Reward:

Judging by Reed and Wes' second trial, both look equally muddy, so I will say that their first round is too close to call...

I wish the thumbnail prints were larger too, but I think from this shot...

...which I believe is the start of their second trial, it appears to me that the first one went to Jaclyn....?

Then, after the second trial...Here is Natalie:

Here is Jacklyn:

To me, if I had to bet, I would bet on Jaclyn beating Natalie times 2...

Then, looks like Jon is much less muddy than Jeremy...

Jon winner?

Missy vs. Baylor:

Baylor winner?

If I had to bet on Alec vs. Keith, I would pick Alec to win but?

So, a logical guesses....

Winners: Yellow team: Reed, Baylor, Alec
Blue team winners: Jon, Jaclyn

Logical guess to winners: Yellow team. This might also fit with 2 people offering up their spots in the reward to several others...Natalie could offer to give Jaclyn her spot, if she beats her, and maybe Jeremy would give his spot to Jon, if Jon beats him?
Reed?

IC: Everything must be done with your feet...the pieces to a puzzle are roped up above them. You can see that there are 7 smaller pieces, 7 mid-size pieces, then 7 large pieces. They are secured with tie at the bottom, next to their feet. They must un-tie the secured knot to release all the pieces, that then fall in the basket.

Then they must fit them in the circular puzzle spots in the exact way to solve the puzzle. First one done, winner.

Here you can see where the bundles are tied to the lower post. This is what they must untie to release the pieces into the basket. Then they solve the puzzle with their feet...

By color and Left to right: Yellow = Baylor, Purple = Natalie, Teal = Jon, Green = Keith, White = Jeremy, Orange = Alec, Another Yellow = Wes, Red = Reed, Lime green = Jaclyn, Blue = Missy

Untying the knot....2 styles, Baylor with the 2 feet attack, Nat with the one footed technique...looks like Nat's bundle is falling, see it's lower than Baylor's....

In the following picture we can see that everyone from Keith over to the right is seen...Keith, Jeremy, Alec, Wes, Reed, Jaclyn, and Missy.

In the above picture, we can see that the far yellow(Wes) and red(Reed) puzzles, are almost completed the outer circle of the puzzle with the larger pieces. While we can see the blue (Missy), is almost completed the inner circle close to the post. So, I would say of these people shown, Wes, Reed, and Missy are ahead. If Missy completed her outer circle first then went to the inner circle than she is way out in front. But, since we cannot see her lower circle pieces at all, we can't assume that she started with the outer circle first before moving onto the inner circle of the puzzle.
