OSLO, Norway (AP) — Norway's Therese Johaug won a 30-kilometer mass start freestyle World Cup race Sunday before a delirious home crowd.

She finished in 1 hour, 21 minutes and 17.7 seconds in a dominating performance. Johaug extended her lead from 27 seconds to 48 between the 10k and 12k marks, and then to 1:32 after 24 kilometers.

World Cup champion Justyna Kowalczyk of Poland closed the gap and was runner-up, 46.6 seconds behind in the 18.7-mile race. Yulia Tshekaleva of Russia was third, 51.9 seconds behind. Elizabeth Stephen of the U.S. was ninth.

The result has no bearing on the World Cup standings because Kowalczyk already clinched the title. The Pole has 1,858 points, with Johaug second at 1,197.
