After regaining their consciousness, some of the more intelligent people immediately realized that dealing with Mira was a huge pain in the ass and decided not to mess with her. So, instead of competing against Mira on the same playing field, a few of them decided to run down the mountain to steal someone's token without Mira's interference.
Most of the people that made it to the top of the mountain hadn't even considered this, and for a good reason. They just spent the last 20 hours climbing up a mountain. Why would they want to go back down?
However, they soon concluded that dealing with Mira was much more annoying than running down the mountain to ambush an unsuspecting participant. Not only that, but as long as they aren't complete idiots, taking a token from someone who is still running up the mountain should be easy.
