From football fields to boxing rings, these stories have inspired generations. Here are 10 of the most remarkable underdog stories in sports history.

1. Leicester City Wins the 2015-16 Premier League

Leicester City’s Premier League triumph is arguably the greatest underdog story in modern football. Just a year prior, they narrowly avoided relegation.

Manager Claudio Ranieri and captain Wes Morgan led a squad that became the epitome of belief against all odds, inspiring fans worldwide.

2. Buster Douglas Knocks Out Mike Tyson (1990)

In the world of boxing, few upsets compare to James “Buster” Douglas defeating Mike Tyson. Tyson, undefeated and feared by all, seemed unstoppable. Douglas, considered a heavy underdog, entered the ring with little fanfare. But in a stunning display of skill, resilience, and precision, Douglas knocked Tyson out in the 10th round. This fight remains a symbol of courage, proving that preparation and heart can conquer even the most intimidating opponents.

3. USA Hockey Beats the USSR – “Miracle on Ice” (1980)

The “Miracle on Ice” became an enduring symbol of national pride and a reminder that belief can overturn the odds.

4. Greece Wins UEFA Euro 2004

Greece entered the 2004 European Championship as a 150-1 outsider, with little expectation of making an impact.

Their disciplined and fearless approach turned the tournament upside down and remains one of football’s greatest Cinderella stories.

5. Appalachian State Defeats Michigan (2007)

In college football, Appalachian State shocked the world when they defeated the 5th-ranked Michigan Wolverines. A small, unheralded team from the Football Championship Subdivision (FCS) toppled a top-tier powerhouse, marking one of the most memorable “David vs. Goliath” moments in NCAA history. The game showcased how preparation, teamwork, and belief can lead to historic upsets.

6. Rulon Gardner Defeats Alexander Karelin (2000 Olympics)

Wrestling legend Alexander Karelin had gone 13 years undefeated, winning three Olympic golds. Few thought anyone could challenge him. Enter Rulon Gardner at the Sydney Olympics.

His win remains one of the most iconic Olympic upsets.

7. Villanova’s 1985 NCAA Basketball Championship

In college basketball, Villanova University’s 1985 NCAA Championship run remains legendary. An 8th-seeded team, Villanova faced powerhouse Georgetown in the finals.

This victory symbolized the emergence of a new champion and highlighted the unpredictable magic of sports.

9. Iceland at UEFA Euro 2016

Iceland’s national football team captured hearts around the world during Euro 2016. With a population of just over 300,000, few expected them to compete with Europe’s football giants. Yet, they stunned England in the Round of 16, advancing further than most could have imagined. Iceland’s teamwork, unity, and spirit turned them into global heroes, showing that size doesn’t determine success.

10. Leicester City’s Champions League Run (2016-17)

After their Premier League miracle, Leicester City continued to defy expectations in Europe.
