The RC:

They must run to the corral and untangle the rope first. We see that Spencer is way out in front, he's already untangled while the others remain back at their corrals...

Once they get the rope untangled, they bring the rope with them, and pick up the slats and place them across the beams to scale across. Here is Kelley arriving, note Abi, in purple, is still working on untangling....

Then here is Tasha placing the slats and climbing over the beams....

Note, that when Tasha is scaling the beams, that Jeremy, who was in yellow, is already beyond the corral.

Conclusion: Three people go to the reward. Jeremy, Kimmi, Abi are losers and stay behind.

I bet Keith, Kelley, Spencer go on reward. I am leaning toward Spencer winning this challenge as well, so he could possibly choose Kelley and Tasha to go on reward? Tasha is in the mix.

*I just want to say that I think this challenge severely favors the guys. Most girls I know are not nearly as adept at throwing balls as guys are. (with accuracy, that is!) Just saying!

The IC:

We see the puzzle stations have a large box beside the stations, a box that must be unlocked with a key...

Here is the beginning of the challenge, note Jiffy's platforms off to the side, there are 7 wider parts of that platform.

This is not a press image:

Here is the back half of that challenge, noting again where Jiffy's platform ends...

Note the floating buoys off the last floating platform. The keys are clipped to the buoys and they must unclip and retrieve them.

Here are the DAWS at the start:

Towards the beginning of the challenge:

Jeremy taking the lead, then Spencer, then Kelley, Keith, Tasha, Kimmi (who is under water behind Kelley), with Abi in the rear.

*I am thinking since they have to retrieve a key, that they most likely only have to run this course ONE time. Once they have the key, there is no need to go back. Perhaps, there could be multiple locks on the boxes? Idk? But, for all intents and purposes, I am going to ASSume that they only run it one time....*this could be a wrong ASSumption*....

So, if they only run it once, then this picture comes next.

We see Jeremy out in front, swimming toward the buoy to get his key...then we see Spencer climbing back up on the platform, just prior to the boats, while Kelley and Keith are just off their platforms and running on the section where they run in water, just approaching the same platforms that Spencer is climbing back up on. Did Spencer miss the first boat, fall in and have to climb back up? I think so, because I don't think there is anyway that he could have ALREADY retrieved his key and be returning at this point with all of them right there.

Then, next we have these 2 shots, that show us that Spencer has recovered and is back out in front, now getting to the final platform before swimming to get the key.

At this point, as they approach the boats towards the end of the course, Jeremy is not seen, he's out in front, then Spencer, then Keith/Kelley, Tasha, and Kimmi and Abi are not seen. (They are in the rear)

Then, Jeremy out in front, then Spencer, Kelley is passing Keith here, then Tasha.
*Jeremy is ALREADY swimming to his buoy when Spencer falls in prior to the first boat at the end of the course, so I think he has a pretty substantial lead. If this is a straight forward puzzle to solve, Jeremy could win it.

Here are Kelley and Keith, who have been neck in neck the entire time, at their buoys unclipping their keys...

And, Tasha:

Here she is diving from the last yellow octagonal platform to get her key/buoy...

She looks like she is getting there by swimming on her back to the buoy....

At the buoy:

Then getting into trouble...

Spencer will get to his puzzle station well after Jeremy, because here we seem him returning with his key and he falls in AGAIN...

So, for me, Jeremy wins the race to get back to open the box to begin the puzzle, while Spencer struggles to get back, but most likely does begin his puzzle in second place. Will it be enough time for him to solve the puzzle in first?

***ETA: The other scenario is there are multiple locks on the puzzle boxes and they must run the course multiple times. We see that Kimmi, Spencer, and Kelley, most likely Jeremy and Keith as well, are on the beach when Tasha screams that she needs help. Does she struggle SO much that Kimmi is already back with her key when she screams, OR are there multiple times to run that course?

If there are multiple times to run the course, I predict that Spencer could catch Jeremy? Idk?
