I’ve received a lot of ChiRunning email lately responding to my blogs about trail running. One topic that has popped up more than once is poison ivy, that nasty little plant that loves to make your skin look like an overcooked cheese pizza. I’m highly allergic to it, so I can empathize with all of you out there who spend a good part of your summer running in places other than your favorite trails, because they’re covered with the stuff. I flatly refuse to let a little toxic plant ruin my trail running so I spend a couple of hours a week covered from head to toe, in 80º heat, clearing trails near my home here in Asheville. I’ve never run in a place where poison ivy is the predominant ground cover.

Apart from resorting to clearing trails, I have found a great way to prevent the onset of a rash or to cure an infestation before it grows into a full-blown systemic case (which has happened every summer since I moved here three years ago).

Here’s what I do. When I return from a run where I know I’ve brushed up against poison ivy, I immediately throw all my running clothes in the washing machine with plenty of soap and a small amount of bleach…even my shoes! I then take a shower and pretend that I’m trying to scrub my skin off of my bones, using plenty of soap. I use a soap made from Jewel Weed which is an antidote for poison ivy, but any strong soap will work. Never take a bath after being in poison ivy or if you have an existing rash! Always take a shower.

As soon as I get out of the shower and dry off, the first thing I do is swab my legs with hydrogen peroxide to neutralize any oil residue that might still be on me. So far (knock, knock) I haven’t had a single case of it this year…and I’ve waded through plenty of it!
If I happen to get a rash (it starts of as little blisters on your skin) I immediately reach for the hydrogen peroxide, in which I soak cotton balls, and scrub the little blisters hard enough to break them. Then I repeat the hydrogen peroxide scrub about 4-5 times a day until the rash dries up and goes away. This technique has worked 100% for me and since I discovered it at the end of last summer. Since then I’ve never had a case of poison ivy last for more than about 3 days, which is completely acceptable compared to the usual 3 weeks (after a round of steroids) it used to take to get over it. So, now you don’t have to let a little poison ivy stop your summer trail running fun, you can go running in the hills to your heart’s content.
Happy trail running,
Danny

Since we’re pretty much smack in the middle of winter I’ve decided to write a blog dealing with the subject what kind of shoes to wear when running under the adverse conditions some of us die-hard outdoor runners come up against during this time of year. For those of you who live in the warmer climates… I guess you’re just going to have to vacation in the North somewhere this winter to try these out.

After spending most of my life in Boulder, Colorado I came up against probably every possible combination of winter running I can imagine. So, here’s the first installment in what I hope to someday publish as the ChiRunning cold weather running guide. For other running articles I suggest you visit the Library of articles on our website which cover many other aspects of ChiRunning and ChiWalking.

Winter running shoes. Where are they, and why haven’t the shoe companies done more to support running in snowy, cold, and wet conditions? The best thing I’ve found are Gore-tex trail shoes. These work much better than most running shoes, for a few reasons. First of all they’re wind-proof, which is a huge advantage over those mesh-toed, well-vented running shoes we wear most of the year. Secondly, they’re pretty much water-proof, unless you go into a frozen puddle that’s deeper than you think. These first two points make them warmer than your basic running shoes. I have two pairs that I use. One pair (my favorite) is made by Asics and my other pair are New Balance.

Both of these shoes work well, but they both have the same downside characteristics. Because they’re designed to be “trail” shoes, they’re stiffer and heavier than most regular running shoes. Since I wear thick wool socks for winter running, I usually buy these shoes a half size larger to make room for the bulky socks and this makes them even heavier still. I haven’t been able to do anything about the weight of the shoes, but I have altered the soles of the shoes to make them more flexible in the forefoot (which is crucial to avoiding plantar fasciitis). I take a sharp knife and cut flex grooves across the forefoot section of the sole of the shoe. Even with molded-in flex grooves, I find most trail shoes to be too thick in the forefoot to allow for enough flex. I cut the grooves deep enough to make a noticeable change in the flexibility. Everyone likes different amounts of flex, so if you do this to your shoes, start with cutting shallow grooves and work your way deeper if you need to.

For those of you who, for whatever reason, decide that Gore-tex shoes aren’t your cup of tea, I’ll write a subsequent blog dealing with how to adapt regular running shoes to winter running.

Bundle up and I’ll see you out there!

Because I’m a lifelong advocate of fitness walking and injury-free walking, I’m always trying to come up with the simplest way to get walkers to move along the ground in a way that produces the least amount of impact to the feet, knees, hips and lower back. The answer to this dilemma is different depending on whether you’re doing ChiWalking or ChiRunning. I’ll begin with you ChiWalkers.

When I watch people walk I’d conservatively estimate that over 90% of all walkers lock their leading knee as their heel touches the ground in front of them. The problem with this (and most people don’t know this) is that when your heel strikes the ground ahead of your center of mass, it creates a braking effect on your forward motion. So you’re essentially pushing yourself forward with your rear leg while you’re simultaneously stopping yourself with your leading leg. We call it “driving with the brakes on” and it’s not only an inefficient way to move down the road, but it can create long-term impact damage to your feet, knees, hips and lower back.

According to the Joint Implant and Surgery Foundation there are over 200,000 hip replacements performed in the U.S. every year! I was totally shocked at this number. Here’s a small section of an article on hip replacements that I’ve borrowed from the JISF.org website:

“Hip joint load is a function of body weight, activity level, muscular force, and the distance from the body’s center of gravity to the center of the femoral head. Publications have stated that the hip joint force increases up to 2.5 times body weight with speed in level walking.”

Let’s see… two and a half times my body weight is 290 lbs. That means that when I walk at any kind of speed on a level surface there’s a force of 290 lbs. going to each of my hip joints with every step I take. Now, if I’m reaching forward with my stride and locking my knee, that means that that same amount of force is also going into my heels (plantar fasciitis & ankle problems), my knees (300,000 total knee replacements each year according to the NIH), my hips (you’ve seen the numbers), and lower back (The U.S. spends $50 billion each year on lower back pain). You’d think that here in the 21st century we could come up with a way to prevent some of this. Well, there is something remarkably simple that you can do the next time you find yourself walking somewhere. Are you ready for this earth-shattering piece of inside information? OK, here it is….

Don’t lock your knees when you take a step forward. That’s right. It’s pretty simple. Just make sure your knees are always bent as your foot comes down onto the ground ahead of you. Here’s how you’ll be helping your hip joint specifically. When you lock your knee the impact of your footstrike travels in a direct line from your heel to your hip because all of your bones are lined up in a straight line. On the other hand, if you bend your knees, that impact is dispersed through your feet, ankles, and knees before it reaches your hip…and the resulting impact to your hip becomes almost negligible.

Of course, if you’re used to walking with your knees locked, this means a change in what is probably a longstanding habit. Remembering to do it is the hardest part, but it is much easier to do if you can remember to always work on walking with your posture well-aligned with your shoulders and head slightly forward of where you are used to carrying them. It’s just a very slight forward tilt of your upper body whenever you’re walking.

Another way to accomplish the knee bend when you walk is to shorten your stride and quicken your cadence. You’ll sense that you’re taking smaller, quicker steps, but your legs will feel very different as will the impact on your hips and knees. It might feel a bit strange at first, but if you go back and read the statistics about knee and hip replacements and think of the alternatives…you might be more willing to watch your step.

There seems to be much debate in the running community today on what is the best footstrike for running. Runners of all levels divide themselves into three basic camps: the midfoot strikers, the forefoot strikers and the heel strikers. So, here is my attempt to put forward my best understanding of the three basic types of foot strike and what each one does for a runner.

The Midfoot Strike
The midfoot strike is characterized as having your heel and the ball of your foot touching the ground simultaneously with each foot strike. You can see this very clearly when you watch young children run. They always land with their whole foot on the ground. I would say that at least 95% of all people run this way as kids.

In the ChiRunning technique, we promote the midfoot strike because it is, for most runners, the most injury-preventive way to run. Our emphasis is on preventing the lower legs (including the knees) from over-working, because this area of the body is where, conservatively speaking, 90% of all running injuries occur. Plantar fasciitis, achilles tendonitis, shin splints, calf pulls, knee pain, IT band problems, over-pronation, bunions, metatarsal and tibial stress fractures, and hammer toes lead the list of the most common running injuries. This list is immense compared to everything that can go wrong above the knees.

The propulsion in ChiRunning comes from allowing your body to fall forward with the pull of gravity, not from pushing yourself forward with your feet and legs. For this reason it is more energy-efficient because your legs are not required for propulsion. When your feet come down onto the ground, they land either under or slightly behind your center of mass, in a midfoot strike. The only work required of your legs is to provide momentary support for your body between strides. Landing on your midfoot, in most cases, either reduces or eliminates the work done by A.) the lower leg muscles…especially the shins and calves, and B.) the two tendons that are most commonly injured… the plantar tendon and the achilles tendon.

The ChiRunning technique is primarily focused on energy efficiency and injury-prevention with speed being a secondary focus.

The Forefoot Strike
The forefoot is basically the part of the foot between the forward-most part of the arch and the end of the toes… generally speaking, the balls of the feet. If your heels don’t touch the ground when you run, you’re a forefoot striker.

Sprinters, middle-distance runners, and some triathletes tend to prefer running on the forefoot because of the extra speed obtained by “paw-back” and “toeing off.” This way of running is great if you want lots of speed, but it puts the responsibility for most of the body’s propulsion squarely onto the legs…especially the lower legs. Some of the faster elite middle-distance runners (i.e. Kenyans, Moroccans, Ethiopians, Mexicans) run with a forward lean added in combination with a forefoot strike. This takes some but not all of the burden off the lower legs.

Because forefoot running is primarily used for running at faster speeds, energy efficiency tends to take a distant back seat. As far as being injury-preventive, forefoot striking helps prevent knee injuries because it lowers the impact to the knees. This is a good thing. But the problem with it is that running on the balls of your feet increases the workload on your calves, shins, achilles tendons, and plantar tendons, so you risk either overworking a muscle or pulling a tendon if you go too far or too fast while running on your forefeet.

The Heel Strike
Heel striking is when your heel strikes the ground in front of your body. At least 75% of all runners run with a heel strike. The interesting thing about this fact is that, although it is by far the most common of all the footstrike patterns, it is not done by choice, but by default. The vast majority of all runners are not elite runners or competitors, they’re just regular folks like you and me, who like to run and like to stay fit.

Most recreational runners tend to run with their body in an upright position… with no lean at all. This forces them to have to reach forward with their legs when they run…and when you run upright and reach with your legs, your feet will always land in front of your body and your heels will come down first. When you run this way, you’re basically putting on the brakes with each stride, which sends a lot of impact to your lower legs and knees. For this reason, many heel strikers complain of knee pain at some point in their running career. This is the group that keeps orthopedists and physical therapists in business.

But, just because you might be a heel striker, it doesn’t mean you’re doomed to be a heel striker for the rest of your life. Work on improving your running technique. If you can learn to run safely and efficiently, you’ll be eliminating the causes of running injuries and you won’t have to worry about ending up in a doctor’s office getting fixed.

The midfoot strike works for most runners…the forefoot strike works for some runners…but, the heel strike doesn’t seem to work well for anybody. Try all three and see which one works the best for you.

With the ChiRunning book, DVD or audio CD you can easily learn the midfoot strike. We offer you an alternative way to approach your running so that you can learn the midfoot strike and spend many more years enjoying one of the world’s best and most natural sports.

Happy trails,
