Kara Goucher, one of the top U.S. marathon hopefuls for the 2012 London Olympics, will make her road-racing return from maternity leave at the P.F. Chang's Rock 'n' Roll Arizona Marathon & 1/2 Marathon. Goucher, 32, will run in the 1/2 half-marathon on Jan. 16 like fellow U.S. running stars Ryan Hall and Deena Kastor did in 2010. She also could run in the 2011 Boston Marathon in preparing for the U.S. Olympic Trials in Houston on Jan. 14, 2012.
