I often do ultra races, always trying to be at the pointy end. I have all the training, and all the fancy equipment you could possibly imagine. Doing something of the magnitude of this article though still scares the hell out of me. Every year I watch the Transcontinental Race, and every year I say "yeah, would love to do it, but next time". I still haven't signed up.

The gear, the legs, they help with going faster. Whether or not you can finish (barring catastrophical mechanical or injury) is all in your head!
