Oops. This part of the previous post was mine. Sorry, Short and Simple!
Yes, it's Shorter, by a long distance (ahem). An Olympic gold medal in the marathon, then a silver medal, losing to a doping East German. And I raced against him in a 10K in 1981 in Glencoe, Illinois. A small local race with maybe 100 runners that passed through the Ravines, one of the very few hilly places in the Chicago area. He showed up unannounced, won, and quickly left. Stealth racing.
