Outside: The Marathoner's Achilles Heel

How to Strengthen Your Ankles and Run Faster 
Alex Hutchinson/Outside Online, Sep 13, 2018

New research zeroes in on an unlikely culprit for why running gets less efficient as you fatigue.

Anyone who has scrolled through their own marathon race photos knows that the keen-eyed high-stepper who shows up in the early photos bears little resemblance to the pathetic hobbler of the final miles. Fatigue changes your running form, and yet the vast majority of biomechanics studies involve a few minutes on a treadmill at a comfortable pace. There are some exceptions (like this recent field study of marathoners at the World Championships), but much of our knowledge about running form assumes that we never get tired...

Runners' World - Better Run For Shade?

How to Handle Running in the Heat
Richard A. Lovett/Runners' World, Jul 26

However many bad-weather-will-make-you-tougher quotes we collect, there’s still one aspect of weather that most of us do our best to dodge: heat. In fact, many of us do everything we can to avoid it: running at dawn or in the late evening or even seeking shelter on treadmills in air-conditioned gyms. It is, however, possible to run in heat.

In the 1996 Atlanta Olympics, Portuguese distance star Maria Fernanda Moreira Ribeiro set an Olympic 10,000-meter record under hot, humid conditions (82 degrees with 60 percent relative humidity, according to historical data from Weather Underground). In the process, she posted a time of 31:01.63—one that 16 years later would still have put her in the top 10 in the much more temperate conditions of the London Olympics. The bottom line is that the human body is remarkably adaptable to heat. Its ability to adapt to high temperatures is faster and more dramatic than its ability to adjust to any other environmental stress that nature can throw at us, such as altitude or cold...

NY Times - I Wanna Be Accelerated...

Nike Says Its $250 Running Shoes Will Make You Run Much Faster. What if That’s Actually True?//Kevin Quealy and Josh Katz, New York Times, 18 July 2018

If a running shoe made you 25 percent faster, would it be fair to wear it in a race? What about 10 percent? Or 2 percent? The Nike Zoom Vaporfly 4% — a bouncy, expensive shoe released to the public one year ago — raises these questions like no shoe in recent distance running history.Nike says the shoes are about 4 percent better than some of its best racing shoes, as measured by how much energy runners spend when running in them. That is an astonishing claim, an efficiency improvement worth almost six minutes to a three-hour marathoner, or about eight minutes to a four-hour marathoner.And it may be an accurate one, according to a new analysis by The New York Times of race data from about 500,000 marathon and half marathon running times since 2014...

CTS: Adjust These, Run Faster

Run Faster With Less Effort With These Four Adjustments
Adam St. Pierre/CTS Running Coach and Biomechanist

There are many factors involved in running biomechanics, including body weight, limb length, muscle strength, joint range of motion… and everybody is different in these respects. That’s why there is no singular ideal that defines perfect body mechanics. Rather, each individual must find their own ideal biomechanics. Watch any elite marathon and you’ll see many examples of “perfect” biomechanics – Eliud Kipchoge looks like he’s floating! But you’ll also see examples of elite athletes running amazingly fast with seemingly serious biomechanical flaws. Whether you’re elite or just getting started, here are four areas every runner can optimize to run faster with less effort.

Optimizing the four areas below can lead to faster sustainable paces at a given effort level/power output. It may reduce injury risk by reducing the strain on body tissues – which in turn improves performance by minimizing missed/compromised training...
