Before you know it, you are running a 5k! But a lot of runners have a hard time making improvements after they have become comfortable with 2-3 mile runs. You want to continue to build your endurance and run a little further or longer. Maybe you even want to run a 10 miler or half marathon, but itâs daunting.
