2026 Trenton Summerfest Half Marathon, 8K, & 5K

Kick Off Summer Running with Trenton Summerfest
Trenton Summerfest offers three race distances—Half Marathon, 8K, and 5K—all starting in beautiful Elizabeth Park and designed for a great early-summer race experience.
The Half Marathon features a fast, flat, PR-friendly course with just 96’ of elevation gain and an early start to help athletes beat the heat. The 8K adds a little variety with rolling hills early on, while the 5K is perfect for chasing a quick time (course record: 15:24.07) or enjoying a fun run or walk with friends.
Expect smooth organization, well-stocked aid stations, great awards, and strong on-course support—hallmarks of a Trivium Racing event.
Trenton Summerfest is also the second race in the Trivium Mega Medal Series, where each finisher medal connects with five others to form one giant Mega Medal at the end of the season.
