Allyson Felix eyeing a shot at 2 Olympic golds (Yahoo Sports)

Now the IAAF and IOC have done the same for Allyson Felix as she seeks the chance to go for the same elusive track-and-field double. If all goes according to plan at the Rio Olympics, Felix will run a 400-meter semifinal in the evening on Aug. 14. International track and field officials agreed earlier this year to move up the 200 prelims to give the 30-year-old American star a chance to compete in both.
