Between training and the climb itself, climbers spend a lot of time with a pack on their backs. Somewhat of a necessary evil, the goal is to make your pack carry comfortably and efficiently so that it doesn’t work against you. A few tips that will result in a more enjoyable pack to carry:

1. Minimize dead space in the pack

2. Try to fit everything (except the ice axe) inside the pack

3. Keep the mass of the pack close to your body

4. Frequently adjust the straps to carry the load more comfortably

5. Have a system 

Minimizing dead space in the pack will help the pack ride in a more balanced way, and allow you to fit everything inside. A big factor that creates dead space is too many stuff sacks packed together. Round or barrel shaped stuff sacks don’t nest together well, instead leaving large gaps between them (like a cup full of marbles). To minimize this effect, try to limit the number of stuff sacks you use. A compression stuff sack for your sleeping bag is important, as it dramatically reduces the volume of the sleeping bag, but most of the other items can be packed loose, without stuff sacks. The down parka and spare insulating layers do a great job of packing around the sleeping bag to fill any spaces. Some guides go so far as to pack their pack partway, and then (taking care not to crush anything breakable) insert their foot into the pack and squish everything down to squeeze out all of the air. In addition, if climbers have packs with dedicated sleeping bag compartments, I often recommend that they detach the shelf that separates the compartment from the main pack, and treat the pack as one large tube. Sleeping bag compartments tend to create dead space where we want it least, right near the center of mass of our bodies.

Minimize the number of items that are attached to the outside of the pack. The ice axe generally has a dedicated attachment point (the ice axe loops), and is really the only exception to this rule. The rest of our equipment should fit inside the pack. With a little bit of thought, items that seem to take up a lot of space can be packed more efficiently. For example, by stuffing the helmet with extra socks and food before packing it, the volume of the helmet itself becomes very little. Crampons can be put together so that the tines cover each other, and they too can be placed in the pack. Items clipped to the outside of the pack tend to swing, get damaged, and make a ruckus. By minimizing the number of items clipped to the outside of the pack, your pack will carry more comfortably and with less noise!

In general when you are packing, place items that you won’t need or use that stretch to the bottom of the pack, while items that you would like to keep handy (food, sunscreen, etc) stay near the top. Additionally, place heavier items closer to the back panel of the pack, keeping them nearer your center of mass.

There is no perfect fit for a pack, and comfort and fit of your pack will change throughout the course of a climb or training session. In general, try to carry the majority of the weight on your hips. When putting on a pack, hitch the pack up higher on your back than it will ride, and cinch down the waist strap. Then tighten the shoulder straps until they just make contact with your shoulders. Next, lightly tighten the load lifter straps on the shoulder straps and waist belt. This helps to pull the weight of the pack in closer to your back and helps with balance. Lastly, constantly adjust throughout the day as discomforts arise!

Have a system to your pack so that you have a good idea where each item is. This will save you time and frustration throughout the climb, if you can reach straight to a warmer pair of gloves for example, rather than unpack most of your pack each time you need an item. With a well-organized system, you will spend more time at each break resting and recovering, and less time digging for items in your pack. With a little bit of time and practice your pack won’t be such a burden and your training sessions, and ultimately the climb, will be more enjoyable!

One of the unique aspects of a Denali climb is that it is one of the few big mountain climbs in the world where you can’t hire someone to carry some of your gear. There are no porters, donkeys, yaks, or other pack animals. This means that once the plane drops us off at Kahiltna Base Camp at 7,600’, we have to find a way to move three weeks worth of expedition provisions and our gear up the glacier, and this necessitates each climber pulling a sled.

The use of sleds is unique to Denali and Vinson Massif, and is a component of the expedition that we often overlook when we are preparing. On Denali, we typically use sleds to 11,000’, or for the first 3-4 days. While this is a small component of the expedition, those first few days can leave climbers feeling exhausted and depleted, with the bulk of the climb still to come. Spending some time training with a sled in the lead up to an expedition could help ease this.

On the mountain, we use plastic expedition sleds, not unlike a kid’s sled that you might find at a hardware store, but with a bit more length for added volume and stability. A typical climber has between 40 and 50 pounds in their sled at the outset, and we rig the front of the sled with a trace that clips to a single loop of webbing tied around the climbers backpack, preferably threading through the slot that houses the hip belt, so that the load pulls from low on the pack, about even with the hip belt. This transmits the climber’s pull most efficiently, and keeps the climber in a more efficient alignment, pulling from the center of mass.

To prepare for sleds, try pulling a mock sled during a handful of your endurance workouts (over an hour or so) in the few months leading up to the expedition. Climbing with the sled behind you not only recruits different muscles and requires strength in different areas than climbing without, but requires that we alter some of our movement patterns a bit to remain efficient. The biggest pattern to change is the bread and butter of the mountaineer: the rest step. Efficient movement with a sled involves keeping the sled moving forward steadily. Each time it stops, we have to overcome inertia to get it moving forward again. Therefore, we want to keep our hips moving forward steadily (which is a change from the rest step). We can still get some rest in our legs with each step, by locking out the back leg as we step forward, moving that leg under our hips. Using the resistance of the sled for balance, we can allow our hips to slowly travel over our back leg toward the front, while still maintaining the moment of rest on the back leg. As the hips arrive over the front leg, step up and repeat.

Climbers have found a number of sled type devices to train with; the two most common are a car tire and a plastic sled loaded with some sort of weight (even the kids!). Plastic sleds slide on grass pretty well, while the car tire doesn’t slide as well and tends to add more resistance. Using the mock sled during some of your endurance workouts is most similar to what we’ll experience while climbing, but pulling a sled during an interval workout is also a creative way to add resistance and effort. Happy hauling!

From RMI Guide Hannah Smith: The Mt. Rainier summit is not guaranteed but the rising sun is. Gusty winds made for a high point at Ingraham Flats- short of the summit but still challenging.  Our team is packing up and heading downhill shortly.

It was another breathless, warm morning on the Ecuadorian countryside. Our beautiful hacienda was situated perfectly in a giant valley which runs directly from our dining room window unabated for 7000’ vertical feet straight to the summit.   

Chimborazo, the farthest point from the center of the earth and closest to the sun, was mostly displaying her majesty as we sipped coffee and ate our eggs. As the morning wore on, she hid herself from view and we loaded the magic bus ready to take us to the Chimborazo trailhead.  By 1:30 all our packs were packed, and it was off to high camp at 17,500 feet.

At this altitude nothing feels perfect, unzipping your trousers just to take a pee can leave you winded. But our seemingly invincible team has again handled things with grace under pressure and is doing well up here.   Once again, the Ecuadorians have done it right, providing a giant dome tent for our lounging pleasure.

But don’t get too comfy bloglandia, the alarm is set for a mere four hour from not.  It is then we will have our final test?  

The is rest well with a positive psych ! Wish us well!
