Evel-When a running training plan, such as C25K, calls for a "rest" day, what it really means is a day off from running! I ABSOLUTELY think you should continue to exercise on your off days, just try and pick an activity that is not hard on the joints. Do cycling, swimming, elliptical, strength training, etc!! You can even supplement your running with additional exercise, such as the above mentioned suggestions. I personally HIGHLY Recommend/suggest you supplement your running with strength training, at least 2 or 3 X a week. Thats where you will REALLY see the results!!!
Im so glad for you that youre so psyched about running!! Its SO ADDICTIVE! The more adapted your body gets to running, the more often youll be able to do it as well, without adversely affecting your joints.
As for the carbs--yes, its true that ANY form of exercise utilizes glycogen for immediate energy. I trained for a marathon for 6 months on a "low carb"ish diet, and ran it successfully, while losing weight. Granted, my low carb wasnt like atkins or anything, just LOWER carb. I still ate fruit and whole grains and veggies with every meal. If you are in serious training for something, you would want to have a slightly higher carb ratio i suppose. But to be honest, i found the most helpful thing as I was training, was the HIGH protein part of my diet. Eating so much protein allowed my body to fully, and quickly recover between workouts ( i would run in the am, and then w/o with trainer or strength train in the evenings). It also allowed me to continue to INCREASE my muscle mass as my fat mass decreased. If, and when, you get to the point that you are running for more than 90 minutes at a time, thenyou will need to think about supplementing during your run with carbs, such as runners energy goos. And the only time you need to "carbo load" is before an endurance event, such as running a marathon, or a half marathon if you plan on it taking you longer than a couple hours to complete. I think you will do ok, as long as you are consuming SOME HEALTHY GOOD Carbs. But we are all different, and if you start finding you dont have the energy to complete your runs, then maybe you need to look into adding more carbs in!
