Canada's Carey Nelson remained undefeated as a marathoner with his second victory, and Britain's Veronique Marot became the first three-time winner Sunday in the wind-buffeted Houston Marathon.

Nelson, who ran and won his first marathon at Toronto last October, pulled away from Czechoslovakia's Martin Vrabel on the 23rd mile and recorded a personal record time of 2 hours, 12 minutes and 28 seconds.Winds of 15 mph crisscrossed the course, causing problems for some runners. Nelson's time was the slowest finish since Ron Tabb's 2:13:36 victory in 1980.

Vrabel ran a 4:51 21st mile and took a 30-meter lead after 22 miles before Nelson moved ahead and captured a 12-second victory. Vrabel was second in 2:12:40.0 and Leonardo Reyes of Mexico was third at 2:13:17.0.

Marot, the 1986 and 1989 Houston winner, dueled with Denmark's Dorthe Rassmussen through most of the race. Marot took the lead for good during the 17th mile and finished with a time of 2:30:55.0.

Rassmussen was second with a time of 2:32:58.0 and Olga Appell of Garden Grove, Calif., finished third at 2:33:18.0. Last year's winner, Paul Pilkington of Roy, finished eighth.

Marot said she was not disturbed by the wind.

"I think it helped me out because it stopped Dorothe from going too fast in the early stages," Marot said. "It didn't bother me."

Nelson earned $25,000 and Marot got $32,000 that included $7,000 in bonuses.
