Tri Millennium

Tri Millennium

Tri Millennium is a two day multi sport event held July 24–25, 2026 at Millennium Park in West Michigan. The event includes Olympic and Sprint triathlon distances, duathlon and aquabike options, relay entries, and youth divisions for younger athletes.

The organizer lists the race distances for the main triathlon formats:

• Olympic race: 1,500 m swim, 24.8 mile bike, 6.2 mile run
• Sprint race: 750 m swim, 12.4 mile bike, 3.1 mile run

The park's inland waters are described as typically calm. The surrounding roads follow rolling terrain for the bike courses, and the park's paved trails are flat for the run segments. The event uses professional timing from Trivium Racing and is supported by volunteers and on course support on race day. Relay options are available for both main distances. Youth triathlon divisions are offered for ages 6 through 15 with shorter swim, bike and run legs. Tri Millennium names Bridge Street Ministries as its charity partner and states that 100% of donations from the event will go to support that organization.
