On 16 November 2025, the City to the Sea Half Marathon & 5K returns, beginning downtown in San Luis Obispo and concluding at Avila Beach. The half marathon runs through scenic backroads, past vineyards, rolling hills, and includes segments on the Bob Jones Trail before arriving at the oceanfront finish. The 5K (Avila-Seaside 5K) runs mostly along coastal paths, harbor views, and beachside surroundings, giving pull of ocean scenery. The event includes shuttle service, post-race festivities, live music, race expo, and refreshments at the finish. It also serves as the primary fundraiser for Cuesta College’s cross country/track teams and draws both local and visiting runners seeking a picturesque course and a coastal Californian running experience.
