By now you should be noticing the difference in your fitness level and your overall energy. You should be enjoying the activity and starting to explore future possibilities for your running. At the end of this 5 week program you should be capable of entering and completing a low key 5k or 8k fun run or race. Don't expect to win, just complete it, have a good time and get the T-shirt. The current level of training will keep you aerobically fit and support an occasional short fun run.
Basic fitness is a great running goal.
If you want to increase your level of training, first set some new goals that are within your reach in the next 4 to 8 weeks. You could start by doing some running on 1 or 2 of the easy days you have taken off. This should be limited to 800 - 1200 meters. You could start replacing the walking warmup and cooldown with slow running until you can run the entire workout. As you continue with your running we encourage you to periodically go back and revisit the 10 running commandments we have given you in this series.
