The S3 Turkey Trot has been a tradition in Detroit for over 40 years!
Much more than a variety of races (10k/5k/1 mile), thousands of participants dress in costumes for the event. Often declared “The Parade before The Parade”, participants frolic by the largest spectator crowd in Michigan. Truly an awesome way to start Thanksgiving Day!

Every February, thousands of undie runners in cities across the U.S. come together, whether it be in-person or virtually, to support those affected by NF, a group of genetic conditions that cause tumors to grow on nerves throughout the body.
Cupid’s Undie Run kicks off with drinking and dancing, then we jog it out with a mile(ish) run and end it all with an epic dance party!

Join us on Sunday, March 29th, 2026 for the 7th annual Strides for Adam 5k run, walk and 1 mile reflection walk. We are also offering a virtual event for those that are unable to participate in-person.
Suicide is the SECOND leading cause of death for ages 10-24. More teenagers and young adults die from suicide than from cancer, heart disease, AIDS, birth defects, stroke, pneumonia, influenza, and chronic lung disease, COMBINED.
On Dec 26, 2018 this unfortunate statistic affected Adam Holten, his family, extended family, friends and the community. We lost a very good person to suicide. Adam affected many people’s lives with his presence, his smile, his laughter, his handshakes and his ability to reach out and lift other people up.
Since his passing we have created a non profit organization – Strides for Adam to continue his legacy of service to others and keep his memory alive.
