I like to run but sometimes I fall out of a routine because of weather, too much work, school, or whatever other reason.
One thing that always gets me started again is knowing how much better I feel after a run.
The extra energy it gives me to make it through the day.
Following a running plan may help that will lead you to your goal of running a 5k and signing up for one perhaps.. For me it's always a motivator knowing I have a race coming up. Good luck!
