40 Hours to Run 100 Miles in Patagonia

We travel to San Martín de los Andes in Patagonia, Argentina, where we take on a 100-mile ultramarathon with steep climbs, technical trails, and 30,000 feet of elevation gain. We navigate the language barrier, race logistics, aid stations, and dramatic mountain scenery as the run gets underway. After 20 miles, we begin the first night with Nate still feeling strong and ahead of his planned pace.
