It wasn't all that fun, but there was a certain euphoria about it.

The dirty little secret is it's really just a long walk.

In my mind, its about 25 percent physical fitness, 25 percent mental grit and 50 percent just staying healthy in the altitude. The altitude is the biggest concern.

We were going to go this October, but my wife got pregnant.

I expect because of the full moon and the season it'll be pretty crowded. It's a good season to go: not too hot, not too cold.

There will be something (next).

Because it's Valentine's Day, I've attached pictures of my wife and children to my boots, so with every step, I will have a pleasant thought of my wife and children. They are facing uphill, so it reminds me that they support me.

I think we've all lost some weight, and we've all been training.
