ST. MORITZ, Switzer­land — Mikaela Shiffrin will skip World Cup races in Switzer­land this week­end after miss­ing train­ing time in speed events dur­ing the coro­n­avirus pan­dem­ic, the Unit­ed States ski team said Tuesday.

The three-time over­all World Cup cham­pi­on opt­ed out of two super‑G races sched­uled for St. Moritz, where she won two years ago.

Shiffrin is now prepar­ing for two giant slaloms on Dec. 12–13 in Courchev­el, France.

“Due to trav­el restric­tions asso­ci­at­ed with COVID-19, oppor­tu­ni­ties for train­ing speed this sum­mer were non-exis­tent for Amer­i­cans,” the team said in a statement.

Shiffrin has not trained since Jan­u­ary for down­hill or super‑G, the team said. She has six of her 66 career World Cup race wins in speed dis­ci­plines, with 59 com­ing in the tech­ni­cal events of slalom or giant slalom.

Shiffrin also has been lim­it­ed by a back injury this sea­son. She placed sec­ond and fifth in a pair of slaloms in Levi, Fin­land — both won by World Cup leader Petra Vlhova.
