Tri Millennium

Tri Millennium is one of West Michigan's longest-standing multi-sport events and a favorite among many local athletes. Located in the beautiful Millennium Park in Grand Rapids, MI, Tri Millennium offers an Olympic and Sprint distance triathlon, duathlon, and aquabike. 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 inland waters of Millennium Park are typically calm and pleasant, the surrounding roads follow the rolling terrain for the bike course, and the paved trails through the park are flat and fast, making Tri Millennium a great race for the elite athlete looking for a summer "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, Tri Millennium is a race for everyone.

Tri Millennium's charity partner is Bridge Street Ministries, a Christian urban youth ministry in Grand Rapids' West Side, working to support the spiritual, academic, and social development of inner-city youth, leading them with a vision of hope and restoration and believing that they will be the future leaders of our community. 100% of the donations from Tri Millennium will go to support this important work.
