Guba - Sirao - Ayala Heights
I think of this route as a classic Cebu route.
It's not for the beginner cyclist and can be appropriately hard for novices, especially if you try to go as fast as you can.
It starts off with a long gradual climb from Pitos to Guba (there are a few steep portions though). Then the punishing curvy climbs up to Sirao (with a great view though). Then finally up and down to Ayala Heights where you can find many cafes on the way back down via TCH.
Here's an old video about the climb:
- 40.5 km
- 930 meters
- Plenty of stopovers at the end of the ride
- Steep road climbs
