Barefoot Running and the Perfect Beat

Blame it on Born To Run.

No, not the Bruce Springsteen album or song, but the book by Christopher McDougall chronicling his journeys among ultramarathoners, a native Mexican tribe of (seemingly) superathletes, and his own running pain. The main point of the book is: everything you know about running is wrong. Specifically, shoes. All that padding and stability and motion control just gets in the way of the natural sensory feedback your feet give you when you run barefoot, leading to bad running form and eventually, for most people, injuries. To put it bluntly, the shoes are indirectly causing the very injuries they're supposed to be preventing.



I have been running more or less regularly since the fall of 2000, when my wife and I found out we were expecting our first child. At the time I didn't lead an unhealthy lifestyle exactly, but I wasn't getting a great deal of exercise either, and if I wanted to be around to see this kid grow up, I needed to take better care of myself. I joined a gym, started on cardio machines, transitioned to treadmill running and outside running. I ran my first Peachtree Road Race in 2002 and did quite a few races over the next few years, mostly 10Ks but also a few 5Ks and one half-marathon. Some nagging injuries led me to give up running for a couple of years, but I found I really missed it so I made the effort to start up again in 2010 - about the time I learned about Born To Run. The book was a revelation, and made a lot of sense to me - after all, humans have been running barefoot for thousands of years - do we really need expensive, high-tech shoes to keep from injuring ourselves? I tried some barefoot running but the bigger impact (no pun intended) on my running came in the form of some more minimalist shoes and more careful attention to my form.

McDougall's book talks a good bit about correcting your running form, as merely taking off your shoes isn't enough. Most of us need to unlearn years of bad habits, such as landing on your heels, developed from running in highly-cushioned shoes. Correcting one's running form isn't easy, even for McDougall, who had the benefit of some of the best running coaches around. I found some YouTube videos and other sites which helped, but I wasn't sure I was on the right track. I felt like I needed some coaching, but I'm basically too cheap to hire a personal trainer; plus, all this barefoot/minimalist running stuff, as trendy as it was, was still new, and I doubted that there was an abundance of coaches out there who knew what they were talking about.

Fortunately, the good folks at Big Peach started to offer Good Form Running classes for a modest fee. This technique, very much in line with the barefoot running craze, divides running form into four areas: posture, mid-foot landing, cadence, and lean. Breaking it down like this lets you work on one thing at a time. The cadence part is particularly simple: aim for 180 strides per minute, or 90 per minute on each foot, which will give you a shorter, more efficient stride, while at the same time discouraging you from landing on your heels. I had known about the 180 strides per minute guideline for some time, and briefly tried running with a metronome, but I wasn't crazy about it. However, the class suggested running with an iPod playlist consisting of songs with tempos at 90 or 180 beats per minute. I hadn't thought about doing this before, but it made a lot of sense for me - I run with an iPod Nano (although usually listening to podcasts), and I have a lot of music in iTunes. Surely some fraction of the thousands of songs were at the correct tempo, right?

In the next post I'll discuss my efforts at putting together a playlist of suitable songs.

I'm Feeling Ducky

I have used Google products for a long time. I started using their search engine back around 2000 or so, when they were still in their lengthy beta period, and most other people were still getting by with AltaVista, Yahoo, or whatever else passed for web search in those days. When Google search exploded in popularity, I had my share of early-adopter smugness, and soon took it for granted that with enough search wizardry I could find anything.

Likewise, I was an early and enthusiastic adopter of GMail in 2004, which I continue to use for my main account, and now my work account (although I didn't make that decision). Although we keep a paper calendar on the fridge, it doesn't get written on much anymore as our lives have migrated to Google Calendar. Google Documents has become a handy permanent-and-accessible-anywhere location for various lists and other handy documents. Picasa rapidly became an easy tool for managing, editing, and uploading family photos - to Google servers, of course. (Then there's the blogging platform you're reading now, of course). I even used Google Desktop Search on my old Windows XP machines, which was approximately 15253% better than trying to find a file using Windows's own search capability. If it's on that black Google toolbar, I probably use it. (OK, Google+, not so much.) In short, Google has insinuated itself into my life pretty heavily. If they cared to look, they could probably learn just about anything about me.

Which brings me back to search.

About a year ago I was listening to a Hanselminutes podcast about a search engine called DuckDuckGo. It's a general-purpose web search engine that does all the usual spidery-crawly indexing, while adding some interesting touches of their own. Their search results have more emphasis on noncommercial, curated sites such as Wikipedia and Delicious, and deliberately avoid content farms such as Answers.com. They have an interesting "Zero-click Info" feature: where possible, you'll see a box at the top of the search results with a brief synopsis or definition, again from curated sources. If you're keyboard-driven, they have scads of keyboard shortcuts, so for instance you can search for a book on Amazon by typing "steve jobs biography !amazon" (or just "steve jobs biography !a" if you're into brevity). Finally, they make it a point not to track you. This earned DuckDuckGo a Class A rating from Terms Of Service; Didn't Read, a new website that is trying to distill the terms of service of various websites into plain English (and presumably other languages).

Up to this point, I could count on one hand the number of non-Google web searches I had performed over the last 10 years or so. (Bing just seemed... slow, cluttered, and not that compelling.) But I admired the audacity (insanity?) of going up against a juggernaut like Google, so I gave DuckDuckGo a try, and I liked what I saw. Soon it was my default search engine on Chrome (my browser of choice, natch) and Firefox.

I still respect Google as a company, and feel that they try to adhere to the "Don't be evil" motto when possible (although perhaps not as much as a few years ago). They still provide my email, calendar, browser, and more. But, with privacy on the Internet being easy to lose and difficult to regain, I like having that big "search" egg in a different basket.
