Yuki Kawauchi Proves His Endurance with New Marathon Success in 2025

Yuki Kawauchi, known worldwide as the “Citizen Runner,” continues to defy expectations in the marathon world. From his historic 2018 Boston Marathon victory to his latest triumphs in 2025, Kawauchi remains one of the most consistent and determined long-distance runners in the sport. Now a full-time professional, he has overcome setbacks and continues to post impressive results on the global stage.

The 2018 Boston Marathon Victory

Kawauchi cemented his place in marathon history on April 16, 2018, when he won the Boston Marathon in one of the most challenging weather conditions the race had ever seen. With heavy rain, powerful headwinds, and freezing temperatures around 40°F (4°C), many elite runners struggled—but not Kawauchi. His relentless surges and fearless strategy allowed him to overtake defending champion Geoffrey Kirui in the final miles, crossing the finish line in 2:15:58. He became the first Japanese man to win the race since Toshihiko Seko in 1987.

Transition to Professional Running

Despite his international success, Kawauchi spent years balancing his training with a full-time job as a government clerk. In 2019, he made the long-awaited decision to turn professional, allowing him to focus entirely on training and racing. The transition led to an improvement in his performances, including a personal best marathon time of 2:07:27 at the 2021 Lake Biwa Marathon.

Battling Through 2024

The road to success is never without obstacles. In 2024, Kawauchi endured an inconsistent season, marked by injuries and slower race times. However, he continued to compete with determination, finishing several marathons despite the setbacks:

• Ibusuki Nanohana Marathon (January 2024): 1st place, 2:21:13

• Paris Marathon (April 2024): 75th place, 2:31:03

• Gold Coast Marathon (July 2024): 156th place, 2:42:26

• Hofu Yomiuri Marathon (December 2024): 38th place, 2:33:01

• Mie Matsusaka Marathon (December 2024): 6th place, 2:22:02

Despite these struggles, Kawauchi never lost sight of his goal—to return stronger in 2025.

A Strong Comeback in 2025

This year, Kawauchi has proven once again why he is one of the most enduring marathoners in the world. His persistence paid off with a strong performance early in 2025:

• Tokyo Marathon (March 2025): 15th place, 2:10:45

His victory at the Tohoku Miyagi Revive Marathon was a defining moment, signaling that Kawauchi is back in top form.

Training and Personal Life

Now a professional, Kawauchi has adapted his training regimen to include higher mileage and more structured workouts. He still follows an old-school approach, frequently training alone and racing more often than most elite marathoners. His high-volume racing strategy continues to set him apart, proving that consistency and experience can be just as valuable as raw speed.

In his personal life, Kawauchi married fellow runner Yuko Mizuguchi in 2019. The couple shares a passion for marathon running, supporting each other’s athletic careers. Their shared dedication to the sport has made them one of Japan’s most inspiring running duos.

A Lasting Legacy

Yuki Kawauchi has defied conventional wisdom in long-distance running, proving that elite performances don’t require sponsorships, high-tech training camps, or corporate teams. His dedication, work ethic, and ability to push through challenges continue to inspire runners of all levels.

With his recent 2025 victory and continued improvement, Kawauchi remains a formidable competitor in the global marathon scene. Whether battling extreme weather or personal setbacks, his resilience and love for the sport continue to make him a legend in the running community.
