Dearborn Decades 5k

We are excited to once again be hosting our 5K in Dearborn and this year we will celebrate all the decades! This is a great mid summer race for all of our racers getting ready for their "A" race in the fall, and for the casual runner looking for a fun 5K course! Our fast and fun USATF Certified Course will give you a great shot at your PR. It would be a real bummer to miss this one!

This race is part of the Trivium Southeast Michigan Running Series, the Trivium Club Cup and the Trivium Mega Medal Series.  Athletes can earn points for themselves and their club for our end of season party. Your finisher medal will connect to other race's finisher medals to make one MEGA medal in the Trivium Mega Medal Series.

Dearborn Decades 5K is the 3rd race in the 6-race Trivium Michigan Mega Medal Series!

Register for six great Trivium Racing races at once!  Race in-person or virtually, earn your medals, and at the end of the year your six medals combine to form one giant Mega Medal!  Save over $150 on your 2025 racing by registering for the series.  Races include:
