We look ahead to Saturday’s Olympic Trials in Atlanta with 2:13 marathoner Patrick Rizzo, who plans on making this his last race as a pro. With typical heart and candor, Rizzo shares highlights of his career, assesses the governing bodies and drugs in the sport, and offers a glimpse at what comes next. Rizzo picks a few darkhorses to medal on Saturday, and Brenn and Gregg chip in with a few longshots of their own.
