Way to go brother. Here's the thing about the show, when established makers inter the show, they have everything to lose. When un-known makers compete, they have everything to gain. Anything can happen. If you want something to go wrong, point a camera at it. It takes real guts for an established guy to do that.
When the filming is all done, the competitors know the outcome but we don't know what will be on the show. Because it's a show, all or most of the mistakes we make go in it, it just makes for good TV. On the contrary, they don't have enough time to put in all the things that we got right. It's more exciting to the viewer to see the things that went wrong than it is to see what went right.
All that having been said, the show is a ton of fun, one of the most positive things I've ever done. It forces you to get out of your routine and challenges you to do thing you would never think of doing. The rewards go for beyond the prize money.
Kudos to you my friend, go Alaska
