Woooow! Amazing! Thnx 4 sharing these beautiful mountains and canyon, love it

Went there 22 years ago and did the same thing. Had the body of a powerbuilder because thats the workout I was in at that time. Needless to say physically I was not ready and started cramping up on my way back up. Took 2 extra hours to climb. The crand canyon is one of those places you need to start preparing physically 6 months before if you plan to go all the way down and then back up.

Good job on making a smart choice. Most people would try to keep going.

When I was 20, in 1960, 64 years ago I did the RtoRtoR north to south to north ribbon to south back to the north. I was coming off four years of high school and college track in cross country and so was in very very good condition. Nevertheless it was absolutely as as difficult thing as I ever attempted and coming up right angel Trail the last mile was on my hands. These took me 16 hours, and I finished in the dark without a headlamp so it was pretty damn scary at times wondering if I fall off the edge of the trail as I was hiking by starlight. So I admire your attempt and believe me respect anybody who takes this on. It is quite the challenge. It may be one of the most difficult I took though I think I did a couple ones in death Valley in my 40s that may have ranked in there with the same degree of insanity. 23:54 Thanks for the KZfaq video. It brought back a lot of memories.❤😊 23:54

What a crazy adventure Spencer! Glad you are ok and thanks to everyone who helped you out!

Wow! What a great lesson. Congratulations on making two critical decisions, first to go back up to the north rim, second to go to the hospital. Now I'm waiting to see your retrospective video and to see your long-term recovery.

Thank you so much for sharing your story . I’ve done rim to rim it’s amazing and hard . Took a lot longer than I thought . I developed a knee problem during , ya just never know what will happen in the canyon. Great job ! That’s a lot of elevation change in a short amount of time 👏🏻👍

Great job documenting your story & it ended in success!

There is no shame in calling it a day. On my first thru hike I injured my quad. I am older and I came out to fast. I was on the AT and I normally hike the White Mountains of NH and I found the AT fairly easy. I was putting in way to big of days and loving it. It took me off the trail for 6 weeks, I returned and never had an issue again. Before I had an issue with my quad I felt great. I am sure you had a great adventure and learned a lot. Sometimes we don’t know how far is to far. Take care

Glad your made it out ok and thanks for your video! When will your retrospective on preparing for your R2R2R be posted?

So glad everything worked out!

I’ve wanted to do that for a couple years now. I’d like to backpack it over 3 days, though. Just rim to rim in one day looks rough. Closest I’ve gotten to that was 5,400 feet of elevation gain in 12 miles. Almost type 3 fun, lol. Glad you’re ok!

Beautiful!! Good job!

I just don’t understand the mindset of rushing through such an incredibly beautiful place. Just take your time and look around.

Quite a few years ago, we backpacked rim to rim to rim. It was beautiful and hard, but we did it. I cannot imagine in my wildest dreams the reason anyone wants to do this hike or even a cross canyon hike in one day. To each their own. It's mind boggling to me!

When the muscle cramps arrive, you have to respect and obey . After years of doing intense day-hikes I developed surprise cramps on 2 events : one on Cactus to Clouds only 5 miles from the start, and on San Bernardino Peak trail only 4 miles in. Fortunately the turn-back trip is downhill which spared my muscles. For a strange reason I later developed Peripheral Arterial Disease (blocked arteries) in my lower legs, so now I have to be extra careful and aware of over-stressing my muscles. Now I get muscle fatigue and pain from walking for 5 minutes. I can tough it out, and the fatigue subsides after a while, but I over stressed one time and messed up my right calf. Took almost 6 months to get back to my previous capability. Presently no more marathon day-hikes from me - only short 4-5 mile. Even a 2 mile walk can be difficult.

Great story. Would love to have you on The Grand Canyon Hiker Dude Show podcast to discuss.

HI from the mountains of Colorado. I just found/watched your video and I have subscribed to your channel. I also subscribe to Dan Becker and saw his video about his attempt, and resulting hospitalization. Is there a Rhabdomyolysis test that hikers can take before attempting something like R2R2R?

Best of health, Spencer. A single-day R2R2R is a strenuous hike. I completed it for the second time in early May this year, a week after you were at the Grand Canyon. I wouldn't recommend doing it within a single day to anyone who isn't used to high weekly running/hiking mileage with some steep climbing, on a weekly basis, for many months if not years. We are talking about an ultramarathon strain on the body. Not something one should do without good preparation. Even then, one may have to make some adjustments to avoid risks (see my R2R2R hike video for adjustments I had to make toward the end of my hike). You made the right choice, calling it off, this time. Cheers, and take much care. My R2R2R: kzfaq.info/get/bejne/iLKFq6egxMC1l4U.html

What was the feeling you had that made you, smartly, stay with the ambulance and go to the hospital despite being cleared? What was feeling off?

Have you ever done a rim to rim? This is getting a bit old hearing people get ambulanced and getting lots of clicks. I feel abd for the nps having to bail people out that overeestimate their fitness levels.

Rim to Rim + a hospital trip. Nothing really new there.

Why do people do RTR in one day? It’s nuts! People get injured and die all the time trying to attempt it. At least two hikers have died in the Grand Canyon this year. Don’t be stupid. 🤦‍♀️
