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! I can’t wait to ride with you.” - 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. Join me at the SLO Ultra this year." - Krissy Moehl

"Here is your opportunity to experience the private mountain trails of Wild Cherry Canyon on the beautiful California Central Coast. Oak woodlands, rolling hills, lonely single track trail and stunning views of the Pacific Ocean. Do yourself a favor, come with me to the SLO Ultra weekend....You deserve it!" - Luis Escobar
