Excellent job, and you logged a lot more than 22 shooting all that selfie running footage! You made it look easy. I've done it 8 times, 7yrs in a row and was lucky enough to get my then teen daughter to do the first 5 in a row with me. Couldn't let '20 deny me, so I trailered a 2nd car, so that I could leave one at each rim. Yes, I'm not right in the head! We've posted a few vids of running in the GC, to the Tube.
Awesome adventure, Brian! That beautiful scenery brings back great memories of my own grand canyon crossings. The key swap is a great idea. And your finishing time is pretty impressive!
