About the Event

The Princeton 5K is ready for you in 2025! In its 17th year, the Princeton 5K represents all that is good about community in-person events. Athletes - young and old, big and small, fast and not as fast - come together year after year to run or walk while generously supporting the Princeton High School Cross Country and Track & Field teams.

The 5K race is an IN-PERSON only event this year on Saturday, March 21.

In 2026, we are continuing to offer the KIDS DASH. A challenging 300m loop for all children under the age of 10 years! All participants will receive a youth t-shirt to wear with pride.

We hope to see the whole family on race day!
