Google users playing with today's doodle won't be the only ones trying to make it over the hurdles.
The finals of the women's 100-meter hurdles, one of the most anticipated races of these Olympic Games, will be at 4 p.m. EDT. Americans Dawn Harper, Lolo Jones, and Kellie Wells are expected to make the finals. Harper and Jones are favored to medal.
Jones, from Iowa, is the athlete everyone is watching. She's made a dramatic comeback since her disappointing stumble in Beijing, where she had been favored to win gold, but clipped a hurdle and fell back to seventh place. Since then, Jones has suffered injuries, and many thought it unlikely that she would even qualify for the London Games. She placed third at the US Olympic trials, behind Harper and Wells.
