The event is a PHILTRA-recognized event in partnership with the Pilipinas Obstacle Sports Federation, a National Sports Association recognized by the Philippine Sports Commision and the Philippine Olympic Committee.


This event is a PHILTRA-recognized event. The event organizer is one with Philtra to facilitate the setting of Philtra Trail Running Standards in events across the Philippines.


The event will be held at the The La Mesa Watershed Reservation, a protected area that preserves the only major watershed in Metro Manila. It is the primary source of drinking water for those living there, and it also contains the last remaining rainforest of its size in this area. That's why back in 1999 ABS-CBN Lingkod Kapamilya Foundation, through Bantay Kalisan started "Save the La Mesa Wastershed Project". Their aim was to reforest and protect the watershed, and also to convert it into the environmental capital of Metro Manila.

The La Mesa Nature Reserve is completely reforested and has hiking and mountain bike trails for anyone to enjoy. Run in an almost untouched forest in the middle of the city with big trees overgrown with vines,dense bushes and the beautiful and calming view of the water reservoir.
