Holding on grimly through the final yards, Norway's Ingrid Kristiansen, ran a women's marathon world best of 2 hours 21 minutes 6 seconds to win the London Marathon for the second straight year.
Kristiansen, 29, smashed American Joan Benoit's previous best of 2:22:43 by more than 1 1/2 minutes over the the 26-mile 385-yard course from Greenwich in southeast London to Westminster Bridge. Benoit, the 1984 Olympic champion, set her world best in the 1983 Boston Marathon.
The $75,000 Kristiansen earned -- $50,000 bonus for breaking Benoit's mark, $15,000 for finishing first among the women, $10,000 for lowering the course record -- is among the biggest payoffs in marathon history.
Britain's Sarah Rowell (2:28:06) and Sally Ann Hales (2:28:38) finished second and third. The first American was Katy Schilly, sixth in 2:33:20.
Steve Jones of Wales, who had held the men's world best of 2:08:05 until Saturday, when Olympic champion Carlos Lopes of Portugal won the Rotterdam Marathon in 2:07:11, won the men's division in 2:08:16, a course record.
Jones, 29, ran the fifth fastest marathon ever, breaking the course mark of 2:09:24, set in 1982 by Hugh Jones, no relation.
The next three men's finishers also were under the old course record. Britain's Charlie Spedding, defending champion and Olympic bronze medalist, finished in 2:08:34; Allister Hutton of Great Britain in 2:09:16 and West German Christophe Herle in 2:09:23. The top American was Pat Petersen, sixth in 2:11:23 . . .
Grete Waitz of Norway won the women's and Carl Thackeray of England won the men's division of the 10-kilometer "Sentrumsloepet" race in Oslo.
Waitz's time of 32 minutes flat beat Aurora Cunha of Portugal (32:45) and Carola Haigh of England (34:04). Thackeray won in 29:10. Chris Robinson of England was second in 29:15 and Jarl G. Aase of Norway finished third in 29:16 . . .
Former Georgetown standout John Gregorek of Needham, Mass., outpaced a field of more than 3,000 to win the fourth annual 10-kilometer MDA-Boston Milk Run in a record of 28:15.
Gregorek, 25, came out of the pack to beat another Athletics West runner, Ken Martin, 26, who finished in 28:16. Britain's Paul Davies-Hale, 22, finished third with a time of 28:17.
In the women's division, Monica Joyce, 26, a native of Ireland who lives in Hermosa Beach, Calif., won in 32:18.
