Joyce "Tata" Nduku, affectionately known as the Granny Marathoner, is a Kenyan marathon enthusiast runner who has defied age barriers in the sport. She began her running journey at the age of 50, motivated by a desire to improve her health and prevent lifestyle diseases. At 56, she completed the Two Oceans ultra-marathon in South Africa, running 56 km as a birthday feat. Since then, Nduku has completed several World Marathon Majors, including the Chicago Marathon (2008), the New York Marathon (2019), and the Boston Marathon (2021). She hopes to eventually run in all six major marathons, with her sights set on Berlin, London, and Tokyo.
