Island Spring Half Marathon

We kick off the Island Race Series with a fundraiser for the Alameda Hospital Foundation. 2026 is special because we have added a Half Marathon to this event

Run both the Spring Half and the Island Festival Half and receive a customer "half and half" hoodie.

This race will take place at Faction brewery and feature all the beautiful views, flats course and post race expo that you are used to at our September event.
