Tri Millennium

Tri Millennium is a well-established multi-sport competition that welcomes athletes of all levels—from those attempting their first triathlon to experienced competitors seeking a summer challenge. Held at Millennium Park, the event offers multiple distance options: an Olympic-distance race featuring a 1,500-meter swim, 24.8-mile bike, and 6.2-mile run, plus a Sprint-distance option with a 750-meter swim, 12.4-mile bike, and 3.1-mile run. Relay teams are welcome for both distances. The park's calm waters, rolling terrain on the bike course, and fast paved running trails create ideal conditions for racing, and organizers provide professional timing and volunteer support throughout the day. This event supports a meaningful cause—all donations benefit Bridge Street Ministries, a local organization dedicated to the spiritual, academic, and social growth of young people on Grand Rapids' West Side. Whether your family includes a triathlete preparing for a major event later in the summer or someone ready to cross off their first triathlon finish line, Tri Millennium offers an inclusive racing experience backed by strong community support.
