke their own world record. This was a shock to many who expected American dominance in the relay, highlighting the shift in power toward Jamaican sprinting and the unpredictability of baton exchanges.
El Guerrouj won the 1500m in Olympic record time, defeating a field that included world champions. His victory was an upset in the sense that he was not the pre-race favorite due to his focus on the 5000m, yet he dominated both events, stunning the track world.
Gebrselassie won the 5000m in Sydney, beating world champion Richard Limo. This was a significant upset as Limo was in peak form, but Gebrselassie's experience and tactical kick in the final laps secured his second Olympic gold, adding to his legacy as the greatest distance runner of his era.

Johnson won the 200m and 400m, setting world records in both. His 200m victory was an upset as he was primarily a 400m runner, and few believed he could match pure sprinters like Frankie Fredericks. His unique biomechanics allowed him to surprise the world in both events.
Thompson-Herah won the 100m and 200m, defeating Shelly-Ann Fraser-Pryce and others. Her victory in the 100m was an upset as she was less favored than Fraser-Pryce, but she produced one of the fastest times in history, asserting herself as the new queen of sprinting.
