For people really interested in cycling here in the Philippines, (Manila, Cebu, Davao, Davao, Tagaytay, Subic Base etc) try hooking up with REAL cycling buddies at https://www.pinoyroadies.org/forums/ They will be more than happy to accompany you on your cycling experience here. All for free and good camaraderie!

If you would like to explore going "off the beaten path" (read: Mountain or trail biking), you could also post your itinerary on our forum https://www.pinoymtbiker.org/forum/. Just introduce yourself and what you intend to do. I am sure a lot of groups and bikers would either join you for certain legs of your trip or might join you for the whole trip. A team of two mountain bikers just finished a trip from Manila to as far as Davao just the other day. I am sure they can give you fresh and updated tips on what to do and what to avoid in such a trip. Ride safe!
