Back in the Jurassic period we didn't have GPS and had not yet conceived of FKT's, so my documentation is basic.
First photo of the trip was taken at the South Rim on Monday, April 9, 2007 at 5:22:06 AM (uncertain what time zone, sun was up already so I'm guessing maybe Mountain or Eastern and just hadn't updated it).
I finished on November 6, 2007 at 9:36:00 AM according to a photo by James Q Martin. Hugging mom was the first thing I did.
That'd put me at 213 full days and some change. (Admin note: We're saying 213d 6h, but it must be less - 5:22am ET would be dark in AZ)
