Competitor bio:

Ning Chen is a runner who defies categorization: a senior by age, a junior by pace, and an enthusiast by the sheer number of races and total distance he covers each year. His running journey began later in life—at the age of 45—when he set a bold goal to transform himself at a pivotal stage. Once a self-proclaimed sports despiser who could not complete even a single kilometer without struggle, Ning Chen redefined himself as a passionate athlete (by his own standards) through perseverance and dedication. A proud Abbott World Marathon Majors Six Star Finisher, he is completing his 100th full marathon during his current 777 Challenge. Ning Chen feels deeply grateful for discovering running when he most needed a new source of energy, passion, and discipline. Beyond physical strength, the sport has enriched him mentally, cultivating patience, endurance, and resilience—qualities essential for thriving in today’s fast- changing world.
