China Ultra 100 - Puer will take place in Pu’er, Yunnan Province on May 28 and 29, 2016. There are two categories - 50K and 100K, both of which lead competitors through the vast sub-tropical forest in Western China to the borders with Vietnam, Laos and Myanmar, where Chinese minorities and Han Chinese have lived together since ancient times. The course will take competitors through forests, tea fields, coffee plantations and villages - competitors will experience many different types of terrain, but mostly trails or dirt tracks. The total elevation gain is 4832M for the 100K and 2834M for the 50K. Pu'er in Yunnan is one of the most beautiful regions in China and the race goes through it at the end of dry season.
