Retiring four-time Olympic skier Marco Sullivan, three-time Olympian Steven Nyman and Olympic women’s slalom champion Mikaela Shiffrin are among those who are back on home snow this week to compete for national titles in the Nature Valley U.S. Alpine Championships in Sun Valley, Idaho.

The nationals are the last competition of the season.

“I always have had a great time skiing in Sun Valley, dating back to my Junior Olympic days in the early ‘90s,” said Sullivan, who recently announced his retirement from Olympic and world cup skiing. “Love the small town vibe, endless groomed runs and then heading to Apples Bar and Grill for some apres. I am definitely looking forward to alpine champs.”

The six-day event includes men’s and women’s slalom Friday, men’s giant slalom Saturday and women’s giant slalom Sunday.

“I’m really excited,” said Shiffrin, who was unbeaten in the world cup slalom events she entered this season. “I feel like I have one more shot at racing GS and hopefully I can go out with a bang.”

The competition will also feature a number of rising U.S. skiing stars, including three-time 2016 Youth Olympic Games gold medalist River Radamus, 2015 super-G national champion Drew Duffy and 2015 giant slalom champion Nina O’Brien. Other defending champions include Olympians Tim Jitloff and David Chodounsky, and Shiffrin in the women’s slalom.

Laurenne Ross, a 2014 Olympian, won the super-G portion of the women’s combined event Wednesday, but the star of the day was 17-year-old Galena Wardle, who won her first national title. Wardle won the competition by finishing second in the slalom; Ross did not finish following a crash at the bottom of the hill.

“It’s a cool hill. I’m still in shock,” Wardle said afterward. “This is definitely a career highlight for me.”
