Im really interested in training for a fitness figure competion. Im already in the gym pretty much 7 days a week sometimes twice a day. Well the problem is I love to run. So Im also doing a marathon and a few 10milers this year. Is it possible to do both the runs and the competions. I have found over the past few months if I cut down on carbs and increase protein I can really see my muscles and from weight training Im getting faster. The only problem is when I cut down on carbs I also get more fatigued on longer runs, so after about mile 12 I feel tired. I would really like to compete but dont know how to do both without one suffering, has anyone here done this?
