Two of my friends did STP 1 day this year, they were both sent to the ground by someone in the line, one was able to finish but the other was done. 4. Just seems interesting to ride it solo.
My observation is that one can pull easier on a TT bike or with aero bars. The second rider will ride easier in the drops. The third rider should be in low hoods position. For the 4th and later riders, it doesn't make too much difference and comfort and safety take precedence over aero on a long ride.
I've ridden a few one-days and never saw an accident until this year. My last STP was 10 years ago when I was a kid of 59 and finished with a good time. This year I rode it on a tandem with my wife. We were back in the middle of the pack and I did see a couple of accidents. One was a wheel touch. A group of 4 riders in black kit with whom we'd been leapfrogging for a long time mixed in with a bunch of other folks. Someone screwed up and a couple of black kits went down.

Yesterday, I was out on my morning ride on a popular cycling trail and was meandering along about 19mph on my road bike and a hot girl passed me on a TT bike and so I accelerated and hung just a bit off her back wheel and she was averaging 21 mph for a few miles in a perfectly flat back position.
I thought about accelerating around her and giving her a pull but the view was so good from behind I decided to just stay there.
That's all.

On the roadie it's my all day comfy riding position, so that would be sitting up on the hoods, the difference goes down if I'm deep in the drops, and goes down farther when I'm on the clip-ons, I should have specified that in the original post.
I have an admittedly terrible position on the bike (mainly seeking overall fitness, not speed), and I'm also in the neighborhood of 300W for 25 mph (standard road bike with 32h wheels etc.).. but 25 mph with 200W is just crazy, at 200W on the trainer, my heart rate is usually ~100-120 bpm

I had a 56 on my old TT bike, it had 650s though. It's nice cause you can use the middle of the cassette the whole time instead of being at the edges, a nice straight chainline is good for like, a watt, plus it looks awesome.
