EJs take is really interesting:

“With 26 countries and the worlds fastest slalom racers, creekers, expedition boaters, freestyle kayakers, etc.. all competing, I am comfortable with the idea that this is the World Championships of Extreme racing. No race in the world has a stronger field. Green race has a very strong field but nothing like this. This is the real deal with huge depth of field. Any time you have 10 people stacked into 1 second, you have a strong depth of field. That is pretty awesome. 60th place was only 6.25 seconds behind 1st place in a single run. That is an average of 10 people in each second.”
