Rampage allows riders to choose their own lines and make them as risky as they want. Plus, it’s not a race. Nor is jumping out of a balloon.
I agree that both of those still have their inherent risks, but at least they allow the participants to largely be in control of their own lines/destiny and don’t have the race against the clock element.
As frosty said above: To win a race of this nature you’d have to be almost suicidal. The Rampage, and all other urban dh events (for want of a better phrase) there are opportunities designed into the course for riders to check their speed accordingly and it becomes a game of skill, as much as fitness and nerve. This had none of that.
For Redbull sponsored riders, I’m sure they are “encouraged” to take part.
