Iten, Kenya, proudly claims the title of "Home of Champions," and the sheer speed of its residents provides undeniable proof of that reputation. For her National Geographic series Superskilled, marathoner and traveler Eva zu Beck journeyed to this high-altitude sanctuary—perched 2,400 meters above the Rift Valley—to attempt a radical transformation of her own athletic performance. Her ambitious goal was to harness the legendary "Kenyan way" of running to shave thirty minutes off her personal best and achieve a sub-four-hour marathon. Training at 8,000 feet is described as "punishing," yet it offers a distinct physiological advantage for those who can endure the thin air and relentless hills.
Under the tutelage of Tokyo Marathon winner Rosemary Wanjiru at the Belio Running Camp, zu Beck was introduced to a lifestyle characterized by a "monastic" simplicity where every action serves the run. The daily routine is a strict cycle of two workouts, mandatory rest, and a "rocket fuel" diet prepared by the camp's kitchen. This nutrition plan features minimally processed, protein-rich staples such as ugali (maize-based carbohydrate), managu (leafy greens), and mursik, a traditional probiotic drink used to aid digestion and reduce fatigue. Complementing this is the use of sports massages to reach deep muscle tissue and promote recovery, a practice that zu Beck found provided a significant psychological boost.

When zu Beck sought the "secrets" of Kenyan speed, she discovered that there are no hidden tricks regarding form or footwear; instead, the success of these athletes stems from an unwavering, singular focus on discipline. The community lives by the mantra "Train hard, win easy," a philosophy that makes world-class speed appear effortless. The vast gulf between a hobbyist and a professional was highlighted during speed work at Kipchoge Stadium. While the elite team completed a 400-meter lap in 77 seconds, zu Beck clocked 127 seconds, illustrating that their "mastery" is the result of an entire life dedicated to the sport.
Six weeks after leaving Kenya, zu Beck applied these lessons to a grueling trail marathon characterized by muddy, rocky, and "awful" terrain. Despite training six times a week and prioritizing rest and nutrition, the technical difficulty of the course meant her sub-four-hour goal remained out of reach. She finished with a time of 4 hours and 22 minutes. Although she failed her primary challenge, she achieved the third-best time among women and finished first in her age bracket. Her journey for National Geographic served as a powerful reminder that "there are no shortcuts to greatness"; true excellence requires a level of absolute dedication that defines one's life mission.
