Kinda interesting that the ideal body type for these courses seem to be 5'8" to 5'10" at no more than 165lbs. Seems like any heavier will be too much for all the arm sections, and any shorter height or wingspan makes the some of the transitions in some sections too far. Being too tall probably increases the weight too much and puts too much stress on the arms.
When I used to watch the Japanese version on Spike I always thought a skilled rock climber would dominate the 2nd through 4th stages. I wonder if this is a case of this kind of competition is still relatively new so not many good rock climbers competed. Now that there is a million dollars on the line, we'll probably see more high level rock climbers in this. Its too bad the second place guy didnt walk away with anything. It should have been like $100k for completing all four stages. I haven't watched the Japanese version in awhile, but I thought just finishing was considered a victory.
