The riverside course provides a natural, scenic backdrop, making it a popular choice for local athletes and families alike.
Registration Deadlines
Online registration for all distances remains open through race day, Sunday, March 29, 2026. Late registration on the day of the event will be subject to "Last Chance" pricing.
