Building Bridges

In West Michigan

The Millennium Triathlon is a Bridge Street Ministries event.  BSM is a Christ-centered, inner-city youth ministry that works to disciple, equip, and empower under-resourced youth from the West Side of Grand Rapids.  Proceeds from TriMillennium go to help us accomplish that mission.  Learn more at bsmgr.org

Race History

After a year off, TriMillennium is back for its 11th year.  What started out as a sprint triathlon has grown into a local favorite with sprint and Olympic distance races.  We are excited to be back!!!
