1. Train Smart: For your first 5K (3.2 mile race), it is recommended that you train for at least six weeks leading up to it, especially if you are not a runner. There are elaborate training programs, but don’t be afraid to keep it simple. Three or four moderate runs a week is enough. No need to drive yourself crazy or burn yourself out. Vary your distances. For example, if you plan to run on Monday, Wednesday, and Friday, make the Wednesday run 5-6 miles, and make the Monday and Friday runs 3-4 miles. Go easy on yourself during the final week of training. Two days before the race, give your legs a rest. The day before, go on a short, easy run to keep your legs loose.
