It takes a special type of person to hold completing one of the world's toughest hard enduro races as one of their confirmed bucket list items. Even more than that, though; it takes a truly singular type of person to actively work toward getting that job done.
Especially if they try it once and don't end up succeeding.
A lot of people might not even have made it to the start line that first time, but quite a few more would throw in the towel and not look back if they didn't ace it on the first try. That's just human nature.
