Jim Ryun quit his European tour after a disappointing third-place finish in the 800-meter run at an international meet in Oslo, Norway. Ryun was clocked in 1:49.6 as Chris Fisher of Australia won in 1:47. Ryun has recorded several poor performances on his tour, which he attributes to hay fever. "I want to go home," he said. "I'm not interested in more defeats in Europe."
