Almost 3,000 trail runners from 50 countries are expected to show up this 3 February for The North Face 100 Thailand 2018. While the majority of runners will be competing in the 15km, 25km, 50km and 75km distances, it is the 100km ultra-distance that many of the region's top elite runners will be going up against each other in.

The North Face 100® Thailand is part of the The North Face 100® Asia Pacific Series and has become a must do for many of the region's top runners, especially because it is also a Qualifying Race for the Ultra-Trail du Mont-Blanc® (UTMB)–the Everest of trail running.

A line-up of competitors in the 100km distance includes Thailand’s Jantaraboon Kiangchaipaiphana - who won second place in 2017, Sanya Khanchai - a two-time winner in 2013 and 2015, and Phairat Varasin - who finished the Hong Kong 100 Ultra Trail® Race last weekend at 31^st place.

Hong Kong policewoman Wyan Chow who won the Hong Kong 100 Ultra Trail® Race (100km) in 2015 will be competing in her first ever North Face 100 Thailand. She will be racing against Thai Phitchanon Mahachat - last year’s winner who is looking forward to defending her title, as well as Carole Fuchs - who is stepping up from her 50km victory last year to race her first 100km at this year’s event.

The competition is expected to be tough as the undulating hills and trails of Pak Chong District will challenge trail runners to push their ultimate limits.

Thailand's Ultimate Trail Running Challenge, The North Face 100® Thailand attracts runners from all over the world each year and has put Thailand on the map as a top trail-running destination in Asia.
