Kuaihuolin (China), May 20 (AP): Spaniard Salvador Calvo set a record over one of the most unusual running courses in the world on Saturday to win China's Great Wall Marathon.

Calvo's time of 3 hours, 23 minutes and 10 seconds was two minutes faster than the old mark, and 15 minutes ahead of Frederick Zalokar of the United States, who finished second in 3:38:14. The first woman was Sara Winter of New Zealand -- an amazing fifth overall in another course record of 3:50:21.

The old record was 4:12:42.
