Easy to see that there are 2 challenges at F4. So, one for a heck of a reward, ? advantage, think Keith in the second Bl v Water. Perhaps an advantage for the IC, or perhaps something else? Here are the 2 challenges:
We can see Jiffy on the top level of the challenge, but I do not see any sign of the IN so perhaps this one was for reward...

Michele: Orange
cydney: blue
Tai: Yellow
Aubry: Red
The next challenge is seen here:
Looks like there are stages this to this challenge. First they race through obstacles to get at a station where it looks as though Aubry is in the lead....
Then they go under or over netting, over obstacles, then across a balance beam, to another station and it still looks like Aubry is in the lead...
