LOS ANGELES (Reuters) - Unseasonably high temperatures will challenge runners at the U.S. Olympic marathon trials on Saturday with the top three finishers in the men's and women's races earning spots on the United States Olympic team.
A record field for the trials, comprising more than 370 athletes, will have to cope with temperatures of up to 82 degrees Fahrenheit (28 Celsius) in downtown Los Angeles where the race will start and end.
