[3] Jacobellis also won gold (with teammate Nick Baumgartner) in mixed team snowboard cross at the 2022 Winter Olympics in Beijing.

[5] As a young child, she was primarily a skier, but she switched to snowboarding after the family's home burned when she was 8, destroying all her gear.

During the snowboard cross final, Jacobellis was approaching the end of the course with a 43-meter (140 ft), three-second lead over Tanja Frieden of Switzerland.

On the second-to-last jump, Jacobellis attempted a celebratory method grab, landed on the edge of her snowboard, and fell.

[9][10] At the 2007 Winter X Games, Jacobellis lost the lead in a fall near the finish line in snowboard cross.

Jacobellis failed to progress to the medal round of snowboard cross at the 2010 Winter Olympics in Vancouver, as early in her semifinal race, she landed badly during a jump, and to avoid a collision with another rider, went through a gate, resulting in automatic disqualification; she then slid off the course.

The New York Times reported that in the period between the 2014 and 2018 Olympics, in addition to her training, surfing, and other competition strategies, Jacobellis also began working with the mental skills coach Denise Shull.

[16][17] Jacobellis followed up her individual gold by winning the debut of the mixed team snowboard cross with partner Nick Baumgartner.
