The 9 Toughest Ultramarathons

Used to be that running a 50- or 100-mile race earned you bragging rights for life. No more. Today, the word “ultra” has been slapped on laundry detergent, lite beer, and any marathon that takes a step beyond 26.2 miles. It seems like every endurance runner is prepping for one.

They’re extra long, incredibly tough, and take the type of commitment and logistics once needed for climbing a Himalayan peak, all brought to bear in some of the world’s most dazzling landscapes. Think you have what it takes?
