Good for: Analysis of the newest research in exercise physiology.

Written by: Amby Burfoot, Runner’s World Editor at Large and 1968 Boston Marathon champion.

Burfoot brings decades of experience as a runner and journalist to his blog for Runner’s World. He combs through the newest research on exercise and performance, putting together detailed but highly readable posts on fueling for marathons, running form, and the health benefits of exercise. Posts range from quirky ("Did You Know Runners Are More 'Financially Conscious"'? Me Neither") to serious ("Dehydration and Hyponatremia: How Common? How Dangerous?") Over the years, Burfoot has interviewed just about every exercise physiologist of note. That gives the blog some real intellectual heft, without ever feeling hefty.

Sample Post: Burfoot connects a study of an ultrarunner named Philippe Fuchs with questions about stride rate and the world's best sprinter, Usain Bolt.

First, how is Bolt like an ultrarunner? Easy. Neither cares much about running economy. Bolt consumes oxygen like a fireball. He doesn't even have to breathe during a 100. If he goes deep into oxygen debt, it's no big problem, because he's going to stop in a second or two.

Strangely enough, running economy doesn't matter to ultrarunners either… Why not? Because running economy isn't crucial to an ultrarunner. You don't require a super cardiovascular system to pad along at 10 to 12 minutes per mile. You need a body that just won't break down. You need to improve your mechanical efficiency, but not necessarily your oxygen efficiency. …
