The X Games return to Aspen, Colorado, this week at Buttermilk Mountain. A marquee event on the yearly snowboarding and freeskiing calendar, the X Games will feature a handful of Olympic gold medalists and notable names in action sports. Below are a few storylines to watch for this week:

Nearly full field of Olympic gold medalists will compete in Aspen

All four freestyle skiing gold medalists in X Games events (halfpipe, slopestyle) and five of six Olympic snowboarding champions (slopestyle, halfpipe, big air) are expected to compete in Aspen. Among them is Chloe Kim, who has not lost a contest since the Olympics. She finished last season with a win at the US Open, and has three victories already this season, including at the Dew Tour in December. Since the Olympics, Kim’s star has only grown: she’s thrown out the first pitch at a Dodgers game and become an awards show regular, but her ability to crush her competition on the pipe remains unchanged.

In addition to Kim, the three other U.S. gold medalists from 2018 should all contend: in men’s ski halfpipe, two-time defending Olympic gold medalist David Wise has continued to impress this season, but as in previous years, he’ll be challenged by his teammates, Aaron Blunck and Aspen native Alex Ferreira, who would skip school as a kid to watch the X Games in person. Snowboard slopestyle gold medalists Red Gerard and Jamie Anderson are both podium threats as well.

After missing Olympics, can Sildaru sweep in Aspen?

Three years ago, a quiet and unassuming Kelly Sildaru won her first X Games title at 13, becoming the youngest ever winner in a winter event. Pegged early as a star for the PyeongChang Games in both slopestyle and halfpipe, the Estonian teenager missed the Olympics with a torn left ACL. Sildaru, who hails from a country with no mountains, will attempt a rare triple in Aspen: she’ll compete in slopestyle, halfpipe, and big air. No winter sports athlete has ever won three gold medals at the same X Games contest. Sildaru missed last year’s event due to her knee injury and has looked sharp so far this season: she won the U.S. Grand Prix in halfpipe and the Dew Tour in slopestyle. Sildaru has four X Games medals in total: two in slopestyle and two in big air.

White’s protégé awaits his big moment

Toby Miller learned from the best: the 18-year-old was mentored by three-time Olympic gold medalist Shaun White, who brought Miller to PyeongChang as his guest. White hasn’t competed since the Olympics, focusing instead on skateboarding, while Miller is having a notable season of his own: he finished third at the Dew Tour and second at the U.S. Grand Prix. The U.S. halfpipe contingent remains deep: Olympians Jake Pates, Ben Ferguson and Chase Josey are all contenders on any given day, though PyeongChang bronze medalist Scotty James will likely be the favorite.

Big tricks

The X Games are often a staging point for new tricks: in 2017, Norway’s Marcus Kleveland became the first to land a quad in competition, only to be topped by Canadian Max Parrot, who won the event with a quad of his own. Chloe Kim and PyeongChang big air gold medalist Anna Gasser have been at the forefront of innovative tricks this season. Kim, a four-time X Games winner, is still far ahead of the field with back-to-back 1080s, which she used last weekend at a World Cup event in Laax. In October 2018, she became the first woman to land a frontside double cork 1080, though she has yet to execute it in competition. Kim can win easily with the arsenal of tricks she already has – but she’d make a bit of history if she decides to go for it.

In November, Gasser became the first woman to land a cab triple underflip, though like Kim, she has not done so in competition. Known for her progressive approach to the sport and impressive arsenal of difficult tricks, Gasser could attempt the triple at the X Games.
