Less than 10% off 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 SHED (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.

The 11-kilometer, mostly downhill trail will lead to AID STATION 3 at the KAYAPA PROPER West Market, the lowest point of the route.

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.

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 must make sure to check-in with the marshal.
