48-hour Goruck “Selection” weeds out the best

Spencer Patterson, of San Diego, James Vreeland, of Detroit, and Grant Shymske, of Fort Bragg, survive the 48-hour GORUCK “Selection” endurance event at Forest Preserve District of Cook County’s Poplar Creek Trail System in Hoffman Estates. The event, based on Special Forces training, demands candidates crawl, march, swim, and be otherwise tested while not sleeping for two days. Patterson, Vreeland and Shymske were the only three of their class of 11 candidates who finished, earning each of them a “Selection” patch.
