The Deadliest Sports on Earth: Ranked

High-Altitude Mountain Climbing

This is a whole different beast compared to traditional mountain climbing. When you attempt to summit peaks like Everest and K2, you need to bring supplemental oxygen to sustain yourself so you don't pass out from altitude sickness. Hundreds of individuals have died while trying to climb Everest alone. Make sure you know what you're getting into before you give one of these summits a shot.
