Biathlon demands a unique blend of explosive speed and absolute stillness—a winter sport where athletes race on skis, then stop to shoot targets the size of a golf ball.
As the Winter Olympics approach, Team USA biathletes Chloe Levins and Deedra Irwin have offered insights into the technical demands of this challenging discipline, which combines the cardiovascular endurance of cross-country skiing with the precision of target shooting.
The sport's central challenge lies in its contrasting requirements. Athletes must push their bodies to the limit during the skiing segments, then immediately calm their elevated heart rates and trembling muscles to hit five small targets with a rifle. As Levins explains, biathlon brings together "two very juxtaposing skills"—Nordic skiing and precision shooting.
The Shooting Challenge: Golf Balls and Grapefruits
During each shooting bout, competitors stop mid-race to fire five shots at five different targets. The difficulty varies significantly depending on the shooting position. In the prone position, athletes lie flat and aim at targets the size of a golf ball—approximately 45 millimeters in diameter. Standing targets are larger, roughly the size of a grapefruit at 115 millimeters, but shooting while standing after intense physical exertion presents its own challenges.
In biathlon terminology, going "clean" through a stage means hitting all five targets—a performance every athlete strives for. Going "dirty" means missing all five, a costly mistake that can destroy medal hopes. The consequences of missed shots vary by race format: in sprint races, each miss results in a 150-meter penalty loop that must be skied immediately. Other race formats impose time penalties instead.
Reading the Wind and Making Adjustments
Environmental conditions add another layer of complexity to biathlon shooting. Wind flags positioned on the range provide crucial information that athletes must process in seconds. Based on these flags, competitors may need to adjust their rifle sights by "taking clicks"—small increments that compensate for wind direction and strength.

"That's actually us changing our sight picture so that we can correct for the wind." These adjustments must be made quickly, as the clock continues running during shooting stages.
When Millimeters Matter
The margins in competitive biathlon are razor-thin. Sometimes shots strike the very edge of a target—what athletes call a "split." In these heart-stopping moments, the target may or may not register as a hit. As Irwin emphasizes, these marginal shots "sometimes are the decider between Olympic medal or not."
This combination of physical endurance, technical precision, and mental composure under pressure makes biathlon one of the Winter Olympics' most demanding disciplines. For Levins, Irwin, and their Team USA teammates, success requires mastering both the explosive power needed on the ski course and the absolute stillness required at the shooting range.
