Princeton 5K

Saturday March 21, 2026
8:30 AM

Now in its 17th year, the Princeton 5K continues to represent 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.

For those under 10 who aren’t up for the full 5K, the Kids Dash offers a fun but challenging 300m loop. Every participant will receive a youth-sized t-shirt and wear bib #1 with pride.
