The Four Day Climb August 29 - 1 September was unable to reach the summit today due to route conditions. RMI Guides Pete Van Deventer and Dominic Cifelli lead their teams to Ingraham Flats at 11, 200', they enjoyed the views as the sun came up. The team is now back at Camp Muir and will begin their descent to Paradise later this morning.

Hello all,
Today we woke to perfect weather to hit the trail. A mellow walk past yak corrals took us to our first uphill. A little more breathing and some sweat brought us to a downhill trend to the river crossing. Before we crossed, the team enjoyed an ice cold foot soak. Shortly after the river it was tea time. The saying out here might go Dal Bhat power 24 hour but I think for us its hot tea power 24 hour. After filling our energy tanks with tea we madr our way up the last hill of the day. The top of the hill brings us to a special place, the climbers memorial. A sadness fills this place but also brings to reality the risks taken to climb mountains. After acknowledging those who have fallen we continued our journey to Lobuche. Not far from the town we pass by the Lobuche peak Basecamp. We gaze at our objective but first we must go to Everest Basecamp. A little training in the evening brought us to dinner. A birthday cake surprise wrapped up our day with smiles and chocolate covered mouths. Another good day in the books and more to follow.
Goodnight all,
RMI Guides Adam, Hannah, and team
Weather is your blessing!! Hoping it continues for you! Beautiful photos!

RMI Guides Adam Knoff and Ben Ammon led their Four Day Climb teams to the summit of Mt. Rainier today. The weather is clear and cold and the climb took approximately 6 hours from Camp Muir to the crater rim. After enjoying some time in the crater and getting all the photos, the team will return to Camp Muir to pack up and then continue their descent to Paradise later today. They will end their adventure with a celebration at Rainier BaseCamp.
Congratulations to today's climbing teams!
Great job! Congrats!

Climbing is a long and demanding endeavor, with a typical summit day on Rainier or Denali stretching for twelve to fifteen hours. Every time you take a step, your muscles require energy in the form of ATP to be able to fire. ATP is created within the muscle cells by mitochondria from two main nutrients: carbohydrates and fat.
For many years, athletes have focused on their carbohydrate intake as the key to performance. Carbohydrates provide a readily accessible and easily digestible energy source for your body, which is the reason that they are the main content in most sports foods; just look at the labels of shot blocks, Gu’s, bars, energy drinks, and the like, and you will see a heavy focus on sugar. There is a good reason for this: your body has a limited ability to digest food while exercising (digestion requires energy of its own), and carbohydrates and sugars are the easiest to digest, requiring little to be done to the glucose components before they enter the bloodstream and are carried to the cells.
The main issue with a reliance on carbohydrates is that your body has the ability to store a finite supply of glucose in the muscle cells and the liver in the form of glycogen. For trained athletes that are efficient with their energy usage, that store still only lasts for about 2 hours of sustained hard effort. If you aren’t familiar with the term “bonking,” it’s that feeling when your performance drops off a cliff; you don’t feel like you are working that hard aerobically, but you can’t possibly go any faster or harder. You’ve run through those glycogen stores and your muscles are out of fuel. Eating while you exercise can help to delay bonking, but your body can only process about 250 Kcal of sugar per hour, far less than you expend over the same period. Even though we are replenishing our sugar fuel, we dip further and further into those reserves as summit day goes on. At the same time, even the leanest among us carries over 24 hours of energy in the form of fat stores. Wouldn’t it be nice to recruit those stores while you are climbing?
Fatty acids are the most energy dense nutrients in our diet and our body stores them readily. They create more ATP per unit than sugars, and our body’s ability to store them can leave us with a huge reserve energy supply. The problem is that when fatty acids and sugars are both present, our metabolisms preference burning the sugars for energy. Julia Goedecke is a sports scientist who has been examining the influence of fat oxidation (metabolism) in endurance athletes. In examining rates of fat oxidation in athletes at different intensity levels, she found a vast difference in overall rates of fat oxidation. Some burned nearly no fat at rest, while others metabolized nearly 100% fat at rest, but while there were differences in overall rates of fat metabolism, those who metabolized more fat at rest derived more of their energy from fat at all intensity levels too. This would suggest that if we can train our metabolism to derive a greater percentage of our energy from fat, it will continue to do that as we up our intensity climbing, and we will use our sugar reserves more slowly, and hopefully avoid the dreaded “bonk!”
Now that we’ve introduced the idea of developing your fat metabolism, stay tuned next week as we get into the details about how to accomplish it.

I have climbed Mt. Rainier twice now. The first time was not good. I did not finish. I had misplaced a contact lense. The second time was much better. I was a lot stronger with the second climb. It was a nice day and we all summited. It was a very nice day. I have climbed Mt. Hood and have climbed Mt Adams now. Both were nice climbs.

Those that burn more than “trace” amounts of fat while at rest or during strenuous output are fat adapted. They have gone through the process of fat adaptation by employing a lifestyle of Low Carb, Keto, etc. You don’t get there overnight and in fact some, despite their efforts, never attain it at all. And once your body becomes fat adapted, you have to maintain it too effectively utilize fat as energy. The use of a blood ketone meter is is good tool to monitor your level. That being said, the problem we face as Climbers, is how do we maintain a fat adapted state while travelling? Have you ever attempted to maintain the 75/20/5 (fat, protein, carb) ratio while in India, Pakistan, Nepal, etc? Good luck. Unless you have your food air-dropped in, or pull off the impossible and transport all of your food you will ingest over the next 4-6 weeks from home, you are stuck with noodles, rice, and junk food snacks, all high carb food, which once ingested, rocket you straight out of your fat adapted state. And back to square one. This dilemma is something i am struggling with for 2023 when i next travel to Asia. I know what i can do here on Whitney, Gorgonio and Jacinto while fat adapted and in ketosis, yes, lower elevations than Asia, but if i can some how figure out the food logistics for Asia, i will be Superman! Doesn’t look promising though.

Today was officially a rest day. Our team had different definitions of what that means but all in all we are going to bed content.
If you haven’t already guessed we had breakfast at 7:30 am, drank tea and coffee until 9 then prepared to go on a short walk. Being a lazy day, three out of the five departed by 10:15 while two others stayed back to enjoy some down time in the lodge. The weather started cloudy but improved by late morning offering new views of Makalu, the world’s fifth highest mountain and the north side of Ama Dablam which we have been viewing from its more popular side on the west.
Two members of the team hiked to a small summit at 16,600' for some extra acclimatizing while the others went back to the lodge for lunch.
Overall it was a pleasant day here in Pheriche which should set us up for our next stretch to Lobuche tomorrow.
We hope all is well back home.

The Expedition Skills Seminar - Muir September 16 - 21 led by RMI Guides Matias Francis and Seth Burns have wrapped up an excellent week of training at Camp Muir. The team enjoyed stellar weather and were able to complete their seminar training, ice climbing up to AI6+, alpine bouldering and candy bar snow protection tests (you will have to ask them) and more. The team will descend from Camp Muir today and return to Rainier BaseCamp for a final celebration. Nice work everyone!

i am scheduled to do the 4 day Rainier climb in August, 14 weeks away. Unfortunately while training i discovered a hernia and had surgery for 2 hernias 2 weeks ago. Prior to the surgery I was climbing stairs for an hour with a weighted vest and hand weights, lifting weights and cycling. I am already back to 1/2 hr climbing stairs with no problem and hiking up to 8 miles a day. I am following the Fit to climb schedule with modified core exercises until my core is strong enough. Do you think I will have a problem with this climb? I am a bit worried but feel if i continue to work hard and train smart I will be in good enough shape.
Thanks
