A record line-up of 3,200 athletes from around the world took part in The North Face 100 Thailand 2017 on February 4 in Pak Chong, Nakhon Ratchasima.
Launched in 2012, when trail running was a little known sport in the country, the event has since grown to become the largest of its kind and is part of the annual Asia Pacific Series.
Tough conditions, with temperatures exceeding 36 degrees centigrade during the day, made for a challenging event for all runners across the five distances – 15km, 25km, 50km, 75km and 100km.
