The Paris Marathon’s Footsteps Generate Electricity

It’s common knowledge that running is a high-impact sport. Approximately three times the runner’s weight is imparted into the ground on every step. And the legs impart energy as they push and pull over the ground. That’s a lot of energy. What if you could translate that energy into electricity? Could we use it to light up some homes?

That’s exactly what the race organizers of the Paris Marathon were thinking this year. The race sponsor, Schneider Electric SA, in conjunction with Pavegen Systems Litd. of the United Kingdom, conducted a test using flexible, energy-harvesting tiles, made from recycled truck tires.

Laid across a 25 meter section of the Champs Elysees, the tiles were designed to convert some of the kinetic energy that each footstep generates. The tiles work by flexing about 5mm on every footstep, which can generate up to 8 watts of kinetic energy. The resulting energy was fed back into batteries.

The 40,000 runners who participated in the race generated 4.7 kilowatt hours of energy, enough to run a fluorescent lamp for 146 hours.

Imagine if every sidewalk and low-traffic street in every city was covered with these tiles. Human movement itself could become a powerful generator for the world’s energy requirements.

Don’t Be That Awkward Runner

Physical education - Awkward Runner VideoAs a running coach, I see all sorts of technical errors in my runners. Especially from those who have patterned themselves after television or running magazines and THINK they are emulating those models.

In fact, what an athlete thinks they are doing often doesn’t match reality.

In this video, called “Don’t Be That Awkward Runner,” you’ll see some over-exaggerated, humorous examples. But the funny thing is, while exaggerated, I’ve encountered variations of every one of these awkward runners. For example, I’ve seen runners with unstable core, floppy arms, no arms, foot contact ahead of the center of mass, no arm action, heel contact first, over-wide stance, straight arms, over-exaggerated arm lift. All are exhibited in this video.

The video has labels for some of these running styles that may someday become part of the running coach’s lexicon: “the Geezer,” “the Dandy,” “the T-1000,” “the Flightless Bird,” “the Stiffy.”

Enjoy the video and whatever you do, don’t be a “Flightless Bird.”

Jenny Simpson – World 1500 Meter Champion – on Dealing With Disappointment

Here’s an excellent interview for those of you who must deal with athletes who have experienced a disappointing performance…and what coach hasn’t dealt with that situation!

In fact, it’s so relevant that you might want to email a link to such athletes so they can watch it themselves.

The interview is with Jenny Barringer Simpson. Jenny, currently 26 years of age, won a surprise gold medal in the 1500 meters at the 2011 World Championships in Athletics. She is also the American record holder in the steeplechase with a time of 9:12.50.

Here’s a sample of her philosophy: “But I can tell you from past experiences, you can’t win them all, but you can be a fighter in every circumstance.”

I’m having some formatting problems, so I’ve had to put her interview at the very bottom of the page.

Also, here is footage of her World Championship win. She was not favored to win and the look of shock on her face after the race is priceless (I think the commentary is in Spanish). Her interview about disappointment did not take place after this race.
