Kenya’s John Korir Follows Brother’s Advice to Secure Boston Marathon Victory

John Korir, the 28-year-old Kenyan runner, achieved a historic victory at the 2025 Boston Marathon, capturing the men’s title in a blistering 2 hours, 4 minutes, and 45 seconds — the second-fastest time in the race’s storied history. This remarkable win not only secured Korir’s place in the marathon’s rich legacy but also marked a milestone for his family, as he became the first sibling to win Boston alongside his older brother, Wesley Korir, who claimed the title in 2012.

As Korir prepared for his third Boston Marathon, he sought guidance from someone who knew the race well — his brother, Wesley. At 14 years his senior, Wesley had already conquered the world’s oldest marathon, and his advice proved invaluable to John.

“He told me to expect a tough race and to believe in myself,” John recalled. “So, I believed in myself and followed his advice.”

That belief led John to a historic victory, with his brother cheering him on every step of the way. As John neared the finish line, Wesley couldn’t contain his excitement, jumping up and down as his younger brother closed in on the win.

The race was far from easy. In the early stages, John stumbled and nearly lost his race bib after being tripped from behind. But the Kenyan’s quick reflexes allowed him to recover and sprint past the finish line, where he was greeted with an emotional embrace from Wesley.

Despite some fierce competition — including Alphonce Felix Simbu of Tanzania and Cybrian Kotut of Kenya, who finished close behind — John’s focus and tactical move at Mile 20 proved to be the game-changer. By the time he reached the iconic Citgo sign with just a mile left, his lead had grown to nearly a minute.

“I made my move around 20 miles, near Heartbreak Hill, and it worked well,” John said.

The race was competitive, with Conner Mantz of Provo, Utah, putting up a strong fight. Mantz was in contention for a top spot but faded in the final stretch, finishing fourth after a fierce battle with Simbu and Kotut.

Sisay Lemma, last year’s champion from Ethiopia, initially led the pack but couldn’t maintain his pace and was forced to drop out around Mile 17 due to an apparent injury.

Despite the challenges, Korir’s victory was secured after a final sprint down Boylston Street, where his family’s support and his disciplined strategy propelled him to the top.

With his $150,000 prize, John echoed his brother’s philanthropic efforts. Wesley, having used his own prize money to build a hospital in Kenya, inspired John to pledge part of his winnings to the Transcend Talent Academy, an educational initiative that helps aspiring runners from disadvantaged backgrounds.

Reflecting on his victory, John shared a heartfelt moment with Wesley after crossing the finish line.

“Afterwards, he told me he was proud,” John said. “Now we’re two brothers to win Boston.”

The 2025 Boston Marathon will be remembered not only for its fast times and fierce competition but also for the Korir brothers’ historic achievement, marking a powerful family legacy in marathon history.
