I am currently working on getting my base mileage back up and I need help. I plan to run the Los Angeles Marathon in March and I need a training plan. I am currently running very little and I don’t think I will be able to handle the FIRST plan for this marathon. I only want to run 3 times a week (maybe 4) and I will cross train on the bike (and maybe swim). Goal marathon time is 4 hours. Suggestions?
