Nice video. Thanks for taking the time to edit and post....
I'm #517 passing from the right @ 9:11 in the video. Bad position for me to be in on the last lap. I think the stronger than usual headwind kept the group together. Normally the pace would really pickup on the 2nd to last lap, string out the group on the hill, and not let up until the finish. Just like you I was going to let this one go but when I saw the field was still together I decided to take a shot. Then I saw that idiot take the suicide line and I let up instead of hammering for the last corner. You can barely see me cruising up the hill at the end of the video.
Just for comparison...
Here's a short clip of SoCal 35+ Masters Racing. Same day, same course. Notice any difference?:
