So you’ve just completed a hard 14er that you thought was impossible until you made it bad alive. And let me guess, you really enjoyed that type-2 fun and are looking for the next challenge.

I did the same thing. So I’ve put together a list of some of the hardest day hikes or ultra run adventures in the U.S. If all of these are new, the “must dos” are Rim to Rim to Rim and Cactus to Clouds, especially if you like vertical gain.

The rest of the list is HERE. I have a bias towards the West coast, but feel free to drop in any comments or additions!
