Ryan Hall (born October 14, 1982, in Kirkland, Washington) is a retired American long-distance runner who holds the U.S. record in the half marathon. With his half marathon record time (59:43), he became the first U.S. runner to break the one-hour barrier in the event. He is also the only American to run a sub-2:05 marathon (2:04:58 at the 2011 Boston marathon). However, this time is not eligible to be a record due to the course being point-to-point and a net-downhill course. Hall won the marathon at the 2008 United States Olympic Trials and placed tenth in the Olympic marathon in Beijing.
