Since these wont do much justice, in general the terrain is like Mordor, without the darkness.
Always dry and dusty, rock with sharp edges everywhere. Downhills are short and not too steep, plent of opportunity to pedal, so when back to Europe I literally die on the steeps. Different challenges for sure, the heat and humidity can be quite a killer.
Are there mountains there where you can get away from the heat? Looks like an really cool place to ride, but I'm a delicate flower and wilt in the heat.
