What You Should Know About Electrolytes

By Coach John Hughes  On average, if you are riding in moderate conditions each hour you’ll produce 600 to 800 ml (21 to 27 fl. oz.) of sweat! In extreme conditions, you could easily produce 32 fl. oz. (1 quart, or 1 liter) or more of sweat per hour. Sodium is the primary electrolytes lost in sweat, along with some potassium. According to the American College of Sports Medicine (ACSM), if your ride is less than four hours, you probably don’t need to supplement with electrolytes unless your jersey is caked with salt or you cramp. If your ride is longer than four hours, then additional sodium and potassium are recommended.

Tour de France Continues to be Controversial

By John Marsh  Another week of the Tour de France, another dose of controversy. This seems to be a Tour destined to be most remembered not for epic racing but for the realization of many of the potential negatives inherent in the race. I don't know about you, but on my rides with buddies last week and this, one hot topic of conversation continued to be Peter Sagan's disqualification. And the other was the incredible crash-marred Stage 9, which took out 11 (I've also read 12) riders on the day.

RBR Favorites: The Computers We Use

Editor's Note: Some time ago, a Premium Member wrote in to ask if we could update an article we ran in which a couple of us on the RBR Crew provided a quick rundown of our favorite tires, and why we liked them. It was an excellent idea. So good, in fact, that I immediately decided to make it a regular feature – providing a rundown from RBR Contributors on our favorites across the spectrum of components, nutrition, clothing, accessories, you name it. Today we discuss our computers. (Here's a link to the gamut of RBR Favorites.)
