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.

For 2026, Millennium Meadows Marathon is proud to be hosting its 9th year! We will feature a Full Marathon, Half Marathon, 10k, and Marathon RELAY. All four events will take place Sunday, August 30th.

Again this year we are offering a referral program! Once you register you'll see a referral link that you can share via social media or email, with whoever will signup. Once they register using that code, YOU will be refunded $5 per person. It's good for as many times, until your registration is fully refunded! Who doesn't love money back?

Secchia Meadows provides the perfect course for a team relay, with each relay leg being roughly 4 miles. Round up a team and come compete. We'll set up a relay row, where teams can place tents and have a great time.

Millennium Meadows Marathon events occur at Secchia Meadows in Millennium Park, one of the many Kent County Parks and what we think is the most scenic and beautiful. You will run on a wide and paved path that crosses a footbridge, winds along the Grand River, and cuts through meadows. Most of the course is heavily shaded.

We are a proud supporter of the Kent County Parks Department and Team World Vision - Grand Rapids. Use our Donate button on the left menu, select which organization and follow the steps.

A Race Series Designed by Runners, for Runners

In 2021 we created the McKirdy Micro Marathon series to help athletes run a personal best and qualify for the Boston Marathon or beyond. At the time, we were just coming out of the COVID-19 pandemic where opportunities to run fast times were limited and motivation to continue training was difficult with no races on the calendar.

In 2023, we took the same concept and applied it at an elite level, hosting a race for athletes targeting the USATF Olympic Trials Qualifying Standard (OTQ) or the Olympic Standard. Many “on the cusp” athletes find they have limited options for races that are both fast and will provide the support they need to run their best.

Athletes from all over the world came to participate in a small localized race with the potential for massive impact. When the day was done:

48 athletes ran under the 2:18:00/2:37:00 OTQ Standard

More OTQs came from our race than any other race in 2023

Our race produced 2 Olympians

69% of the finishing athletes ran a personal best

85% of the finishing athletes ran their second fastest lifetime marathon

Moving forward, we are expanding the series to bring the McKirdy Micro race experience to athletes of all abilities over multiple distances! We hope you’ll come run your fastest marathon with us.
