Video: Lessons From the Edge - Running the Great Himalayan Trail

Earlier this year, endurance runners Ryan Sandes and Ryno Griesel completed the grueling undertaking of running the entire length of the Great Himalaya Trail. The two men covered more than 1400 km (870 miles) in just 28 days through some of the most rugged and remote terrain imaginable. Now, we'll get a chance to join them out on the trail in a three part series entitled Lessons From the Edge. The documentary will debut later this month, but you can get a preview of what to expect in the trailer below. Judging from what we've seen here, viewers are in for one heck of an adventure.
