In alpine skiing, why do athletes encounter the national flag during skiing?

In order to choose the shortest route.

Alpine skiing wins by speed, and athletes have to pass through different types of flag gates continuously when skiing. The flag gate consists of a flagpole and a flag cloth. It is a special equipment for alpine ski resorts, which is used to mark the route that athletes should pass in the competition.

Although athletes are not required to touch the flagpole during the competition, in order to choose the shortest route, athletes basically brush the flag edge.

Rules of alpine skiing competition

Alpine skiing starts by one person in each event, and the starting order is determined by drawing lots, but some events need to ski twice, and the order of the second starting is determined by the result of the first competition. The departure interval is generally 60 seconds, and only the rotating events adopt unequal departure.

When starting, athletes must wear sportswear with official seal (that is, clothes approved by the referee), starting number cloth, helmet, snowboard and ski pole, and must use detachable fixers.
