About this race
It's back!! Join us for the 3rd Annual Whittier Narrows Spring Running Festival where the miles are scenic, the vibes are high, and the lake views do all the work. Pick your party: A breezy 5k around Legg lake, a 10K Double loop with split timing, or go big with our NEW Half Marathon debut!
Flat, fast, and made for PR's, first timers, and friends who run for the snacks. Finisher bling, festival feels and that perfect May morning energy.
