The Old Spanish Trail is a path that was built and used by the Spaniards centuries ago to connect the provinces of Benguet and Pangasinan.  The trail still exists today though it remains single-track and is used mainly by a few mountain climbers and locals who travel on foot.

The Old Spanish Trail 50K route begins with a steep climb to the summit of Mount Ugo, before dropping towards the picturesque Old Spanish Trail, then several ascents more to another summit before heading towards the finish line in Kayapa.

Less than 10% of the route consists of concreted paths. The rest is all dirt roads and trails. There is significant altitude gain and loss as well. The race is worth 3 UTMB® points.

From the Kayapa Municipal Hall, 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. BUNDAO is seven kilometers away from Aid Station 2 at SADDLE/DOMOLPOS, so runners are strongly recommended to fill up their bladders/bottles and eat.

Along the way, runners will pass another landmark, the ANSIPSIP WAITING SHED/ELEMENTARY SCHOOL (1935 masl, ~KM15).

From there, they are to proceed to DOMOLPOS Village (1700 masl) where locals reside, and run up a single-track trail until the “SADDLE.”

SADDLE/DOMOLPOS WAITING SHED JUNCTION (1763 masl) will serve as AID STATIONS 2 and 3 for runners will pass it twice. Spring water and trail food will be available.

Runners must proceed about three kilometers towards the LUSOD AREA/BACUYAN JUNCTION (1770 masl) via a single-track trail. At BACUYAN, they are to make a sharp left turn towards the MT. UGO SUMMIT MARKER via a two-kilometer climb.

UGO (2170 masl) is the FIRST SUMMIT. A marshal will record every runner’s name, race number and time at the peak’s marker.

From the summit, runners make their way back down to the SADDLE/DOMOLPOS WAITING SHED for two kilometers via a steep downhill dotted with switchbacks.

After passing the SADDLE/DOMOLPOS WAITING SHED again, runners will proceed to the picturesque OLD SPANISH TRAIL.  The 11-kilometer, mostly downhill trail will lead them to AID STATION 4 at the KAYAPA PROPER Market. All runners are strongly advised to eat, drink and refill here for the long grind ahead. This will be the last food station until Dayap.

This is also CUTOFF POINT 1 (8:00:00 Hours). Runners who don’t make the cut-off time will be declared as DNF (Did Not Finish) and will be ferried back to Kayapa Central School.

Qualified runners will proceed through rice paddies and a hanging bridge on their way to Barangay AMELONG LABENG, which is marked by its Barangay (village) Hall, school, a tiny place of worship, 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 5.  Only water will be available here. From this point, runners will take the concrete road of about four kilometers in distance going to the finish line in Kayapa Central School.
