But you already knew that if you’ve been following this blog for any length of time.
Now, thanks to some researchers at the University of Exeter in the UK, I have documentation that this deadly serious vegetable is a performance-enhancing substance. In fact, there are forty pages worth of scientific documentation on just that subject in the August 6th issue of the Journal of Applied Physiology. If you’re interested.
Yes, the beet root is not only well-suited for a starring role in an offbeat Tom Robbins’ saga, but it also has important implications in mitochondrial respiration.
Deadly serious? By all means.
Do you care? Probably not.
But that’s never stopped me before. Here’s the scoop. To make a long and very convoluted story short, researchers have determined that beet root juice, which contains inorganic nitrate, decreases human oxygen requirements during sub-maximal exercise and enhances tolerance to high-intensity exercise.
So, how did they figure this out?
The researchers rounded up a compliant study group of males, aged 19-38 years old (only guys that age would agree to this). Half the group drank 500 mL per day of beet root juice, while the other half drank black currant juice, which has little nitrate content. They were hooked up to metabolic equipment to measure pulmonary gas exchange, their BP and heart rates were monitored, and capillary blood samples were collected during several days of exercise testing and juice drinking.
Well, guess what? The beet root drinkers showed significantly improved exercise tolerance and muscle oxygenation. I doubt you have to be a 19-38 year old male to benefit in this way by eating beets or drinking beet juice, but I’m happy to let them be the guinea pigs.
Ah, but here’s my take on it. Don’t wait for beet root capsules to be sold at your favorite supplement store (just wait, it will happen). Instead, eat the whole beet and enjoy it. You’ll be able to run faster and farther. Seriously.
Well, maybe it just won’t hurt as bad.
The above photo was my lunch. I sautéed onions, garlic, celery, carrots and beets in a little coconut oil for about 6-8 minutes. I added some leftover cooked brown rice and a few splashes of chicken broth and stirred occasionally for another 5 minutes or so, until rice was hot and veggies were lightly cooked.
Now I’m going to go run (maybe I’ll just walk) my dog 16% more efficiently than if I hadn’t eaten beets. That might be a bit of a leap, but you get the idea.
Eat all your wholesome CSA or Farmer’s Market power food and you’ll be dancin’ in the streets like this guy.
I’d suggest you tell your kids that if they eat their veggies they’ll be able to do stuff like this — but then again, it might happen and you’d be stuck with a kid who does stuff like this. Yikes!
Go forth and eat your power veggies. Stay tuned, I’ll post a “hearty greens” recipe tomorrow. This one’s just for fun.

I’m shifting from food to altitude to sophisticated blog posting from the highest mountain on the planet. First a short altitude 101 lesson to create the appropriate ambiance (pun intended).
I took the above winter mountaineering photo from the summit of Drift Peak, high in the Tenmile Range of the Colorado Rockies. Drift Peak is a little over 13,900 feet, making it one of Colorado’s centennial peaks (the 100 highest summits, all over 13,800 feet in elevation).
If you’ve ever wandered around at high altitudes (above 10,000 feet), you know that as you ascend it becomes more and more difficult to do anything in a hurry. Your legs feel heavier, your respiration increases and you might even feel nauseous or develop a headache. That’s because you’re not breathing in enough oxygen and the consequences can go from mildly annoying to life threatening.
I won’t go into too much detail, but the higher you go, the more the body has to adapt to less air pressure, therefore less oxygen intake. Here’s where it gets confusing. The percentage of oxygen in the air is the same whether you’re at sea level or on top of Mt. Everest, which is 29,000 feet. Our atmosphere is made up of 21% oxygen at any altitude. There isn’t less oxygen as a percentage of gases at 29,000 feet, it’s just that the higher you go, the less atmospheric pressure there is. With less air pressure the oxygen molecules scatter into a larger volume of air. If I’m standing at sea level that same 21% of oxygen molecules is being pressed down around me so it’s much easier to breathe and get the oxygen I need to do whatever it is I’m doing.
Our bodies do adjust somewhat and depending on our individual physiology, we adapt and acclimatize to varying degrees. To begin with, our breathing increases and our movement slows down. Heavy breathing (the altitude-related kind) allows us to take in more oxygen and get rid of carbon dioxide. Our heart rate goes up to deliver the oxygen to our brain and muscle tissues. There’s also a lot going on with our kidneys when we increase elevation. Have you ever noticed that as you get above treeline you have to go to the bathroom more often? Darn, no bushes to hide behind — that can get a bit tricky if you’re a girl (especially in the winter). Men have it made.
Here’s what happens (to make a long, complicated story short). Your kidneys know you need more oxygen so they conspire to get rid of extra water so your blood becomes thicker and can carry more concentrated oxygen. Aren’t we just amazing little creatures?! All the more reason to honor our bodies and take care of ourselves.
I’ll leave it at that and get on to the point of this post, which is about dispatch-blogging at super-high altitudes. I just wanted to set the stage as I often find it difficult to write a wimpy little post while sitting in my office, listening to music and sipping tea. Think about doing it on Everest. It’s hard enough just to breath, let alone create glorious dispatches such as these.
I’m a Mac girl, so I love the idea that they’re using MacBook Pros to do their Himalayan blogging. I’ve been following the progress of this expedition and their daily dispatches since they started several weeks ago. I’ll explain why later and keep you posted as the team expects to summit in a few days.
I took these photos at the base of Winter Park Ski Area in the mountains of Colorado. No thought went into it, no positioning myself for optimal light, no effort to get the right angle. I had my little point and shoot camera in my jacket pocket and as I was taking my skis off to go inside and eat lunch, I saw this wonderful dog on duty. Although he was doing his dog job, he was also taking full measure of the fact that his owner was off tearing up the slopes and he could take a break and relax in the sunshine.
Whoever owns this dog skis at Winter Park and if his (or her) wheelchair is any indication, he (or she) is out and about regardless of what some might call a “limitation.” Winter Park is home to the National Sports Center for the Disabled and is known internationally for the caliber and dedication of its athletes and participants. That includes the hundreds of volunteers who are committed to helping people with disabilities learn to ski, snowboard, snowshoe, climb and enjoy the outdoors. The program also includes the Disabled Competition Center and the NSCD Alpine Ski Team. The Competition Program has placed dozens of racers on the U.S. Disabled Ski Team. At the 2006 Paralympics in Turin, Italy, NSCD worked and trained 16 of the athletes who were representing the USDST.
Miles from England and Xenny from South Africa inspired me to do this post (although they don’t know it). Long story, but Xenny is an amputee and plays on the beaches in South Africa. When I saw a photo of “Xenny’s Beach” on Miles’ blog and read how newly installed stairs gave Xenny access to the beach, it made me smile and think of my own stomping grounds. I’ve spent my life skiing at Winter Park (and Mary Jane) and the base area is home to wheelchairs, artificial limbs, and the occasional dog companion. The scene always inspires me.
Do you ever talk yourself out of doing something because you think it will be too much effort? Convince yourself you don’t quite feel good enough? No real reason, you just can’t seem to muster up what it takes to get off your bum and go move about? We all do that on occasion. I did it yesterday and skipped one of my favorite yoga classes because I was — lazy?
Okay, no excuses.
Imagine what it must take for this guy (or girl) to get up skiing. Or the access needed for Xenny to get to the beach and have fun. I’m grateful to have these folks around for inspiration and I thank them from the bottom of my whiny (occasionally) little heart.
If you need more inspiration in the coming year to celebrate life and movement, check out this video of one of my all-time yoga heros, Matthew Sanford.
Tell me, what is it you plan to do with your one wild and precious life? — Mary Oliver
I definitely plan to finish the second half of the Colorado Trail. That is at the top of my “things I absolutely HAVE to do during my one wild and precious life” list. Hopefully I can finish it next summer as work and family responsibilities have put completion of our journey on hold for now. My son and I recently finished the first half of the CT — from Denver to a trailhead between Buena Vista and Salida. We backpacked close to 250 miles and trudged up (and also down) some 37,000 feet of elevation gain.
That’s a lot of ups and downs. In a variety of ways and for a variety of reasons. Our trek took us through four different wilderness areas and over several mountain ranges. In addition to a variety of terrain, we experienced all kinds of weather as well — including sun, rain, sleet, hail, and even snow. We also inadvertently timed our travel through the Mt. Massive Wilderness area during the Leadville 100 Mountain Bike Race and ended up having to spend the night at a hotel in Leadville (aaahhh, nothing like a warm shower and a soft bed). Lance Armstrong competed in the event, which is intense to say the least. It’s a 100 mile off-road mountain bike race with what is described as “steep climbs and serious descents.” No kidding! The start and finish is in the heart of the small mountain town of Leadville, CO (elevation 10,200 feet). Fifty miles out and back with a turnaround point at 12,600 feet makes this race pretty dang extreme. After 100 miles, Lance was second by less than 2 minutes! How does that happen? Two minutes after 100 miles of mountain bike racing? And there were hundreds of entrants.
There’s also a Leadville 100 Ultra Marathon which is billed as the “Race Across The Sky” and considered one of the toughest distance races on the planet. It was held the following weekend. Starting at 4 AM, with most of it on the Colorado Trail and the Continental Divide Trail, it’s a true high-altitude, hard-core distance race. To make it even more interesting, this year runners experienced rain, wind, lightning, marble-sized hail, and snow during their 100 mile marathon. Almost sixty percent of the entrants didn’t finish. They’ve been doing this race for 26 years now and they never cancel because of the weather. Hardy souls indeed.
But I digress…
We experienced some of the same weather during our journey, but at least we were in our sleeping bags and tents at 4 in the morning and we didn’t have to cover more than about 12 to 15 miles a day. Some longer days, some shorter days.
Spending that much time in the wilderness allows for hours and hours of time to think, reflect, figure things out, day-dream, re-figure things out, make up endings to stories, sing Johnny Cash songs, wonder what that noise was, think about food, learn to whistle, re-re-figure things out, and have long annoying conversations with yourself. And on it goes, day after day. No money to deal with, no bills to pay, no TV to watch, no phone to answer, no email to check, no newspaper to read, no gas to pump, no purse to dig through, no mirror to look into, no BlackBerry to obsess over (not that I have one). Going back to the basics is incredibly cleansing. I highly recommend it.
Now I’m in the midst of putting together my backpacking meal recipes, sport-specific nutrition information, dehydration tips, and instructions on how to prepare and pack your own food for the backcountry. Most prepackaged backpacking foods contain gluten or other allergens and most companies can’t guarantee that their food is gluten-free, even when there are no obvious gluten-containing ingredients. Most of those foods either use gluten as a filler or prepare their foods on equipment that also processes foods containing gluten. The last thing I want is to get sick while backpacking. No time to have stomach issues. Or achy joints. Or be overly tired. Or have trouble sleeping. Or have headaches.
Well, you get the idea. That’s why I felt it was important to make and prepare all my own food. That way I was able to balance my nutritional needs for exactly what I was doing — this means eating strategies for all-day energy, what to eat when you need a boost to make it up and over the pass, and how to adequately recover so you can start all over again the next day. I’m interested in sport-specific nutrition and how to maximize performance and stay healthy at the same time. I’m thinking a book is in my future. Wish me luck.
In the meantime, here’s a photo wrap-up of our trip, with a reader contest to top it off.
Next week I’ll get back to regular posting with nutrition tips, recipes, and whatever else comes to mind. Does anyone have a topic they’d like me to focus on? Something you might be confused about or interested in? Leave me a comment indicating what’s on your mind and I’ll pick one of the topics and write a specialized post on it.
Photo #1 — Melissa filtering water (a wilderness woman’s job is never done).
Photo #2 — Columbine, the Colorado state flower.
Photo #3 — Breckenridge Ski Area way in the distance.
Photo #1 — I became obsessed with taking pictures of signs along the trail. Some were interesting, some informative, some just plain funny. These little “thumbnail” versions of my photos aren’t great, so I doubt you can see this very well, but it says, “Colorado Trail & Tennessee Pass” with an arrow one direction, then it says “Old Mine” with an arrow the other direction. Who knows where the old mine is as we had just come from that direction and never saw one. Hmmm?
Photo #2 — Very old CT sign, with an awe inspiring back-drop.
Photo #3 — Big mountains.
Does anyone know what this is? Keep in mind, this “find” was out in the middle of nowhere along the Colorado Trail. The first person who knows the answer gets a prize. Take a guess!
And don’t forget to get out there and enjoy your one wild and precious life!
One-hundred and sixty miles down. Three-hundred and forty to go.
We’re one-third of the way through our trek of the Colorado Trail. Depending on what you read, the trail covers anywhere from 485 to 500 miles — from Denver to Durango — with a total elevation climb of 77,690 feet. As I said in the first post I did on the Colorado Trail, that’s a LOT of uphill. We’re now on a 200 mile section of the CT that shares the same footpath as the Continental Divide Trail, so we’re spending more and more time above 10,000 feet, often in alpine zones above timberline.
I’m cooking and dehydrating all our dinners and we’re eating well. And gluten-free, of course. In fact, I have chicken, quinoa noodle, and veggie soup in the dehydrator as I type. With chile con carne waiting in the wings.
Rather than ramble on about the trip, I’ll share some photos with you instead. I’m in a pinch for time, but when things slow down, I’ll get back to posting on a more regular basis. For now, here’s a preview of where I’m spending so much of my time lately. Although the days are long and tiring, there’s nothing more rejuvenating than spending time in the wilderness. No phones, no money, no traffic, no silly TV shows. I love it!
If that waterfall hadn’t been so dang cold, I would have taken a shower — with all my clothes on. They needed washing as much as I did. I won’t even mention how my hair looks after a week of backpacking, although bad hair days aren’t a big deal when all you see during the day is your hiking partner, a few marmots, and a couple of deer.
