Co-Ex is a fantastic single pitch climb on the MF wall. It is considered "the" 5.10 Gunks testpiece... It's rated 10d, but with the correct beta it should feel, oh, about 11a. It's unbelievable to me that the FFA was done in 1967.

Start 20' right of Try Again at a left-facing corner. Climb up to the ledge that's 20 ft. up (a block was broken off here in 2009). Walk 15 ft. right along the ledge, and then follow the broken left-angling crack up and through the overhang (crux), then step left and up to a bolted anchor.


Standard Rack.


A fantastic route with fun moves and a somewhat devious crux. It should be noted that although this climb is mostly well-protected, the opening moves past the first piece of gear are not; however, the climbing is relatively easy. Aside from that, the route eats gear. Oct 18, 2008
Be aware that there is 15-20 feet of R/X 5.8 climbing to get to the ledge. Crux is well protected. Aug 6, 2009

I don't believe that's correct Paul. I remember getting good gear below the ledge. I'm thinking it was around a #0 TCU or something like that. Aug 6, 2009

I seconded this climb, so my comments are based on that perspective.

A fun start to some good face moves lead to a hard crux move. I nearly pumped out trying to make the move over the roof. Aug 8, 2009

Agree w/ Paul. First 25 feet is 5.8 R/X. Beyond that gear is G. Pins at crux are easily backed up and fall is clean! Nov 27, 2011

Incredible climb. You can get a blue tcu 10 feet up, but then its 15 feet of 5.8 to a ledge so the last bit is R. The rest is beautifully protected though. Oct 10, 2012
I'd add that the 5.8 runout is pretty straightforward and on positive holds Sep 4, 2013

I'd recommend not clipping the pitons at the crux, its more strenuous to reach out there to the left than to just throw a solid cam right in front of your face (which I would do anyway) so the pitons aren't really doing a whole lot for ya. Apr 29, 2014

Absolute classic! Gear's great. Definitely clip the pins. Oct 15, 2015

I would like to add that the 5.8 R/X section is very secure on moderately spaced positive holds. If you're climbing at this grade, the start shouldn't keep you off this awesome climb! Clipping the pins is totally unnecessary. Apr 8, 2016
There is a little overlap at the one technical move in the early going-- I have gotten a variety of pieces in there. Small cams and small nuts. I think it is worth placing this one piece. After this one move the climbing is easier up to the ledge. You will be in groundfall range again before you reach the ledge, but the moves are quite easy. Apr 11, 2016

I avoided that 5.8 R/X section by climbing the easier and more protected corner about 15 feet left. I climbed and back-cleaned as I went up, and then walked across the ledge, setting an anchor below the left-leaning crack of CoEx before starting up the route. I later did the 5.8 start on top rope and was happy with my decision to avoid it. Oct 13, 2016
Sean Sullivan (above) has good beta for the start. I did the same start way off to the left but did not back clean. Later the rope worked itself into a crack way off to the left and I had to do a bunch of down climbing to go back and free it. So if you do that start, make sure the rope isn't going to get stuck.

A great 10+ if you're looking to break into 11s or just to try something harder. The first 30' are unprotected even if you get a small 0.1 in under the bulge. Once you're on the ledge, the gear gets really good. Both cruxes are well protected. I took several falls at the high crux on 2 pitons and a solid 0.75.
Top crux beta is: left hand on pinch then right hand on crimp (8 about 10" above pinch on right side) then left hand on jug.
Great climb! Oct 19, 2018
