Karl started running in High School, after the cross country coach noticed his talent while he was playing soccer for the school. After a successful high school career, he went to run at Columbia, where he had a great four years of running. After college, he joined the Manhattan Track Club (MTC) and continued to train. While running the Chicago Marathon in October of 2006, he qualified for the 2008 U.S. Men’s Marathon Olympic Trials. Running the Trials in November 2007 in Manhattan was one of the best experiences Karl has had during his running career.
Karl met Emily in Manhattan and they were married in September of 2008. Karl decided to get his MBA full-time at the University of Maryland, and he and Emily moved to the DC area in July 2009. Emily went to high school with Matias who introduced them both to GRC. Karl and Emily recently welcomed their first child, Lily Clare, on September 17, 2010. Karl is hoping to qualify for the 2012 Olympic Marathon Trials and recently set the GRC Club Record for 5 miles in 24:03. When he is not running, Karl enjoys playing other sports and watching TV.
