When I coach runners online, I have them keep a log that tracks their stats including the shoes they wear, the temperature and elements, the terrain, time, distance, run-walk intervals and more. I also have them rate how they felt overall during the workout with a color code.
Green: I felt strong and could have done more today.
Yellow: I felt okay, but nothing to write home about. I didn't feel awful, but I also didn't feel particularly strong either.
Red: I was in the bite-me zone for much of the workout, and struggled to finish. I cast an invisible spell on the woman who looked so happy running in front of me.
By color-coding your workouts, you begin to see trends in how your body responds to the workouts. If you see lots of green and a few yellows, you are on the right track and your body is recovering well. If, however, you begin to see a trend in consistent yellow and some red, something is affecting your recovery rate. It's time to modify your training frequency, progression rate, sleep, nutrition, stress, travel, lack of downtime, the elements and more.
Learning to run by monitoring your pace is like being in love with a toxic person. With every stride comes judgment that you're not fast enough. It's best to log the activity as close to the finish of your run as possible so it's fresh. As time goes by, you'll also begin to see your progress right before your eyes. And that's when running starts to get fun.
