12 Hours since race started.
Here is my official "Diploma" with all of my time splits and my final official time: 4:33:55.
FYI the difference between the "Real" time of 4:33:55 and the time of 4:49:19 is because it took us about 15 minutes to actually get to the start line from where we were being staged after the starting gun had been fired and the clock started. I started my watch when I crossed the start line and stopped it when I crossed the finish and my watch has 4:33:53 on it...so taking into account a couple of seconds of error, 4:33:55 is the time it actually took me to run the 26.2 Miles /42.2 Kms. We were so far back from the start line, I probably walked an additional 1/2 Km before we got to the start line. We didn't even move an inch for about 5 minutes after they said "Et c'est parti" ("and they're off").
More thoughts on the experience after I get some shut-eye. Anita and I just returned from a lovely dinner at a quaint bistro just off the Champs Elysees, complete with a requisite rude French waiter...a true Parisian experience :-)
