My 30 Day Challenge

Great challenge! I would suggest that you determine your calorie needs for the active days and then go for a 500 calorie deficit each day, though. Doing marathon training on 1500-2000 calories sounds awfully low(?) If you go too low, your body will refuse to let go of extra weight (starvation mode) and slow down your metabolism - not a great idea before the race! I like this tool, because it allows for a lot of detailed adjustments: http://www.niddk.nih.gov/research-funding/at-niddk/labs-branches/LBM/integrative-physiology-section/body-weight-simulator/Pages/body-weight-simulator.aspx

Thank you! It will definitely adjust and fluctuate. My off days, I will lean harder toward the 1500, and the 'on' days, more towards the 2000. Fortunately, it's a 1/2 marathon as opposed to the full. I'm actually interested in how my body will go for it - if I don't get the results that I expect, then I will adjust for sure!
