David McCormick of Falls Church did not give history a chance to repeat itself. Last year at the Georgetown 10-kilometer run, the 23-year-old George Mason University graduate student lead the entire race until he was outkicked by Todd McCallister with 50 yards left.

Yesterday, McCormick again shook McCallister after four miles, and anxiously waited to hear McCallister's pursuing footsteps that never came. This time, McCormick prevailed in the fifth annual 6.21-mile race in 30 minutes 27 seconds on a warm, humid morning in Georgetown.

McCallister was second in 30:33, and Tim Gavin of Gaithersburg placed third in 30:52.

Patty McGovern of Washington passed runner-up Karen Wagner of Argustus, Md., after one mile and easily won the women's division in 35:59. Wagner and Annemarie Jutel of Charlottesville followed in 37:15 and 37:41, respectively.

"I didn't want the race to come down to the finish," said McCormick, racing 23 seconds off last year's time and 27 seconds off McCallister's 1983 course record. "He's a sub-four minute miler. So I ran the uphills (at the three- and four-mile marks) hard to get a big enough lead early."

Jim Hage of Rockville, who brought the field of more than 2,600 starters through the first mile in 4:36 and the second in a fast 9:24, finished inches ahead of Tim Tays of Gaithersburg for fourth. Both runners were clocked in 31:00.
