Marjorie Rinaldo is a professional road cyclist from Tucson, Arizona, known for her strength in individual time trials and stage racing. A lifelong athlete, Marjorie’s foundation in endurance and power began in high school, where she competed in swimming and track & field while also lifting weights with her dad — a formative experience that sparked her passion for sport. Following the birth of her daughter in 2011, Marjorie transitioned into triathlon, combining her background in swimming and running with her growing love for cycling. She earned her professional triathlon license in 2019 and began racing at the pro level in 2021. Her talent and competitive drive soon led her to specialize in cycling, and she made a full switch to road racing in 2022. Since then, Marjorie has rapidly made her mark in the U.S. domestic cycling scene, delivering strong performances in national time trials and multi-day stage races, including the Tour of the Gila.
