About This Race
The 100K represents the ultimate Great Wall endurance challenge, demanding sustained effort across multiple historical wall sections and extended mountain traverses that test both physical resilience and mental fortitude over what typically becomes a 12-15 hour journey. This distance attracts experienced ultrarunners seeking a significant step up from standard 50-mile races, requiring careful pacing through the technical stone steps and steep ascents that become increasingly demanding as fatigue accumulates. The extended course allows for a deeper immersion into the region's remote valleys and grassland transitions, offering solitude and scenery unavailable to runners on shorter distances.
Notable Features
This race stands as the only UTMB World Series event that incorporates a UNESCO World Heritage site as its central feature. Runners traverse authentic sections of the Ming Dynasty Great Wall while gaining access to restricted historical areas typically closed to tourists. The combination of significant elevation challenges with cultural immersion creates an experience that transcends typical trail racing.
