No, I didn't hike to the bottom.
But, after my Achilles surgery this past November I was very excited to get a real hike in. I finished my physical therapy/rehab a few weeks ago and I am cleared for most activities that don't involve jumping.
We started at the South Rim and hiked down 3 miles on the Bright Angel Trail. 3 Miles may not seem like a lot (6 round trip), but it was also a 2,100 ft. drop (and climb) in elevation. My ankle was a bit sore (as were a few other muscles) but overall my ankle did fine and I'm happy to be active again.
Here is a shot back up the canyon from the 3 mile rest house.
