Altitude training is defined as training at least how many meters above sea level?

• A. 1,000 meters
• B. 2,000 meters
• C. 2,400 meters
• D. 3,000 meters

Answer: (C)

Altitude training relies on the body experiencing hypoxia from thinner air at elevation, which stimulates adaptations that can improve endurance once you return to lower elevations. The threshold used in many practice materials is about 2,400 meters above sea level. At or above this height, the reduced oxygen availability reliably produces the physiological stress that prompts responses such as increased red blood cell production and improved efficiency of oxygen transport. That’s why training at or above this height is categorized as altitude training. Lower elevations like 1,000 or 2,000 meters don’t consistently produce the same hypoxic stimulus, while 3,000 meters also qualifies as altitude, but 2,400 meters is the defined minimum in this context.
