EUGENE, Ore. – Now that everyone knows which two races Allyson Felix will run, it’s time to find out if Tyson Gay is fit enough to win even one.

Over the next 10 days in Eugene, two of America’s best-known sprinters will try to qualify for a trip to the London Games, but while Felix heads into Olympic trials at the top of her game, Gay remains a question mark after months of struggling with injuries.

Felix finally ended the drama and said she’ll try for the 100-200 double, instead of the 200-400 she’d been training for over much of the past year.
