Levison Wood explores the Americas for Channel 4
The former army officer will begin his 1700 mile journey in the north-eastern tip of Mexico, heading through eight Central American countries before reaching the Darien Gap where he hopes to pass into Colombia and South America.
The Darien Gap has long been a pull for explorers. The 10,000-square-mile expanse of wild tropical forest stretches from Panama to Colombia and is a refuge for outlaws and dangerous wildlife.
Wood has previously lived in Mexico and trained with the British Army in Belize, but the rest of the trip will see him visit new territory.
