LIBEREC, Czech Republic — Justyna Kowalczyk won her second gold medal at the Nordic skiing world championships today, winning the women's 30-kilometer cross-country race 1 hour, 16 minutes, 10.6 seconds.

Kowalczyk secured the freestyle race by pulling away from seven rivals in a tough uphill climb less than a mile from the finish.

Russia's Evgenia Medvedeva won a sprint for silver, finishing 8.8 seconds behind. Ukraine's Valentina Shevchenko was another 0.5 seconds back.

Kowalczyk also won the 15K skiathlon pursuit last Saturday, after taking bronze in the opening 10K classical race.
