I did it, south-to-north last mid-October. I though the timing, both weather-wise and tourist-wise, was perfect.
We stayed at some hotel on south rim night before (didn’t arrive until after dark, nearly hit at least 6 goddamn mooses on the drive in). Planned to get up real early and start well before daylight. Drank too much & overslept. Got to trailhead right at daylight. Very glad we did. I would have hated to miss the stunning view as we started on Kabib. I have never used the word breathtaking in a sentence before now. Like “Hoooo-leeeee fuck!”-breathtaking.
Started out wearing two t-shirts and gloves, and camelback with 70oz water. Within 8 minutes I shed one of the t-shirts and the gloves. Run down, we saw and passed maybe 6 people. Passed one 5-mule train that was coming up. Seemed like we were at the bottom in no time. I would not describe our pace as very quick at all, nice easy jog, stopped to take tons pics, goof off etc.
At Phantom Ranch, you can get a breakfast beer and a bagel for $5 or $6. Also can refill your bladder. I am not 100%, but I think that was the first place we could get water on our route. You can get a real meal there at the ranch too, but I think you are required to order it in advance. I also am pretty sure I had removed my second shirt by then, so I applied a ton of sunscreen while stopped there.
I think on the ascent, we came across three places to get water, and needed them all. I am guessing it was in mid 80’s from phantom ranch to the north rim. I didn’t find the route very challenging at all. I am surprised to read these people saying it was tough. Even the couple guys in our group who were not in super-hiking shape did fine. Maybe those who have said it was tough did it round-trip - we only went one-way. I don’t remember exactly, but I want to say it took us about 8 hours? We hiked/slow jogged the middle 1/3, and definitely hiked the final 1/3.
Here is the one thing that kicked me in the balls - I had no idea I was afraid of heights. Going down, didn’t bother me one bit. I still was unaware of my phobia. But halfway up on the north side, I started panicking inside my head. It was worse because I was bungee-corded onto a guy who was a little slower, so I was pulling him up. We stopped to catch our breaths, and I unsnapped myself, apologized, and said I gotta go, I gotta get the fuck out of here. I spent the next 3 or 4 miles staring straight down at the path and hugging the wall. I even handed my camera to a guy who went ahead with me and asked him to take pictures of what I’m sure was beautiful scenery that I could not look at. And then, jeebus cripes, when another group would come down the path and we had to make room, I really was having some anxious moments.
I guess I should have mentioned, I have some background in running ultras, etc so neither the distance, nor the climb, nor the elevation changes were of any significance to me. Some of the others in my group were slower, as I said, but I don’t think any of them really struggled either. Again, we only went one way. I can see how R2R2R would be a much bigger deal. Overall, I bet we only saw a total of less than twenty people the entire day.
Oh, and if you are really lucky like we were, you have your buddy waiting at the north rim with beer in the car, he can drive you up the road a halfmile where you can get a shower at the campground, then he drives you straight to Las Vegas where you arrive and party your dick off for a couple days.
Overall, one of the coolest things I have ever done. I would do it again in a heartbeat - sheer-dropoff-terror and all.
