Congrats!! That's an incredible accomplishment for sure!!! I would love to do a rim to rim in a day, but I love the inner canyon so much that I never want to rush myself and leave without exploring to my hearts content.

We spent 4 days in the Canyon this summer. We went down and back up the North Kaibab. Going back up was TOUGH with a capital T (especially carrying a 35 lb pack). The last 2 miles out after Supai tunnel was the toughest by far- like walking uphill on the beach.

I trained like a maniac for it, and even though I'm in very good shape- it kicked my tail and took no mercy. I *DO* love that canyon, though!!! Next summer we're thinking of taking a far less-traveled trail and really being alone in the canyon. Woot!
