A brand new Olympic sport, ski mountaineering, will debut at the Milan Cortina Games

The Milan Cortina Winter Olympics will debut a new sport next month: Ski mountaineering, which combines uphill sprinting (on boots and on skis) and downhill skiing. Although the sport on the global stage is relatively new, it does have roots dating to the late 19th century. Backcountry winter sports have grown in popularity and there is anecdotal evidence that they saw a surge in participation during the pandemic.

Something to know about skimo: It's fast, with sprint races lasting about 3 minutes.

How it works

Ski mountaineering will have men's and women's sprint events along with a mixed relay.

The race works like this: The racers sprint uphill with skins on the bottom of their skis. A skin is a strip of material that allows for traction going uphill. They then run a section in boots before putting their skis back on to traverse another uphill section. Once at the top, they take the skins off and race downhill. In the men's and women's sprint-event format, there will be a qualifying round where 18 racers qualify over three heats. The top three athletes in each heat advance to the semifinals along with three others based on time. In the semifinal rounds, two advance along with two more ''lucky losers," which sets up the race for medals. The mixed relay consists of one female and one male racer from each country. Each will complete two ascents and descents. The female athlete begins, then tags her male teammate for the switch. The team that completes all four laps first wins gold.

Who to watch

The current ski mountaineering sprint champions are Swiss racer Marianne Fatton and Spain's Oriol Cardona Coll. Another favorite is France's Emily Harrop, who won the test event at the venue last winter ahead of Fatton. Coll won the men's event ahead of Swiss racers Jon Kistler and Arno Lietha. In the mixed relay event, Coll partnered with Ana Alonso Rodriguez for the win. Harrop and Thibault Anselmet were second. Rodriguez said in October she was hit by a car while cycling, tearing knee ligaments, hoping to heal in time. The U.S. earned an Olympic spot in the mixed relay thanks to a World Cup victory from Anna Gibson and Cam Smith.

The races will be staged in Bormio at the Stelvio Ski Center, with the men's and women's sprint events taking place on Feb. 19. The mixed relay competition takes place two days later.

Memorable moments

The medal winners will be the first in their sport at the Olympics.

Fun facts

There are penalties in the race for things such as disrespectful behavior, unsportsmanlike conduct, technical errors and equipment that's missing. The penalties range from a disqualification to adding time. The first ski mountaineering world championships were held in France in 2002. The sport is presided over by the International Ski Mountaineering Federation (ISMF), representing roughly 55 national federations across five continents. Ski mountaineering was part of the 2020 Winter Youth Olympics in Lausanne. The sport is proposed for the 2030 Winter Games in the French Alps.
