Mack is a man without a shoe contract to start off the new year, but hopefully that changes for him soon. The full-time running store employee in Raleigh, N.C., captured last February’s U.S. cross country title in St. Louis, prevailing in freezing conditions. He was also the national 8K road racing champion in 2011, and competed at the world cross country championships in 2010, where he finished 67th. Last year he broke 28 minutes for the first time over 10,000m, clocking 27:53 at the Payton Jordan Cardinal Invitational. Most recently, Mack posted a big win at the BUPA Great Edinburgh cross country race in Scotland, topping a strong international field. Look for Mack to defend his national cross country title next month in St. Louis.
