FYI if you are preparing for a race or not preparing and willing to take your fitness seriously you need to be on a schedule and not miss a run.
If you have a busy day you need to try to fit a run at any time, prepare your running stuff at night in a bag to grab it in the morning on the go.
But be prepared, afternoons runs are usually not fun least for me, you are usually tired from work and your eating schedule is messed up.
However, if it doesn’t pay an immediate reward it will definitely pay later on, when you sit at night and remember that you did it despite everything, this will give you the mental power that you need.
And remember in order to get the runners high you need to pay for some bad runs sometimes.
