January 18th is the day.  I will be running in Arizona Rock-N-Roll Marathon and 1/2 Marathon.  Being that today is August 17th I have basically 5 months to get marathon ready.  From the articles, websites, and books that I have read, most say you need to run about 4 days a week.  The remaining 3 days you need to rest and/or do some cross training.  This presents me with a problem. I already go to the gym 3 days a week. If I maintain doing that it would leave no days for rest.  Not sure how I am going to work this but I know there is a solution.  Most likely I will have to just run on gym days also.  In the early weeks when the training runs are short it should be fine.  But when the runs get up to 10 miles plus this could cause problems.
