Two men who spent their childhoods in Dayton, Ohio, met yesterday on the streets of Georgetown, with George Nicholas outrunning John Glidewell by nine seconds to win the Georgetown 10K.

"John was something of an idol for me," said Nicholas, 27, a student at the University of Virginia law school who finished the race in 30 minutes 2 seconds.

"George was tough in high school. I'm lucky I didn't have to run him then," said Glidewell, 33, now a resident of Woodbridge.

Cassie O'Neill, 24, who ran one year of track at George Mason after swimming for Tulane University, demonstrated she's well on her way to becoming an elite runner by winning the women's division. She clocked 34:39 on the challenging, hilly course a day after running the Frederick Mile.

Despite running for only two years, she has racked up some good numbers: 33:49 in Pittsburgh two weeks ago and 34:08 in Fairfax last week.

Nicholas (North Carolina) and Glidewell (Ohio State) were all-Americans in cross-country and track in college, and a half-mile after completing a 4:38 opening mile, they capitalized on their speed. By the two-mile point (9:24), only Brian Walter of Blacksburg, Va., and Michael Regan of Washington remained with them.

Then they left flat Canal Road and turned up Reservoir Road for nearly two miles of uphill running. Lanky and long-legged, Nicholas loped up the hills with an easy gait. Glidewell chugged and churned like a steam engine. Yet through miles four (19:24) and five (24:10), Glidewell hung stubbornly within five seconds of his former neighbor. The last hill, up 31st Street from Dumbarton, effectively ate what little reserves Glidewell had and he dropped 10 seconds back; a finishing burst up M Street was not enough to compensate.

Kenny Carnes of Morningside, Md., who finished second last week in the Race of Champions, won the wheelchair division in 25:09.
