In an extraordinary feat of endurance, strategy, and mental strength, Nigerian chess master Tunde Onakoya and American grandmaster Shawn Martinez have officially entered the Guinness World Records by completing the longest chess marathon ever—an astounding 64 hours non-stop.
The event took place at Times Square, New York City, and drew thousands of spectators over nearly three days. The duo played hundreds of blitz and rapid matches without breaking for sleep, taking only short, scheduled breaks for meals and rest, in accordance with Guinness guidelines.
The marathon wasn’t just about setting a record—it carried a powerful message. Tunde Onakoya, founder of the “Chess in Slums Africa” initiative, used the platform to raise awareness and funds for underprivileged children across Africa who use chess as a tool for education and empowerment.
“We wanted to prove that chess is not just a game—it’s a force for change,” said Onakoya after completing the 64th hour. “This record is for every child who has been told their dreams are too big.”
Shawn Martinez, a Bronx native and long-time chess coach, echoed the sentiment:
“The mind can go further than the body. This wasn’t just about stamina, it was about belief—and the community that stood behind us.”
The duo played more than 400 games during the marathon, with both players alternating between intense focus and lighthearted banter to keep spirits high. Volunteers, fellow chess players, and fans gathered to support the effort, while donations poured in from around the world.
Guinness World Records adjudicator Elena Brooks, who oversaw the attempt, confirmed the record was broken on the evening of April 21.
“It was an incredible demonstration of resilience, sportsmanship, and passion for chess,” she said.
With this historic achievement, Onakoya and Martinez not only entered the record books but also spotlighted the global power of chess to unite, inspire, and uplift. The duo has hinted that this is just the beginning of more collaborative, purpose-driven events to come.
