Four Lakes 100K is worth 5 UTMB® points. Less than 10% of​f the route consists of concrete roads. The rest is all dirt roads, switchbacks, steep ascents and descents on natural surface.​ ​FL100 runners will pass the Old Spanish Trail and conquer ​a number of summits and four lakes. They will share the same route with OST50 runners for the first half of the race.

From Kayapa ​​Central School, runners will start heading towards the trailhead in Talecabcab and ascend eight kilometers through a mix of dirt roads and intermittent stretches of concrete tire paths towards Indupit.​ ​The climb ends at the INDUPIT JUNCTION where the ANSIPSIP foot trail starts (1866 masl).

Runners will proceed around 2km to the next landmark, BUNDAO (1835 masl, ~KM10) where AID STATION 1 will be located. On their way, runners will turn right upon reaching ​ANSIPSIP WAITING SHE​D (1970 masl, ~KM11​) and run towards Barangay ANSIPSIP, (~Km 15). From there, runners will go to Bacuyan(1770 masl), and start the ​more than ​1-kilometer ascent to the summit of Mount Ugo​(2150 masl), the highest point of the course​. All runners must make sure to check in with the race marshal at the peak, who in turn, will record every runner’s name and​ race number​.

​After summitting, runners will return to Bacuyan Junction, and make a sharp right turn towards the SADDLE/DOMOLPOS WAITING SHED(AS 2), where spring water and trail food will be available. After passing the SADDLE/DOMOLPOS WAITING SHED, they will proceed to the picturesque OLD SPANISH TRAIL. The 11-kilometer, mostly down​​hill trail will lead to AID STATION ​3​ at the KAYAPA PROPER East Market​, the lowest point of the route.​

All runners are STRONGLY advised to eat, drink and refill here for the long grind ahead. This will be the last food station until​ ​Castillo Village AS.​ Kayapa Proper East Market is also CUTOFF POINT 1 (8:00:00 Hours). Runners who do not make the cut-off time will be disqualified and prevented from resuming the race.

From Kayapa Proper Market, runners will pass rice paddies and a hanging bridge on their way to Barangay AMELONG LABENG, which is marked by its barangay (village) hall, school, worship place and a basketball court.
​ ​
The next landmark to the SECOND SUMMIT will be a cellular phone site tower. Runners will then exit at the Nueva Vizcaya-Benguet Road, turn left and proceed uphill on a concrete road to the entrance of CASTILLO VILLAGE which is marked by a huge welcome sign, a waiting shed and a World War II Memorial. The shed will be AID STATION ​4 and CUTOFF POINT 2 (~52 kilometers, 14:00:00 Hours)​​.​ Drop bags for participants may be accessed here.​ ​Runners who do not make the cut-off time will be disqualified and prevented from resuming the race. A vehicle will be provided to ferry disqualified runners to the finish line.

From the village trailhead, runners will proceed two kilometers to BUACA LAKE (Lake 1). A few hundred meters away will be Lake 2 (if not dry). This is also the THIRD SUMMIT. Runners will pass vegetable ​gardens​,​ descend to a “saddle” area​ (Giwang)​, ​​turn right ​downhill towards Talmoy, and eventually ​ascend going to ​Banao AS​(Aid Station 5)​, where names and numbers will be recorded. All runners mus​t ​make sure to check-in with the marshal.

​From Banao, ​runners will make their way to DAYAP PRIMARY SCHOOL​ via Ambasa, and Nayao Lakes 1 and 2(Lakes 3 and 4). Dayap is CUT-OFF POINT 3 (24:00:00 hours), and the last AID STATION (#​6​).​ ​Qualified runners will proceed for about three kilometers towards the PANGAWAN /BOUNDARY trailhead, enter the trail that leads to ​the mossy forest and ​INDUPIT Village Junction​,​ and from this point, ​turn left and​ take the TALECABCAB TRAIL ​, and run downhill ​towards the finish line in Kayapa Central School.
