As part of my training, I'm going to do tomorrow the Novaliches to Antipolo to Mt. Maarat to Novaliches loop. This is about 68 kilometers.
My intended route:
Novaliches - Masinag - up to Antipolo via Sumulong Highway - down to Cogeo via Olalia Road - Cabading - up to Mt. Maarat - Timberland - down to C6 - Novaliches.The distance from Masinag up to Olalia Road via Sumulong Highway is about 7 kilometers; while from Cabading up to Pintong Bocaue 4 kilometers.
If there's extra time, I'd side trip to any of the trails in Mt. Maarat.
