Rudisha confirmed the sad news on Friday, December 19, 2025, via a statement shared on X, describing the loss as a deeply difficult moment for him and his family.

“Hello, I just wanted to share some very sad news. My mother, Naomi Matasi, AKA Mama Poroko, passed away this morning, and it’s been a tough time for me. I deeply appreciate all your support and understanding during this period,” Rudisha wrote.

Naomi Matasi’s death comes at a time when her son continues to be celebrated as one of the greatest 800-meter runners in history. 

David Rudisha captured global attention with his remarkable performances, including back-to-back Olympic gold medals at the 2012 London and 2016 Rio Games. At London 2012, he set the world record for the 800m with an unprecedented time of 1:40.91—a record that still stands today.

Rudisha’s illustrious career also includes two World Championship titles (2011 and 2015), two Diamond League victories (2010 and 2011), and the distinction of being the only athlete to have run under 1:41 in the 800m. 

Beyond the 800m, he holds the world best for the 500m and the African best in the 600m. Recognized for his consistency and dominance on the track, Rudisha has also been named the IAAF World Athlete of the Year in 2010 and earned three consecutive Track and Field News Athlete of the Year awards.

While Naomi Matasi largely lived a private life away from the public eye, her influence on her son’s journey has been evident. 

She is remembered as a supportive figure whose guidance and encouragement helped shape Rudisha into the disciplined and determined athlete admired worldwide. The moniker “Mama Poroko” reflects her nurturing role within her family and community.

David Rudisha, now retired from professional athletics, has also ventured into public service, announcing in May 2022 his candidacy for election in Kenya’s Kilgoris Constituency as an independent candidate. 

Beyond politics, he has continued to serve as a role model for young athletes, emphasizing discipline, perseverance, and community responsibility. In March 2024, he represented World Athletics as an ambassador during the 2024 World Athletics Indoor Championships in Glasgow, Scotland.

The passing of Naomi Matasi is a personal tragedy for Rudisha, his family, and the wider athletics community that has followed his career closely. Tributes have poured in from fans, fellow athletes, and Kenyans at large, celebrating her role in raising one of the nation’s greatest sporting icons.

As the family navigates this period of grief, supporters are called upon to respect their privacy while extending condolences and moral support to David Rudisha. 

While the arrangements for her funeral have not been detailed, it is expected that the family and close friends will honor her life in a dignified manner, reflecting the respect she garnered from those around her.
