Pong Yaeng Trail started in December 2015 with 69 runners in the PYT66 and slightly more at 79 runners for the RTC30. The 5th iteration of Pong Yaeng Trail in 2019 welcomed more than 2,500 runners in 7 races, the route went through 3 National Parks, and the longest distance was the PYT166.
A northward climb up to Pong Yaeng follow by hooking west before heading southward to Nin Prapa Temple, this route is no less challenging than the longer ones.
