What you need to know about Ultramarathons

An ultramarathon is any running race longer than a traditional marathon of 26.2 miles. Most of them take place on trails, often surrounded by spectacular scenery, and involve continuously stuffing your face to keep your body going mile after mile. At the extreme end, ultras can involve running more than 300km over multiple days through mountains, deserts, jungles and snow. But if this is your first ultra, you might want to start with something a little shorter, like a “gentle” 50km.
