Ryan Hall - 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. He is now coaching other runners and heavily into strength training.
