ironguides Coach Jono Rumbelow decided not only to talk the talk but to walk the walk; it was time to lose a few kilograms. Here are the guidelines he successfully used to do it, and you can too.

ironguides Coach Jono Rumbelow takes a look at hyponatremia, a dangerous condition that results from mistakes in the intake of salt & water. Endurance athletes are especially at risk as the temperature increases, both on race day and in training.

The world of nutrition is one of the most complex and controversial, so trust ironguides coach Jono Rumbelow to write another article about it. The coach who fuels his training with a ham sandwich with butter and mayo on brown bread (weird, he knows, but it works for him, he says) has listed the 45 ingredients, and their purpose, most commonly found in widely available energy drinks.

These issues can limit your performance and derail your training and racing. Lack of proper nutrition will cause the above problems.

In this video, Ben Greenfield shows you the dirty foods in his refrigerator, and why these dirty foods are actually just fine for a clean triathlete to eat.

If you're like me, you care about your skin looking healthy and good. Frankly the state of skin health scares me when I go to a marathon or a triathlon, or spend time with folks who have been "outdoorsy" much of their lives. It's like looking at a wrinkled elephant face. Do people who exercise outdoors just not care about the way their skin is going look when they're 50, 60 or 70?
