I wish I had that option. I know it’s pretty difficult to get a permit, even with the lottery, because so many apply. But it’s definitely doable. I started at 7am and did not leave until 2am – so my headlamp came in handy. I was definitely side-tracked by the beautiful scenery. What really got me was getting up to Asgard’s pass, which was a 1900 ft elevation gain in under a mile or so. I’ve read some hikers finishing the hike somewhere between 12-16 hours. Possibly sooner if you are conditioned and focused on making it through. I did a difficult hike last year – the Bright Angel Trail at GC out to the Colorado River and back in a day. The tail end of this seemed much easier than that hike only because it’s a descent after Asgard’s pass. Definitely need bug spray, maybe a water filter, and lots of snacks. Also, have to pack light and trekking poles will take a bit of stress off the knees. I didn’t have to deal with much snow, which was good, but that could also be a problem, all dependent on the weather. I’m definitely a beginner – intermediate, so this hike really put in check the things I need to work on. And if I did, as many others, I’m sure you can too. Just be prepared.
