In the distaff side, Majo Liao (back to back champion) is toeing the line for a possible third victory.  Strong contender is Baguio runner Sandi Menchi who recently won the Mt Kinabalu International Climbathon.  Daphne Codilla (4th ), Mary Gold dela Cruz (5th)  and Rizalyn Damaso (7th) are some of the top ten female runners who are expected to show up this year.  Cherry Chung from Hong Kong who won third at Vietnam 70K is also in the start list.

This year will also mark the 5th consecutive race for six runners: George Javier, Simon Miranda, Aldean Lim, Mark Brian Grey, CJ Paran and Majo Liao. Their 2016 finish will include them to the Baddest Ass Runners list joining sole title holder, Jael Wenceslao. Read our brief feature about our five contenders.

When asked why they have joined the race for five consecutive years, 2013 Champion Aldean Lim said, “It is a race where you will see the Philippine Trail Running Community gather together.”  He looks forward to seeing a tough competition with the increasing number of international runners.  Simon Miranda said one should include this in his bucket list if you are a trail runner.

Liao, Paran and Javier all shared that the terrain varies and it is very challenging.  The weather can become chilly at night and scorching hot as you come back.  It is a race that trail runners really prepare for.


The CM50 race offers a rare chance to visit the iconic Miyamit Falls by traversing the route is mostly fire trails, dirt road and single track trails.   Runners shall go through lahar, the expansive Pasig Potrero and sacobia River, aeta villages, dirt roads and a hilly route with a picturesque view of Pampanga, Mount Arayat and mountain ranges.  The 50mile runners will go through a long ascent of single track trails, an old trails used by the Aetas, towards the “peak” (3kms near the caldera of Mt. Pinatubo) .The iconic Miyamit Falls is the last turnaround point for both distances before heading back to the finish line. 

Notable also is that majority of the runners are repeaters. "Dubbed as a tough race, we can only say that CM50 is a time to go back to nature, enjoy the beauty the course offers and surpass the challenges the route shall serve.", Atty. Jon Lacanlale, Founder and Race Director. Read our RD's race report from the time CM50 was founded
