All distances are out-and-back and will START/FINISH at the Filinvest Mimosa+ Leisure City at Clark Freeport Zone. The course condition may vary depending on the weather but the terrain consists of gravel roads, fire trails, dirt road, river and lahar crossings, single tracks and concrete road.
You will be running towards Gate 14. A three-kilometer road section where it will lead you to the foot path towards Sacobia River. Once you head in to SACOBIA RIVER, you are advised to follow the ORANGE REFLECTIVE markers and the red light blinkers during night time but if one is having a hard time looking for the markers, stay on the left side. Your shoes and feet will certainly get wet here. The entrance to the AS1 is on the left side marked by a red blinker. There is a partially hidden CONCRETE steep stair on your right. Take it.
AS 1: SITIO TARGET
This place is around 10.5K from the Start and the turning point of the 21K runners. From this AS, you will be heading to a dirt road covering the sugar cane plantation. Please look for markers on the leaves, tree trunks, on the ground, stones, rocks, etc. for proper heading. Afterwards, you will be crossing the Pasig-Protrero Riverbed, an almost dry riverbed around 2KM wide where you will be heading to AS 2 across Sitio Ebus.
AS 2: PASIG-POTRERO
From Pasig-Potrero, there will be an entrance to Alviera. You will then see one of the two tunnels. After passing through this first tunnel (going to Sapang Uwak) make sure you make a right turn. Going straight will bring you to SCTEX which is a wrong way. The second tunnel you will be passing through is 1KM away or so which goes (a descending dirt road) to the left heading to Sapang Uwak. NOTE: Alviera or Sandbox is not part CM50 course.
There will be a STEEL BRIDGE which you will see. Follow and cross the bridge about 1.5K after the 2nd tunnel. Make sure to turn left after crossing the bridge. There should be a stone bridge a few meters after making the left turn. Go up straight to Sapang Uwak as there is a fork. Do not take the left DIRT road. Just go straight. Follow the main road. You will know when you are in Sapang Uwak because there is the Sapang Uwak Elementary School on your left and a small street basketball court on your right.
AS 3: SAPANG UWAK
The AS is roughly 22K from the start and is located at the Tourism Office. From here is mostly uphills and downhills of paved dirt road. Here you will experience summer in November as the field of sunflowers await you during sunrise.
AS 4: MIYAMIT JUNCTION
For 50-mile runners, you will be passing through this aid station thrice (3) and for 60K runners, twice (2). All 50-mile runners must go up to the Peak before going to the Falls. There is no aid station reaching the peak which is a total of 20K. Runners thus have to carry additional fuel and fluid. Two liters is advised and the terrain is hilly, remote and almost inaccessible but very scenic.
