Rich Roll writes memoir and endurance-sport non-fiction about addiction recovery, plant-based eating, training and the reshaping of daily habits. Finding Ultra recounts his movement from alcohol dependence and an unhealthy middle age into long-distance endurance events, including Ultraman competitions, using training and diet as part of a broader personal recovery narrative. The Plantpower Way, written with Julie Piatt, shifts towards food and household practice through plant-based recipes and lifestyle advice. Voicing Change collects conversations and reflections connected with health, purpose and personal development. Roll's writing is motivational and autobiographical rather than technical sports science, with major life change providing the structure. His work fits endurance memoir, recovery writing, plant-based lifestyle and fitness self-help, especially for readers interested in transformation stories built around running, cycling and swimming.
