The fastest recorded speed for a ski jumper was approximately 252.0 km/h (156.2 mph), achieved by a jumper named Anders Jacobsen in 2011 during a competition in Norway. Ski jumpers accelerate down a ramp before taking off into the air, utilizing their body position and aerodynamic techniques to maximize distance. Achieving such high speeds significantly impacts the jumper's performance, emphasizing the importance of both technique and physical conditioning in the sport.
