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.


1. Please proceed to the registration table for Body marking and Race band claiming

2. Secure the Race Bands around your wrist throughout the race. We will implement Race Bands as penalty system where racers must complete each Penalty obstacle to avoid getting his/her band/s cut.

  • 50km: 5 bands each
  • 25km: 5 Bands
  • 12km –no bands, obstacles are optional but “Highly Recommended” ;)


Please check your start time and stick to your time slot. Athletes arriving late after their start time will still be allowed to race but their time will start running from their assigned start time. Racers will start by groups of three; with 1 Minute interval between groups.

Athletes are not allowed to use the obstacles and the course for warm up.

Athletes who have finished their run will be required to leave the site 30 minutes after they finished the race.

  • 50km: 5am
  • 25km: 6am
  • 12km: 7am
  • 12km Para: 8am


  • 50km: 9 hrs
  • 25km: 4 hrs
  • 12km: 2.5 hrs


Since POSF Ultra OCR is a qualifying race for the National Team selection, and to conform to the World Obstacle standards, we will implement the 1 try rule for the 50km athletes and 2 tries/attempts for 15km/25km participants and unlimited tries for 6km racers.

Failure to do a penalty obstacle will mean a penalty for the racer. One band will be cut from the racer’s wrist every time he/she fail a penalty obstacle and is equivalent to “15 Burpees”. Losing all the wrist bands will mean the racer can still finish the race but will be unranked from the overall results.

There will be a dedicated area near the end of the race course where the penalties will be performed. Failure to perform the penalty exercise will mean disqualification from the race.


Our race staff will write your race numbers on both arms with permanent markers, avoid

putting on sun block before body marking
