TriMillennium is a sprint and olympic distance triathlon, duathlon, and aquabike race hosted in the beautiful Millennium Park, located on the west edge of Grand Rapids.  TriMillennium has historically been one of the favorites in West Michigan, attracting both local and out-of-town athletes. After taking 2018 off, the TriMillennium is excited to be back for 2019 to compliment the fantastic race community here in Michigan.

Located on the edge of Grand Rapids, TriMillennium is easily accessible with ample parking at the park.  Athletes and spectators alike will enjoy this race.

Whether you are a brand new athlete, or a seasoned veteran, TriMillennium is a great race for you.  The shallow waters of Millenium Park offer pleasant and calm water.  And our flat a fast bike and run courses make TriMillennium a great option for your “A” race, your first race, or anywhere in between.

For you elite athletes we will offer an elite wave that will send off several minutes before the rest of the pack.  This wave is meant for experienced triathletes that want to compete with others of similar ability without interfering with the newer athletes.  There is no cost to participate, just respond accordingly during registration.  Please use discretion when considering if this is for you.

Injured and can’t run?  No worries!  TriMillennium includes an aquabike option for both distances.

Terrified of the swim? Good news for you… we also have a dualthlon for our sprint and olympic distances.

Have a few of you that want to participate together.  Great!  Relay options are also available.  Racing is always more fun with friends. There really is not a good reason NOT to do this race!
