What our Race SLO ambassadors have to say about the SLO Ultra Dirt Festival:

"San Luis Obispo is a cyclists dream. Being part of the inaugural Race SLO mountain bike event satisfies two mission’s close to my heart. Riding in a spectacular area and also supporting the hard working partnerships necessary to keep recreational trails open to all of us. Thanks Race SLO and The Land Conservancy of San Luis Obispo!” - Rebecca Rusch

"Combine your passion for running with passion work to protect the places you play! Give the miles that your legs cover greater meaning." - Krissy Moehl

"Here is your opportunity to experience the private mountain trails on the beautiful California Central Coast with oak woodlands, rolling hills and lonely single track trails. Do yourself a favor, come with me to the SLO Ultra weekend....You deserve it!" - Luis Escobar
