They ran. They swam. They tugged and tossed. Hundreds of athletes from dozens of companies competed last weekend in the OU Medicine Corporate Challenge, the largest business-to-business athletic competition in the Oklahoma City area. It was the 22nd annual event to bring together small and large companies to compete against companies of equivalent size in a variety of track and field events. Medals and trophies were awarded to the winning athletes and teams. Lead sponsors for the three-day event were Chesapeake Energy, Farmers Insurance, Office Max, the Oklahoma City-County Health Department and OU Medicine. Results are online at www.oumedicine.com.
