Average 60km per day is a good distance to optimize your adventure and explore the most much highlights along this biking trip 10 days from Bangkok to Phuket in Thailand. The riding on this tour is nicely varied. On the gulf side, we ride on mostly flat terrain and really quiet backroads, with the exception of two short highway sections. Once we get into the hinterland, there are some more sustained hills, but these are rarely longer than 2km and are nothing that could be described as steep. Once we reach the Andaman Coast, there are minimal hills. We do share the road with some traffic through Khao Sok National Park due to the absence of backroads.
