Warming up on vault during a meet.
Rodeo
The Nevis bungy (NZ) is very high. You go 80mph.
It helped that I used to do diving. Nonetheless, I had to avoid looking down while on the platform.
The Kawarau Bridge (NZ) was the world's first official bungy jump.
I did an all-natural solo triathlon in Grand Teton National Park.
I swam 1.0 mile across Leigh Lake (cold!), walked 2 miles barefoot, and biked a few dozen miles to get from home and back.
No combustion engines were used to get anywhere. Some nice strangers took the picture with my camera.
