U.S. Olympic track and field trials were briefly suspended Sunday because of extreme heat in Oregon as temperatures soared to about 108 degrees on the course and caused at least one competitor to withdraw and some fans to be evacuated.

The trials were shut down at 3:40 p.m. ET with six events remaining and resumed around 8:30 p.m. ET. The forecast high for Sunday at Hayward Field was 111 degrees, but only three long-distance races were moved from the afternoon to the morning because of the heat.
