I agree with DopeyBadger's analytics, i.e. that the photo op lines will get longer as the day progresses, so the faster runners / earlier starters should (in theory) have some shorter lines and be able to get their pics and keep moving.
As for riding ToT, I'm hoping that begging might work. ("Hey, brother. Can you spare a lone-rider space for a poor runner trying to stay ahead of the sweepers?")
Tapering - Since I'm still trying to get below the 200lb threshold, I'll keep up with my every-other-day runs through the end of the year, weather permitting. My guess is that weather and time with the family will create some tapering regardless. I did 6 miles on Sunday on the flat-ish greenway with no walking or stopping and that will work for me, as noted in earlier posts. Easy runs on Thur and Fri, and a Galloway-style mix of running with walk breaks at the water stops on Sat. Sunday.... run, walk, take breathers while waiting for photo ops.
Which leads to.....
I did 4 miles today on my neighborhood course with the two hills (thank you 63-degree weather) and did 4.0 miles in 40 minutes!!!
To put it in perspective, on that some course, it was 12+ minute miles back in August and dropping down to ten-and-a-half minute miles in October. It's nice to have tangible progress.
