Anxiety is when a person worries excessively, feels apprehensive, is restless, irritable, tense, stressed, or easily fatigued. Everyone experiences anxiety. However, if it starts to interfere with your daily life making some lifestyle changes and/or seeking therapy may be something to consider.
In the spirit of self-care I've created the first of many "challenges". You've maybe seen similar challenges floating around on pinterest, instagram, and the like. I thought I'd try my hand at it and create a challenge for people interested in reducing/managing their anxiety that already have an established running routine. Exercise has been shown to be an effective tool for managing stress and anxiety. Other effective tools are meditation, deep breathing, and relaxation trainings.
If you don't run this can easily be adjusted for walkers. Walking produces many of the same stress relieving effects as running.
I'd recommend runs/walks reflect your current practices, or build your endurance gradually.
