This is an out-and-back course on a footpath connecting Clark (formerly Clark Air Base of the American servicemen and during pre-WWII, it was called Fort Stotsenburg) to the scenic Miyamit Falls in Porac, Pampanga.

The 5th edition of CM50 will be officially part of the ASIA TRAIL MASTER SERIES.

The route

An old trail used primarily by Aetas to travel from their ancestral land, Clark and other neighboring areas. The route will take runners from the Tennis Court area of Clark Parade Ground (Start/Finish line) at Clark Freeport Zone (formerly Clark Air Base), Gate 14, Sacobia River, Puning Spa, Sitio Target, up the dirt road covering the sugar cane plantation, Sitio Ebus (Aeta community), down to the expansive Pasig-Potrero River (river crossing), parallel dirt road along SCTEX, Crow Creek (Sapang Uwak), passing through the Aeta community, then up to Miyamit Falls and the peak (about 3kms to caldera of Mt. Pinatubo) and back to Clark.

CM50 is a member of the International Trail Running Association (ITRA) and carries two (2) qualifying points of UTMB (NORTH FACE® ULTRA-TRAIL DU MONT-BLANC®).

NOTE: This is a physically demanding race. Runners are strongly advised to train properly for it. 50 miles is still called the DNF Challenge.

Course condition: Gravel road, fire trails, dirt road, river and lahar crossings, single tracks and partly asphalt/concrete road.

Weather: For the most part, the period from November to February in the Philippines is the coldest time of the year. During the past 3 editions of CM50, weather was relatively cool and it can get really chilly up in the mountains with the occassional drizzle and hot dry weather around noontime.

Did it this year (2015) It was one tough journey! I mean, it has everything from single tracks, steep climbs, fast downhills and those nasty river crossings! Not your everyday river, mind you. These are shallow sandy rivers, so you're pretty much digging through 10 inches of sand (which is actually a thick layer volcanic ashes, called lahar) while crossing them. Oh and the Miyamit falls is so beautiful, and that is just the bonus because the view is super amazing - its a sin not to take photos after every major turn. And the race... well-organized. I'd give it an 8.5 on a scale of 1-10.

Venue: Clark Freeport Zone to Porac, Pampanga, Philippines –
Date: November 21 - 22, 2015


Manolito Divina and Maria Josephine “Majo” Liao each walked away with their second consecutive win at t the 2015 Clark-Miyamit Falls 50 Mile Race. Manolito has set a new course record of 9:22 hours by beating the previous one that he established in 2014. Majo’s finish marked her fourth CM50 and she also hit a new personal record of 12:37, faster by almost two hours.

On the shorter distance category, American elite runner Meredith Edwards has dominated the distance and finished ahead of competitors, including his male counterparts. Al Tellias took home the male championship finishing fifteen minutes after Meredith.

“This edition has been the most festive for the past five years. The race has remained intimate and maintained an underground vibe. Attributable to the growth of trail running, spectators and volunteers came in flocks. Family members and friends who have witnessed the months of rigid training of the competitors came to celebrate as well. We also have the biggest number of foreign registrants from different countries. It gave me goose bumps welcoming the runners as they crossed the finish line from the top finishers to the last ones. Some did not make it within the cut-off or has pulled out during the race but we know they will come back stronger.”, Atty Jon Lacanlale, Race Director (RD) shared..

“This year, we also celebrate the 5th consecutive finish by Jael Wenceslao towho received the BaddestBaldest Ass Award. Jael has witnessed how CM50 has grown from its initial staging until this year. We have seen runners come back each year, stronger and better.”,” the RD added

Runners were welcomed by the organizing team and The Villages (Global Clark Assets) on Saturday, November 21 for their Race Kit Claiming.Each participant received their #CM50 Headware and Berocca Performance tubes.

At 2pm, everyone was all ears to the RD for the race briefing. A Veterans Talk followed with guestswith guests: Champions Majo Liao and Manolito Divina, International Trail Runners who are seasoned CM50 top finishers also, Alex Yap and Simon Sandoval, and Thailand-based Filipino Runner Jag Llanante who is the sole finisher for HK4TUC in 2015. These seasoned trail runners shared their CM50 tips and gamely answered questions from the crowd from racing tips to fun love questions. The event was made more fun with raffles from Simple Hydration, Headware, Ahon, ROX and Altra Shoes.

Runners started to check-in at 10:30 pm. Mandatory gears were checked and bibs were scanned by 98Labs representatives. With the official race song (Earth – Believe) playing on the background, one could feel the nervousness and excitement amongst everyone. “I want to be bad ass this year.”,” said Carlo Gonzales who is coming for a revenge from last year’s DNF.

At 1 am, 193 runners went off to traverse their way to Miyamit. In the dark, they took the route passing through Sacobia River, some short steep ascents and descents through hills, and flat lahar pathways, Aeta Villages and sugarcane plantations which end with another crossing through ,Pasig-Potrero River. The steep ascents towards the peak started at Sapang Uwak, the third aid station.
Runners started to arrive here at 3:08am. With 3120 meters of elevation gain, even the lead runners had to resort to fast hiking. The scorching heat of the sun challenged the runners on their way back and everyone was not spared.
Sun started to set after the 60K cut-off was declared and 8% did not make it within the time barrier.

With less than an hour remaining until the cut-off at 7pm, everyone started lining up the track oval to the finish line waiting and cheering for the remaining 50 mile runners. Almost 40% of participants have yet to cross the finish line at the 17th hour. The crowd grew ecstatic every time a headlamp appeared showing signs that another CM50 Bad Ass would make it to the cut-off.

With five minutes left to before the race would be officially over, Runner Richard Lim could be seen around 400 meters away to the finish line. Out of concern, RD Jon ran to him and paced and pushed him to run faster and barely making it to the finish line with less than 2 minutes before the time barrier of 18 hours. The crowd was hysterical.“I am honoured and thankful to be paced by the RD. Mabuhay kayong lahat! (Cheers.), tThanks to the rest of the CM50 crew for an extremely organized race. It was very tough, heart pumping and lung busting.”, Richard Lim shared.

During the Veterans Talk, Manolito said that his goal was to beat his course record last year. “This pushed me to go for the win.”, Manolito said. With equally strong foreign contingent and a deep field of local trail runners, the race had drummed up excitement among the spectators.

Manolito together with Norway’s Jan Nielsen had been leading the race together. About fifteen runners trailing in 15 minutes behind them. By the time they made a turnaround at the peak, Manolito had gained an 8 minute lead and the runners ranking has changed. Koi Grey stayed behind the two leaders with the lead cut down on Nielsen to 2 minutes as they reached Aid Station 3. With 23 minutes kilometers to ago, Manolito maintained his lead on Nielsen while Grey lost his 3rd position due to a wrong turn. James Tellias who had been on the fourth position finished in the top three instead.

The women’s field was equally competitive. Majo Liao said she has prepared for the race as build up to a big race three weeks after CM50 but was sidelined by an injury two weeks prior. “I was trying to dig deep as we go through the steep ascents to the peak but I was losing it. The shooting stars kept me entertained from the lingering back pain. Until Miyamit sunrise with Mount Arayat and the mountain ranges as backdrop showed up. It energized me and there was no turning back, I enjoyed the run heading back and was inspired by the new faces I have met along the route.”, she shared.

The race started with the top ten female trailing behind each other within few minutes distance at the first quarter of the race. Mid-way at the peak turnaround, Silamie Apolistar arrived ahead of the United Kingdom’s Joanne Plumbley and Majo who were four minutes behind. Majo took the lead going down the peak and maintained her lead.
