In what was probably the most impressive ultrarunning performance of the year, 23 year-old Kyle Skaggs (who apparently trains with Anton Krupicka) ran a 23:20 at the Hardrock 100-Mile Endurance Run, considered by many to be the hardest 100-mile race in the US. Kyle bested the previous Hardrock course record set by the great Scott Jurek by 2 hours and 45 minutes. Unbelievable when you consider that Hardrock brings 34,000 feet of vertical and 34,000 feet of descent with an average elevation of 11,000 feet. See the video of Kyle's finish below. His record will stand for years.
