One of West Michigan’s longest-standing triathlons, and a favorite among many local athletes.  Located in the beautiful Millennium Park in Grand Rapids, MI, TriMillennium offers an Olympic and Sprint distance triathlon.  Our Olympic race features a 1,500-meter swim, 24.8-mile bike, and 6.2-mile run.  Our Sprint distance race features a 750-meter swim, 12.4-mile bike, and 3.1-mile run.  Relay options are available for both races.

The Millennium Park lake typically offers calm, pleasant water, and our run and bike courses are flat and fast, making TriMillennium a great race for the elite athlete looking for an August "A" race, a beginner athlete looking to complete their first triathlon, or a primer race for those prepping for the MiTi half or full triathlon later in August.  With professional timing from Trivium Racing and a full complement of volunteers and support on race-day, TriMillennium is a race for everyone.    

100% of proceeds from TriMillennium will go to support the inner-city youth of Grand Rapids, helping provide them with opportunities to succeed.  For more information about our charitable partners, visit bsmgr.org.
