McNeely completed many one-day (i.e. under 24 hours) big wall aid climbing routes on El Capitan including Eric Kohl's Plastic Surgery Disaster (VI 5.8 A5), Warren Harding's Wall of the Early Morning Light (VI 5.9 A2+), John Middendorf's Atlantic Ocean Wall (VI 5.8 A4), and one of the hardest aid climbing routes on El Capitan, The Reticent Wall (VI 5.7 A5), along with Dean Potter & Ivo Ninov in 34 hours and 57 minutes.

In 2011, 29 years after the first ascent, McNeely with partner Kait Barber made the second ascent of the aid climbing route Wings of Steel, with the purpose of examining the controversial methods of the first ascent team; their climb was documented in the 2013 Jeff Vargen-directed film, Assault on El Capitan Some of McNeely's other El Capitan speed climbing records include: In October 2013, Ammon nearly lost his foot in a BASE accident in Moab that he described: "We were with one other jumper who was new, and I voted that Andy goes first, the two new guys go in the middle, and I go last.

I jumped, probably took a tad longer delay than I should have, being it was a new exit with new brake lines, and immediately had a 180-degree opening.

I knew I was banged up, but to my utter surprise my foot was flipped on its side looking very similar to a Nalgene bottle with just a sliver of skin keeping it on."

As Ammon was trying to sit down, he lost his footing under his prosthetic leg and fell backward off the cliff.
