About This Race
The 29K distance offers 900 meters of elevation gain with a 6-hour cutoff, positioning it as the ideal step up for runners ready to progress beyond the introductory 17K while avoiding the multi-day training commitment required for the longer UTMB World Series distances. This option allows runners to experience the full character of the jungle terrain and international border crossing without the ultra-endurance demands, making it particularly suited for those seeking their first taste of technical trail running in Southeast Asia's humid, challenging environment. The generous cutoff provides ample time to navigate the jungle sections safely while still maintaining the competitive edge that defines the UTMB World Series experience.
