OK....here's a snippet in line with what I'm talking about.....does this ring true with y'all other runners?
Keep in mind....that you only really need to carb load if you're doing more than 90 minutes of high-intensity exercise. Although a tough kickboxing class, a speedy 10K or even a three-hour afternoon spent on your feet shopping may kick your butt, the fatigue you feel usually isn't from depleted energy stores. "If you're running a 10K, you're running for less than an hour, so carb loading is unnecessary as long as you've been eating a high-carb diet and have rested the day or two before," says Craig Broeder, PhD, clinical exercise physiologist at Benedictine University in Lisle, IL.
I'm only running 1.5 miles (i.e. not a marathon) but with the speed I have to maintain with my larger-than-average frame.....I want to leave little to chance as far as keeping my edge as sharp as possible.
