Oh no! I hope you recover soon!
Your outline here looks great, and honestly -- nothing looks redundant. These are all separate beats that I think make sense for the story of Sequence 7, and if you hit the targets you should be within range of the page count.
One thing to note: when you look at this as a whole, it *is* essentially "the race." So, knowing that, I think I would just try to keep each individual beat as lean as possible. I realize that's like a "Thank you, Captain Obvious" kind of note, but I just mean that this is a big, chunky race section, so just be mindful of not fatiguing the audience. (I know you are already thinking of that.)
This looks solid! You are almost at the finish line! (Am I recycling puns yet?) 😊
