David Lekuta Rudisha (born 17 December 1988) is a retired Kenyan middle-distance runner who is widely regarded as one of the greatest 800-meter runners in the history of athletics. He is a two-time Olympic gold medalist (2012, 2016) and a two-time World Champion (2011, 2015). Rudisha holds the current world record in the 800-meter event, an iconic mark of 1:40.91, which he set during a historic performance at the 2012 London Olympics. He remains the first and only person to have run the 800-meter distance in under 1 minute and 41 seconds. Born in Kilgoris, Narok County, Kenya, Rudisha belongs to the Maasai ethnic group. His family has a deep-rooted history in athletics; his father, Daniel Rudisha, was a prominent runner who won a silver medal in the 4×400-meter relay at the 1968 Mexico City Olympics. His mother, Naomi, was also a competitive 400-meter hurdler. Growing up, Rudisha was inspired by his father’s achievements, often motivated by the silver medal he saw in his home. Rudisha attended St. Francis Kimuron High School in Iten, Elgeyo-Marakwet County, a region famous for producing world-class distance runners. It was there that his potential was identified by the renowned Irish coach Brother Colm O'Connell. Although Rudisha initially trained as a 400-meter sprinter, O'Connell encouraged him to transition to the 800-meter distance, a strategic move that defined his career. In 2006, at the age of 17, Rudisha demonstrated his burgeoning talent by winning the gold medal at the World Junior Championships in Beijing. His professional career ascended rapidly thereafter. In 2010, Rudisha gained international prominence by breaking the 13-year-old world record held by Wilson Kipketer. He achieved this feat multiple times that season, culminating in a world record of 1:41.01 in Rieti, Italy. That same year, he became the youngest athlete to receive the IAAF World Athlete of the Year award at age 21. His crowning achievement arrived at the 2012 London Olympics, where he dominated the 800-meter final, leading from the start and setting his standing world record of 1:40.91 in a race described by many pundits as the greatest 800-meter race ever run. Four years later, he defended his Olympic title at the 2016 Rio Games, becoming the first man in 50 years to win back-to-back Olympic 800-meter gold medals. Beyond his speed, Rudisha was celebrated for his fluid, graceful running style and his composure under pressure. Throughout his career, he faced several injury setbacks, including issues with his knee and back, yet he remained a formidable force until his retirement. Off the track, Rudisha is known for his humility and commitment to his family; he is married to Lizzy Naanyu, with whom he has children. In the years following his competitive career, he has remained involved in the athletics community, acting as an ambassador for major championships and inspiring a new generation of runners. His legacy is defined by his unparalleled dominance in the 800-meter event, having set the three fastest times in history during his peak years.
