Think about compression, distance, and distortion.
What that means is that the elements will look closer.
If you shoot with a wide lens up close to the athlete, the mountains will look particularly small.
This is a great method to incorporate more environment into the shot.
Shoot fairly close with a wide-angle and your subject still looks fairly big.
Move back a bit with the same lens if you want the subject to appear smaller.
The wider you go, the more stretched out and rounded your image will appear.
Obviousely a fisheye is designed to enhance this distorted look.
It also makes features such as jumps and cliffs look much bigger.
This is great if you want blurred elements in the foreground.
Wide lenses can't achieve as shallow of depth as zoomed lenses.
