In ski jumping, the lines on the hill indicate different levels of difficulty for each jump. The closer to the bottom of the line, the shorter and easier a jump is. As you travel up the line, jumps become longer and more difficult. Knowing which lines to choose can be tricky; if a skier chooses too difficult of a line, it could lead to an unsuccessful jump. However, choosing a line that’s too easy can cause the skier to miss out on points and potentially lose the event. It is important for ski jumpers to be aware of the lines in order to make the best possible jump.
