From the organizer

Organizer's website

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 600-meter swim, 12.4-mile bike, and 3.1-mile run. Relay options are available for both races. 100% of proceeds from TriMillennium will go to support the inner-city youth of Grand Rapids, helping provide them with opportunities to succeed.

Course Details
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.
