Ultra running's most secretive and brutal race has gotten underway in Tennessee with a dramatic start that saw two runners disqualified in the opening moments.
The Barkley Marathons, famously dubbed "the race that eats its young," kicked off at 5:17 a.m. on Wednesday in Frozen Head State Park. The 100-mile race consists of 5 laps of a 20-mile circuit and is known for being extremely challenging and highly unusual.
