At baseline participants will wear a Fitbit for one week and attend the Runner's Assessment. After this the participant will begin to run 3 times per week for eight weeks. Every week, participation in a virtual support group with the physical therapist, research coordinator, and other research staff will be expected. Rest-activity cycles' data will be monitored; if at any point the runner is not able to complete 3 runs per week, participants will be encouraged to contact research staff the issues for this (such as medical problem or scheduling difficulty) and formulate plans to remediate the situation. Participants that would like to continue the treatment for an additional eight weeks will have additional data collected.

Participants will also wear the Fitbit through-out the study and complete surveys during the study and have blood drawn.

Feasibility and acceptability of the study will be the completion of running sessions based on the Fitbit and or self-report.

This is a self-report questionnaire designed for the purpose of assessing anxiety, mood, eating, and substance use disorders. For the first section (9 questions) the participants will select from Not at all (0) to nearly every day (3).

The next section asks if in the past year participants felt depressed or sad most days (yes or no) and if so, not difficult at all to extremely difficult. The last question participants are asked about suicide. Scores of 5, 10, 15, and 20 represent cut points for mild, moderate, moderately severe and severe depression.
