Women are unlikely to catch men in the marathon

Someone recently pointed to me to this misleadingly-headlined article which revisited the 1980s speculation that women might eventually prove to be faster than men at marathons. The headline (“Catch her if you can”) and photo caption (“Do women have a secret weapon when it comes to jogging speed?”) seem to suggest that the premise has […]

Carbo-loading: An idea whose time has passed?

In 1967, a landmark study led by Bjorn Ahlborg found that military recruits could improve their ability to perform endurance tasks after a carbohydrate depletion and loading regimen over the preceding week. The dietary restrictions were quite extreme, and were coupled with exhausting exercise: A hard workout followed by three days of a low-carb diet, […]

The Basics: How far did I run?

This is the second of a pair of posts on the issue. On Friday, I discussed a 2009 report […]

The proposition: Beer is better than water for rehydrating after a hard workout. The article cites study results “published in the British newspaper The Telegraph.” This “news” […]

A complex picture on marathoning and heart disease

Jim Fixx was an overnight sensation as a recreational runner who had worked himself into shape and written a book about the health benefits of running. But when he died of a heart attack shortly after a run at age 43 52, he became the poster-child for the idea that running can actually be hazardous […]

Welcome to Science-Based Running

A little over a year ago, I weighed 40 pounds more than I do today. A good run for me was three or four miles, at a pace of about nine minutes a mile. Now I can run that same distance at faster than a seven-minute-mile pace. A year ago, the farthest I’d ever run […]
