British explorer becomes first person to travel the length of an uncharted Amazon river

A leading British explorer has become the first person ever to travel the length of an uncharted Amazon river. Adventurous Ash Dykes, 33, battled sickness and hallucinations to finish his epic 37-day trip by reaching the mouth of the Coppename River in Suriname, South America. The extreme athlete and his teammates Jacob Hudson, Dick Lock and Matt Wallace, kayaked continuously for the final three days and nights to complete the mission. And after suffering from sleep deprivation, infections and malnutrition, they saw strange visions before finally getting to the Atlantic Ocean.
