This is about extway

Ice climbing is a type of climbing.

Extreme sports differ from standard sports due to the relatively higher number of inherently uncontrollable variables in extreme sports. Extreme sport athletes compete not only against other athletes, but also against environmental obstacles and challenges. These environmental variables are frequently weather and terrain related, including wind, snow, water and mountains. Because these natural phenomena cannot be controlled, they inevitably affect the outcome of the given sport or event.

In a standard sporting event, athletes compete against each other under controlled circumstances. While it is possible to create a controlled extreme sporting event, there are often variables that cannot be held constant for all athletes. Examples include snow conditions for snowboarders, rock and ice quality for climbers, and wave height for surfers.
