Kick Off Summer Running with Trenton Summerfest

Half Marathon, 8K, & 5K

A lot of thought went into making Trenton Summerfest the perfect early summer race! With an early start for the Half Marathon, athletes will get a chance to beat the heat! The Half Marathon course is gorgeous, fast, and flat with only 96’ of elevation gain. The 8K course offers a little more variety with rolling hills in gorgeous Elizabeth Park at the start. You’ll also enjoy the Trenton Summer Festival atmosphere in downtown Trenton! The 5K is a great race for a fast time (the course record is 15:24.07!) or to get out and enjoy a fun run or walk with friends.

For an added level of excitement, this race serves as the second race in the Trivium Mega Medal Series. The finisher medal, along with 5 others, connect to create one giant medal!
