LONDON -- All three U.S. runners entered in the 5,000-meter run, including 10,000 silver medalist Galen Rupp, advanced through qualifying on Wednesday into Saturday's Olympic final.

Rupp ran 13 minutes, 17.56 seconds to advance out of the same preliminary race as teammate Bernard Lagat, a 37-year-old four-time Olympian, who ran 13:15.45. Moving on from the other heat was Lopez Lomong, in a time of 13:26.16.

Other qualifiers included 10,000-meter gold medalist Mo Farah of Great Britain, who trains with Rupp in Oregon. Farah ran 13:26.00.

Meanwhile, Brad Walker, who no-heighted at the 2008 Beijing Olympics, was the only one of three American pole vaulters who got through qualifying. Walker, a University of Washington grad, cleared 18 feet, 4 1/2 inches. Teammate Jeremy Scott scaled 18-0 1/2 but did not advance and Derek Miles, a Sacramento native competing in his third Olympics, did not clear a height.

Finals in the pole vault are Friday.

As expected, none of three U.S. entries in the women's hammer throw qualified for the finals.
