Trenton Summerfest Half Marathon, 8K & 5K Trenton, MI   Jun 27, 2026

Kick off summer running with Trenton Summerfest – fast miles, river views, and festival energy, featuring a Half Marathon, 8K and 5K. Start your season strong on a course built for speed and good vibes. The Half Marathon begins early to help you beat the heat, offering a flat, scenic route with just 96’ of elevation gain. The 8K adds rolling hills through beautiful Elizabeth Park before bringing you into downtown Trenton, and the 5K is perfect for both PR chasers (the record is 15:24.07!) and anyone looking for a fun run or walk with friends.

As the second race in the Trivium Mega Medal Series, your finisher medal connects with five others to form one massive, display-worthy piece. Whether you’re racing for time, community, or summer momentum—this is where the season starts.
