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.

    Join us for the Lung Legacy Run and Walk powered by Reel Free—a 10K run, 5K run/walk, and 0.5-mile walk with a heartfelt mission. This event is a tribute to the memory of the co-founders’ beloved grandfather, who battled pulmonary fibrosis.

    The Lung Legacy Run is more than just a race; it's a call to action. It's a reminder of the importance of healthy lungs and clean air. It's a chance to honor those who have suffered from lung conditions and to support those currently fighting these hardships.

    Through their startup company, which was awarded Student Startup of the YEAR 2024 by Michigan State University, the co-founders are working to increase the happiness and safety of people on supplemental oxygen, a cause close to their hearts. By participating in the Lung Legacy Run, you'll be joining a community united in the belief that everyone deserves to breathe clean air and enjoy healthy lungs. Together, we can raise awareness, support each other, and make a difference.

    Question: What's better than getting together bright and early and going for a walk or a run? Answer: Walking or running with credit union peeps at the Michigan Credit Union League Annual Convention and Expo to raise money for the Children’s Miracle Network!!!

    The Credit Unions for Kids 5K Fun Run/Walk for the Children's Miracle Network is powered by the Mid-Michigan Chapter of Credit Unions on Thursday, June 4th, at 7:30am!

    The run/walk will take place on the river walk - right behind the Amway Grand Plaza Hotel and DeVos Place. Easiest way is to get to it, is head towards The Kitchen by Wolfgang Puck, take a right and head out the door (you can exit out this door, you just cannot enter that way). Easy-peasy to find, just head toward the water. The 3.1-mile course starts on the riverwalk, will make a loop around the river walk, with a portion of the race veering off the river walk. You are free to run or walk whatever distance and pace, 1 mile, 2 miles, 3 miles, we got you covered!

    So, 7:30am is a bit too early for you or you won't be able to join us in Grand Rapids this year? No worries! Join us in spirit via our "virtual option"!

    By the way, this is NOT a timed event, and you get to decide how far you want to go! So, no need to get goofy about your time, just a fun and healthy way to start the day off on the right...foot! But the MOST important thing is...this is just another way to help raise money for the Children's Miracle Network!

    When: Thursday, June 4th

    Explore two parks in one race. Run (or walk!) through two beautiful Ottawa County Parks that sit along the Grand River. #2Parks1Race

    The Ottawa County Parks Foundation and Ottawa County Parks are excited to host this fun, family-friendly run/walk and celebrate the recently completed Idema Explorers Trail that connects Grand River Park to Grand Ravines Park. Come and enjoy nature, community, and some post-race treats. Ottawa County Parks are for everyone.

    The course starts at Grand River County Park, winding you through a natural surface trail until you hit the newly completed Idema Explorers Trail segment that leads you along the Grand River to Grand Ravines County Park. As you enter Grand Ravines, you will see an old covered bridge and go up a small incline to a spectacular view of the river. If you’re lucky, you might even see the resident bald eagles out fishing.

    If you are running (or walking) the 5K, you will turn around at this point. If you are running the 10K, you will continue to wind yourself through Grand Ravines Park, around past the dog park, through the meadow, across the Idema suspension bridge, down some stairs, and back through the woods to Grand River Park. Sounds pretty Grand, doesn’t it?

    Starting Time:

    The kids’ 1-mile fun run/walk will start at 8:00 am. The 10K and 5K races will start at 8:30 am.

    The kids’ fun run/walk will be on a paved trail only, so strollers will be allowed. (No strollers will be allowed on the 10K/5K route due to difficult terrain and narrow trails in some areas of the course.)

    Dogs:

    Dogs will be allowed to run the 10K and 5K races with their human, but they must be on a six-foot leash at all times. We know dogs are a part of the family, we ask that you be considerate of those around you and that you only bring a dog that is well-mannered and comfortable around people, including children, and other dogs. We want everyone to have a great time!

    Registration Price increases on April 1, 2026, for the 5K and 10K.

    • Kids' 1-Mile Fun Run price does not increase. Family discount available.

    Register before Saturday, May 30, 2026, to guarantee a T-shirt!
