Amazean Jungle Thailand by UTMB sends trail runners from Betong's Mongkollit Tunnel into the steep, wet forests of Thailand's far south. Six distances, from a four-kilometre night run to a 116-kilometre mountain race, make the weekend accessible to newcomers while the long courses demand serious tropical-ultra preparation.
Before dawn at Mongkollit Tunnel, Betong feels less like a resort town than a threshold.
The race uses Betong's borderland terrain rather than presenting a generic road event with jungle branding
Every course starts and finishes at the historic tunnel, then longer races climb through humid forest, plantations and mist-prone ridges near the Malaysian frontier
The 116-kilometre Betong 100M accumulates 5,570 metres of ascent
even the 55-kilometre Jungle 50K gains 2,200 metres
UTMB World Series organization gives that demanding local landscape international trail-running structure and qualification value
