What Do Running Shoes Actually Do?

In his blog post, Looking at Pronation, Cushioning, Motion Control and Barefoot Running, Steve Magness challenges some strongly-rooted assumptions about the benefits of running shoes and puts forth his opinion that the current categories used for running shoes -- cushioning, neutral, stability, and motion control -- should be rethought and replaced based on what really happens in a runner's stride.

Magness surveys several research studies that tried to look at the real relationship between impact forces, shoe correction, and injuries. The thing that struck me the most was Magness' contention that shoes, or at least the wrong shoes, interfere with the body's natural adaptation to forces.

The human body is an incredible organism. Judaism and Christianity have long acknowledged that fact. The writer of Psalms said: ...I am fearfully and wonderfully made... (Psalm 139:14, NIV)

Science agrees and Magness affirms that viewpoint:

we underestimate the human body! It’s an amazing thing, and we never give it the credit it deserves. The body adapts to the surface that it’s going to strike, if you give it a chance. The body adapts to both shoe and surface adjusting impact forces via changes joint stiffness, the way the foot strikes, and a concept called muscle tuning.

My take-away from the article? For now, at least, I have no intention of giving up my running shoes. Though I love going barefoot*, I've worn shoes while walking and running for 55+ years and suspect that my feet have adapted, for better or for worse. Besides, they are definitely not tough enough for Nairobi roads. However, I think I'll work on mimicking the style of running that the body seems to naturally use when running barefoot -- attempting to ensure footstrike beneath my body's center of gravity rather than out in front, shortening my stride length, and increasing my turnover rate.

Provocative article. What do you think? Would a change in your stride or you shoes make a difference in your running?

Run well, y'all,
Bob

*...barefoot... -- I like the dress code for my current office. Since I office in my house, I can and do go barefoot a lot. It's great. TCK's (third culture kids) in Africa are notorious for going barefoot whenever and wherever possible -- I'm not one but in that respect, I'd make a great TCK! :-D

Getting Back on Track

Well, if I run in the morning, I will have run about as much this week as in all of December. And, based on the last 4-5 years of running, this week has been a short mileage week.

The runs have been relatively short and slow, but I've been out there and building back my mileage:

Monday: 2.9 miles Pace: 9.43 mpm
Thurs: 4.1 miles Pace: 9.37 mpm
Friday: 3.3 miles Pace: 9.28 mpm
Saturday: Planning on 4 miles

I'm glad to be back on the road.

Run well, y'all,
Bob

Look, Ma -- No Wires!

This has nothing to do with running but it's fascinating stuff.

My wife and I have said, many times, how much we wish someone would come up with a way to recharge stuff without having to have wires running everywhere. It's moved from Sci-Fi to real life. I had seen the PowerMat charging system for cell phones, etc, but the technology is moving ahead very quickly. The following was in a report of the CES (Consumer Electronics Show) from TidBITS (#1009, 11-Jan-10)

Finally, we come to the blender. It was a perfectly ordinary blender, sitting on a black box. It whirred like all blenders do. Then I noticed that there were no wires attached to the blender. It ran, like the toaster that sat next to it, on inductive power. There have been inductive power pads around for a while for charging low-power devices like cell phones, but blenders and toasters are orders of magnitude more thirsty for electricity.

The magic in the black box comes courtesy of Fulton Innovation's eCoupled technology, which uses magnetic induction to create a current in receiving devices. eCoupled electronics communicate with the black box to tell it how much power it needs. Electronic devices within range of the box which do not communicate with it are somehow left out of the induction field. When I expressed concern that other devices would burst into flames while the wireless power was active, the presenter turned on the blender, put his cell phone down next to it, and offered to let me make a call.

I can't say that I have an engineer's understanding of electricity, but I was under the impression that magnetic induction is an all-or-nothing sort of thing. Fulton has apparently managed to create a power supply which can feed kilowatts to intelligent devices, without affecting other electronics within range. I think he probably could have cloned a cat, á la Nikola Tesla in "The Prestige," and I wouldn't have been any more surprised by the demo.

Common implementation of ubiquitous wireless power would completely change our relationship with technology. Picture a laptop with a battery that never runs down, because it's constantly being charged. There isn't a single electrical device that couldn't benefit from this technology, and many would be transformed by it.

I can't say whether Fulton will be the company that succeeds in bringing inductive charging to the mass market, but it was immediately clear to me that this technology is the future.

Here are some web links to additional information. The Wikipedia article on inductive charging talks about the development of proximity transmission of electricity (versus the device having to actually be in contact with the power source as is the case with the Powermat and the above blender):

eCoupled Wireless Housing
Powermat
Wikipedia Article on Inductive (wireless) Charging
Wikipedia Article on Wireless Energy Transfer

The techie/gadget-loving/geeky side of me sort of wishes I had gotten the Powermat. :-D This is really cool.

Clawing My Way Back

One of my reoccurring dreams has to do with running. I wish it was about running with some of the great East African runners and feeling good. But, it's usually an exhausting dream where I'm trying to run up a long, steep hill that's usually deep sand. Instead of running, I'm barely moving forward, digging my hands into the sand and pulling myself uphill.

Well, I think that's how my running is going to feel for the next couple of months. Due to a variety of reasons (travel, an odd injury, boredom with my routes, a cold), I've only run 6 times since 21 November with this morning's run being the first in 3 weeks. I'm not completely starting over but at 55 years old, I think I lose fitness more quickly than ever and it will take me longer to get it back. But, I'm committed to getting it back.

My goals:
• Get back to 100+ miles per month
• Run a half marathon in Nairobi in October
• Lose 20 pounds

There I've said it -- here goes. This morning's run was only 2.94 miles at a pace of 9:42 mpm -- SSD (short, slow distance). I'll bump up my mileage slowly and see what happens.

Have you ever come back from a running slump? Any advice?

Cost of Running: Shoes

the Ringmaster, who blogs at Mile by Mile, posted an interesting blog the other day. She talked about the shoes she had used during 2009 and had figured out her cost per mile for shoes. As much as I like numbers, that is one calculation I hadn't done.

So, I went back and ran the numbers for all the shoes for which I've tracked miles over the last 3+ years. Interesting. In that time I've run in and retired 6 pair of running shoes. I currently have 2 active pair. My average cost per mile was $0.134 per mile. Some other stats that caught my attention:

Most expensive: Brooks Adrenaline GTS7 (2007)

$99.75, 454 miles - $0.22/mi

Least expensive: Etonic Jepara SC 1 (2008)

$72.00, 714.4 miles - $0.10/mi

Longest lasting: Etonic Jepara SC 2 (2008)

$93.00, 817.7 miles - $0.11/mi

During 2009, I used 4 pair of running shoes. One pair, Brooks Adrenaline ASR, was a pair that I bought at the end of 2005 for cold, wet runs. When Richmond, VA had 9+ inches of snow in March 2009, I dug out these shoes for 2 or 3 runs to keep my feet as warm and dry as possible. I would not have wanted to run on dry pavement or for very far with those shoes as they were worn out -- but, they kept me drier than other shoes would have done.

I wore out a pair of Etonic Jepara SC 2's that I had started wearing at the end of Oct 2008. I used those until June 2009 and had 817.7 miles on them. Then I started using a pair of Etonic Jepara SC 1's. When the rainy season started in Kenya in October, the SC 1's became my mud-run shoes and I added in a pair of Etonic Jepara SC 2's for drier runs. The SC 1's now have 504.6 miles and the SC 2's have a measly 62 miles.

Enough stats for now.

Follow the Footprints

Living in another culture can be so interesting. Just before Christmas our daughter came home to spend Christmas with us in Kenya. I was in the US for a meeting when she arrived and before I returned, my wife and Stacey drove to the Kenya coast to visit some friends before we took a few days of vacation on the Indian Ocean coast. When I returned, I flew to Mombasa to meet up with them.

When I arrived at the Mombasa airport (Moi International Airport), we deplaned on the tarmac. As we headed to the terminal, the airport employee who was directing us told us to just follow the footprints and we would get to the right place. Sure enough....It was funny but effective.

Hmmmm. Life lesson here. If you follow the right footprints, you end up in the right place. Whose footprints are you following? (Joshua 24:15)

Why Do They Call It a "Dashboard"?

Earlier today, a co-worker was explaining a new online process for our personnel to use in accessing and tracking budget information. The new finance program, FE, uses an online dashboard. This co-worker did an excellent job of explaining how to use the process but then posed the question, Why do they call it a dashboard? I wish I knew. He quoted the definition from Wikipedia which only referenced the Dashboard module of the Macintosh operating system (OS X). Since I had struggled with the concept, I thought I might be of some help.

He said it helped him. So, perhaps, though not running related, this will help someone else. Here's my response to him:

More, I'm sure, than you want to know -- way more -- but when I saw the trailer on your note [his question and the Wikipedia definition], my geek side kicked in. This is a layman's understanding and may not be a technical explanation:

"Dashboard" was a confusing term when I first encountered it in computer usage. It helped me to think about the dashboard in a vehicle. It contains gauges or lights that give the driver information about the state of the vehicle -- speed, miles, RPM's, heat, fuel remaining. Newer or more expensive vehicles give even more information -- my daughter's Civic tells her when to change her oil; my mother-in-law's Buick shows her the air pressure in her tires and real time MPG. The dashboard also contains some "items" that are interactive, allowing the driver to control various aspects of the vehicle -- cruise control buttons, audio system controls, HVAC controls, One Star controls, etc.

In computer terms, dashboard is used in the same sense and it's used in a lot more instances than just the Mac OS X. For instance, web hosting sites use the term dashboard or control panel to talk about a web page where a user goes to get information about or to manage his/her account. The page will most often display icons that link to pages relating to various aspects of ones accounts. For instance, for the [regional] web site, my dashboard/control panel shows how much of my allotted disk space I've used, how many e-mail accounts I've set up, and icons for setting up e-mail accounts, setting up automatic forwarding, managing FTP sites, controlling filtering, managing files on the server, etc.

Every person who has a gmail account has a Google dashboard, that gives the user information about the overall account and allows him or her to manage settings for various accounts (Gmail, Calendar, Analytics, Blogger, Picasa Web Albums, Web History, etc.) under their Google account umbrella. Those who have a Blogger account (another Google "service") have a dashboard that shows all the blogs that one is managing and allows one to customize the appearance of the blog, manage settings, post/edit blog entries, etc.

In the Mac OS X, the dashboard is the virtual desktop that, when activated, shows mini-programs (widgets) that do various things. Though I can't recall the term that Microsoft uses, Vista has a similar functionality with some differences in implementation. On my Mac laptop, I have a bunch of those widgets installed: a program that shows the status of my battery, one that shows the status of my network connections and the heat output of various components of my laptop, one that gives baseball scores and division standings, one that shows the weather, one that shows keyboard shortcuts, one that will compute my running pace, etc. So, the concept is the same as Google or web hosting dashboards -- the dashboard contains programs that either give information or allow the user to manage various aspects of the computer.

Sounds like FE has adopted that usage of the term, dashboard. The dashboard is where the user gets information and manages, in this case, reports related to his/her finance account with the company.

Ahh. Forgive me. Now back to real work. :-D

There you have it. I hope that's helpful to someone. Now I really do need to get back to real work. I'd rather be running.

Bob

Everyday Traffic in Nairobi

Great blog post from a Daily Nation (Nairobi) writer. This kind of traffic is not an occasional thing but an everyday occurrence. It starts about about 6:30 AM and continues until 9:00 PM or later. The only day it's not like this is Sunday. Now showing on Nairobi roads

Because of the crazy traffic, I have to run at 6:00 AM or put my life at the mercy of some of these people.

Running Is Good for Your Back

(DISCLAIMER: I'm reporting a study and my own experience. I'm not a doctor, physical therapist, certified coach, or anything other than an amateur runner.)

I don't have major back trouble. Several times in my life, I've misused or overstressed muscles in my lower back and have been down for a day or two. And, I have a small twinge in my lower back from time to time. Over the last 6+ years of running, though, I have experienced that I have much less trouble with my back when I run than when I don't. In fact, in those 6+ years of running, I have not had a single incident of my back going out. I also know that my twinge is much less likely to appear on the days I run than on days I don't run. A lot of that is probably attributable to the fact that I'm many pounds lighter than in my pre-running days.

Runner's World's Peak Performance reported on a study that showed that running is an efficient exercise for backs. So, there is a study that corroborates my experience. It's good to know that I have been doing something good for my back as well as my heart, lungs, and waist.

Here's the link to the actual study report:

Trunk muscle activation during moderate- and high-... [Appl Physiol Nutr Metab. 2009] - PubMed result

All that being said, though, December has been a wash for me as far as running. I had some upper thigh issues around Thanksgiving and took 8 days off. Then, when I ran again, I was extra sore. Add in the rains, a trip to the US, vacation here, and now a cold -- I could count on one hand the number of runs I've had in this month. That will change -- not only do I like to run but I like to eat. :-D

Run well, y'all,
Bob

Stinky Shoes

Ashland Dave talked about stinky shoes in his podcast of 26 September 2009 -- it was somewhere in the first 15 minutes of the podcast:

Running in the Center of the Universe

Stinky shoes are a real problem for me. I am a profuse sweater, so my shoes are always pretty soggy when I finish a run. They are relegated to a place on the porch when I finish running. They do all right until...

...until I run in the rain. For some reason, that seems to push them over the edge. Even though I take out the insoles and stuff the shoes with newspaper to get them to dry, getting them soaked that way seems to bring out the smell and make it permanent. I can wash them and, while it helps, they still stink. I've tried to spray them with Fabreeze and that works until I run again.

Any ideas would be greatly appreciated. Until I find a solution, though, Shoes, you stay outside!

Run well, y'all,

Runner-Friendly or Unfriendly?

While I'm sure there's more to the story than this particular take on it, Portsmouth, NH doesn't sound like a runner-friendly place to run RW Daily: Portsmouth to Runner: Drop Dead!

As I read the story, I was reminded of how fortunate I was to have lived in the Far West End of Richmond, VA for 4.5 years. Not only are there a lot of friendly runners there, it's definitely a runner-friendly place -- wide streets and courteous drivers. I only recall two aggressive drivers and they had probably just had a bad day. I did have to dodge a couple of school buses. Nothing like Portsmouth, NH.

Exercise Prepares Our Bodies for Stressful Situations, Study Indicates - Mind Hacks - Lifehacker

Interesting. We runners knew this, naturally. After a long run, we're so stress-free that nothing fazes us except having to move out of the recliner.

Of course, one logical conclusion from this study would be that running only makes you calmer when you get dunked in cold water -- if, that is, you're a running rat.

Exercise Prepares Our Bodies for Stressful Situations, Study Indicates - Mind Hacks - Lifehacker

I'm taking a few days off from running -- 8-10 days. I have some fairly minor aches and pains and just don't have the want to that I've had. This will be the first planned break in 6.5 years.

Key Factors in My Running

I took off this morning intending to do 5.5+ miles. For some reason, I just couldn't do it and ended up cutting it short a bit. Lately, more often than not, my runs have just been hard. I think I have to face the facts.

OK, yes, I'm running at altitude (5500'+) and every run is hilly (there's just no flat run here). But, I'm also running more slowly than I did at sea level -- 8:00-8:30 at sea level, 8:30-9:05 at altitude -- so I shouldn't feel completely wiped out. Also, I'm bored with my routes -- without driving somewhere else in town (which I'm loathe to do), my options are limited. I'm used to the 300+ routes/variations I had access to in Richmond.

But, I think there are two factors that are probably more important than those -- weight and base mileage. Basically, I'm 12 pounds +/- heavier than when I was running my best. So, I just need to get rid of it. Secondly, and maybe even more importantly, my mileage has slipped. Rather than running 30-35 miles per week (or even more when getting ready for a race), I'm running 15-20 miles per week. That means a 5 mile run is 25-33% of my weekly mileage now but was only 14-17% 6-12 months ago.

So, I think I have some work to do.

Run well, y'all,
Bob

RW Daily: One Gift You Don't Want to Unwrap

For all of you runners who have wondered what to give your family and friends for Christmas, check out this Runner's World article. Somehow, I don't think my family or friends would have much appreciation for my race picture on a mug.

For the West End (Richmond) Runners

This post is dedicated to my friends and running pals who ran the Suntrust Richmond Marathon and the McDonalds Half Marathon yesterday. You are my heroes -- I saw some good times in the results. Maybe these thoughts from Meb will resonate with you:



(Stolen from Half Fast who stole it from Running is Funny who stole it from ...?)

The words for the week are: rest, recover, refuel. Then enjoy running.

I got in my longest run to date in Kenya -- headed out after our worship service for a slow (relative, I know) 6.38 miles in 58:21. With the altitude and the hills, I figure that ain't too bad.

Run well, y'all,

Our "Home" City, 2005-2009

This is a shout out to my homies in Richmond -- John Rolfe 10K Training Team, John Rolfe Patrick Henry Half Marathon Training Team, Posse running group -- many of whom are running either the Richmond Marathon, Half Marathon, or 8K next weekend. Good luck -- you all are so ready for this. (Don't worry -- that's the end of my attempts at urban language.)

From May 2008 until July 2009, we lived in Richmond, VA. While we would have preferred to have been overseas, Richmond was a good place to live and a great place to run. This video gives an overview of some of the reasons for that (we didn't do all that's rapped about in the video) -- and it's a fun look at the city.

It's No Wonder...

It's no wonder that weight has become such a problem in the US among most age groups -- 34% of US adults over age 20. (See state-by-state trends here.) Browse through this selection of tempting desserts offered at American restaurants. Who would think that one could consume such huge quantities of calories, fat, sugar, and sodium in a single serving of anything!

Slideshow: 15 Worst Desserts | Eat This, Not That

(Note: This is not, by any stretch of the imagination, an endorsement of Men's Health magazine.)

Note that the better recommendations in the slideshow are not particularly healthy, but they are less bad than the worst offenders.

Those of us who run or engage in other types of strenuous exercise must be very careful to avoid the fallacious thinking that because I run, I can eat whatever I want. If I'm maintaining my weight with my normal amount of eating and current level of running miles, it would take an additional half marathon -- actually 13.28 miles to counter the calories contained in Romano’s Macaroni Grill New York Cheesecake with Caramel Fudge Sauce (1660 calories -- more than 3 Big Macs -- and the saturated fat equivalent of 57 strips of bacon).

A huge part of who you are physically (pun intended) is what you eat.

Off to run 5 miles or so.

Kenyans in America and an American in Kenya

I've swapped places with Kenyan runners, Robert Cheruiyot and James Kwambai. Well, OK, that's a bit of hyperbole but they were in the US for the NYC Marathon and I've returned to Kenya, though certainly not to run a marathon.

The following is an interesting article on the final week of preparation by Cheruiyot and Kwambai for the NYC Marathon:

How the Kenyans Take On New York

It's interesting from a runner's perspective but also because of some of the cultural tidbits like this:

Later, at a buffet breakfast at the hotel...both drank hot tea with milk, and Kwambai poured in packet after packet of sugar, as if building a sand castle in his cup.

Chai -- hot tea, usually cooked in half mile and half water and with lots of sugar, is the national drink of Kenya. Every Kenyan I know, except those who are battling diabetes, puts tons and tons of sugar in their chai. Yet, most Kenyans don't like desserts because they are too sweet. Go figure. Those kinds of anomalies always make me wonder what kind of quirks we Americans have in our culture -- I'm absolutely sure there are many.

Enjoy the article.

I'm back in Kenya after a couple of weeks in Richmond for meetings. I enjoyed the boost of going from high altitude to sea level but now am back at 5700' above sea level and having to readjust. It's tough for an old guy! :) Did 5.2 miles this morning in 46:51. Not too bad especially considering that I woke up at 1:30 after only 3 hours of sleep -- thanks to jetlag.

Run well, y'all,
