Alastair Humphreys is an adventurer and author. In the past, he has embarked on huge adventures, such as cycling around the world and rowing the Atlantic, but he has found a new passion in micro-adventures and challenges closer to home.

In this classic 'cool conversation', Al tells Kenton about walking across Spain and busking with a violin, sleeping on his local hill, and most recently exploring every inch of his local Ordnance Survey map over the course of a year.

Al is an eccentric adventurer and this is a fascinating conversation.
