E-RACE THE STIGMA
We are continuing our charity takeover! In partnership with the Rotary Club of Ann Arbor we are committing all our fundraising efforts to organizations that help and support mental health and/or issues associated with mental health and play an active role in reducing the stigma surrounding mental illness. You will learn about them during registration, and we hope you will choose to support one or many to help E-Race the Stigma!
