Don't Break the Ice!

I'm on a team with 2 other people that I seem to know, but not in real life. We are supposed to walk across this huge field which is made of 2 feet wide blue cubes all wedged together. They are suspended about 30 feet in the air. The cubes are not quite lined up together height-wise and some are looser than others so it is like crossing a rock pier except suspended in the air. The first team across the entire field wins of course. We start crossing and then there is a break in the cubes where you'd have to jump about 15 feet to get across. There is no way that we can jump that far, so I told the rest of the team that I was going to go back, climb down and walk to the other side. This would mean taking penalty points but I didn't see anyway around it. I wasn't going to try jumping across a 15 foot span with a 30 foot drop. My other teammates start getting angry with me but one follows me down. By the time we reach the break, we look up at the suspended cubes and the other teammate is still yelling at us that we need to jump. He said it wouldn't hurt if we fell. The floor is a gym floor covered in interlocking black rubber squares, somewhat padded, but not enough in my eyes. Then the teammate above leaps off and lands flat on his face with a huge thud. I turn away, not wanting to see the aftermath, but the other teammate runs over to him immediately. I start walking the other way, imagining the blood and mangled bones and wishing that it didn't happen. Miraculously, they come running up to me to show me that he is alright. Now, he gets angry with me for walking away. I start to apologize for walking away and that I didn't mean to desert the team and I feel terrible. I wonder how it is that he isn't hurt. Perhaps I'm in the Matrix...

Observations: This cube setup is very reminiscent of the game Don't Break the Ice and also this build-your-own arch from the Ecotarium in Worcester MA.
