Two things I noticed when running on the treadmill.
First, the first few minutes are a real pain. Legs are heavy, breathing irregular, body tense. Makes me want to give up right away.
Second, when I focus on the screen with pace, distance, and time, running feels a lot more difficult – mentally and physically – than when I focus on the wall 10 meters ahead of me.
The point being.
Getting started is rarely pleasant. And when you eventually get started, focusing too much on what you see right in front of you will make you lose perspective and vision, therefore decreasing your motivation.
