So I just finished plowing through Born to Run by Christopher McDougall and it's really opened my eyes to all or the little I knew about running. Personal insights aside it's an interesting and funny read mixing cutting edge anthropology, science and some excellent story telling. But, onto the cool science stuff.
The author wants to be a runner but is constantly plagued with injuries even after running short distances. In a last ditch effort to overcome his injury prone ways he heads to the Copper Canyons in the Mexican dessert like Skywalker seeking Obi Wan to find a reclusive tribe of ultra runners. The Tarahumara Indians of Mexico have practiced running up and around and through the canyons in the dessert up to 50 miles at a stint,
for fun. People of all ages run effortlessly for miles and miles through dangerous switchbacks and canyons under the searing dessert sun without so much as the latest and greatest sneakers, hydration packs power gels or a even good pair of socks. They slap on some cheap sandals and set off for a cool 50. After spending a few days with Tarahumara he heads home to do some research and see if science can explain how they do what they do, as well as apply some of what they do to his own body.
So how is it that the Tarahumara peel off 50 miles at a time in cheap sandals without showing any injuries? Apparently it's our own fault. It's our shoes. The human foot is perfectly engineered to run long distances but we feel compelled to wrap it in all sorts of fancy rubber and trappings to prevent it from doing this that and the other thing. A long long time ago Neanderthals roamed the planet. They were happily chillin' when somewhere along the way homo sapiens dropped in. Of the two species Neanderthals were stronger, tougher, had harder-to-break bones, bigger brains and better natural insulation against the cold. Yet within a scant 10,000 years of their arrival homo sapiens were the only kids left on the block, the Neanderthals were gone. How did the strongest smartest and sturdiest lose to the weak one? Neanderthals lacked the ability to run. After the great big winter died down and the jungles and canyons gave way to great big open plains the Neanderthals way of hunting with spears and bow and arrow didn't do them any favors, you can't hunt an animal with a spear that can see you coming from miles away. Sure they could sprint or jog a short distance but they couldn't flat out run like we humans can. Have you ever heard of any creature in the animal kingdom running for 26 miles at a time without stopping? They don't because they can't. Homo sapiens are perfect engines of locomotion we have legs full of springy tendons the ability to sweat to release excess body heat and the ability to breathe while running. All pelt covered creatures release heat by panting and can't take multiple breaths and run at the same time. Point humans. Animals can sprint for a short period of time but ultimately have to stop and pant to release built up heat. Humans also have arched feet and short flat toes perfect for running. That's great that we can run like hell for a long time but that doesn't help us when a cheetah for instance can do laps around us and then turn us into hamburger. It's the endurance not the speed that set us apart and put us at the top.
The author found a tribe in Africa that still hunts animals by persistence hunting-running an animal down until it's exhausted and THEN hurling your spear at it. So that's how we did it. We simply ran animals down until they couldn't move anymore and killed them. Opposable thumbs don't hurt either. Hello top of the food chain.
All this talk of primitive life on the plains sans the newest running sneakers and sans any injuries lead to a blurb about the barefoot running world and the
Vibram Fiver Finger shoe. All the information taken together presents a pretty compelling reason to go barefoot. The Beautiful and Awesome Wife and I recently ran a 10K with a friend of ours who was sporting the Fiver Finger shoes. She's been running with them for awhile and really enjoys them and did quite well in the race. She was a bit sore after the race but then again we all were. The Fiver Finger shoes do lend themselves well to other activities i.e. water sports which we do plenty of. That and you feel like you're barefoot how cool is that? I'm certainly intrigued by them and the thought of running in them. I'd like to give it a shot but I haven't arrived at the I want to run barefoot table yet. Maybe sometime I'll shed the chains that shod and answer the call to running barefoot.
