Bath at Play's Spring Colors Half-k Color Run

Event Overview

This is the Bath at Play Spring Colors 5k and Half-k Color Run. It is an annual event. The 2026 edition will be held on Sunday, May 17, in Bridge Park in Bath, Maine. This is the event's second year.

Race Format

The event features two un-timed, non-competitive color runs. The 5k is an out-and-back course through downtown Bath. The Half-k is a shorter loop along the waterfront, designed for children; participants can complete multiple loops. The 5k runners start first, allowing them to finish and reunite with younger participants. Volunteers scatter along both courses to apply colored powder to runners.

Registration Details

Registration can be completed online. There is an early-bird registration period from March 1 through April 15, 2026. On race day, registration and check-in opens at 7:30 AM at Bridge Park. Day-of registration is available but pre-registration is strongly encouraged to help the event start on time. Adult registration (18+) is $35 and child registration (0-17) is $10. Families with three or more registrants receive an automatic $5 discount per person.
