British explorer and extreme athlete Ash Dykes has today announced details of his latest expedition – and it includes attempts at three world records, including one world-first and two for speed. They’ll add to the three world-firsts that he already holds.

This time, Ash is heading to one of the most unexplored regions and greenest countries of the world, deep in the Amazon rainforest of South America

Uncharted: Suriname is Ash’s fourth major expedition and it’s set to be his most gruelling yet. For some 50 days, he’ll travel the most unexplored tracts of rainforest left on Earth - scaling the country’s two highest peaks and kayaking from the Coppename River’s source to the sea. But he must find it first.

The source has only ever been mapped by satellite, so only inaccurate coordinates are recorded due to the jungle canopy. Explorers from as far back as the 1800’s have attempted to achieve this but failed, due to disease and the dangers of indigenous wildlife. Now Ash is working with international societies to officially map the source of the Coppename River for the first time.
