Where you go next with running really depends on what you want to do with it. Your personal needs and goals should drive your choice of "what next." What do you want to do? Do you hant to try for longer and longer race distances? Do you just want to maintain a certain level of running for health reasons? Do you like creating your own program or do you want to follow someone else's? Do you want to join a running club or keep running on your own? A lot of people jump right from one program into another because they like the structure of not having to figure out what to do next. Others say "I need a break from training plans" and keep going on their own. Yet others finish the program, can't answer the question "Now what?" and quit. Or realize they've reached their goal by running in a race, realize they don't really like running, and try something else. What you do next is the big question. You know you can run for a half hour three times a week without hurting yourself. Now you need a new goal. Until you pick that goal, no training plan is better than another. So... What do you WANT to do?
