Welcome to the Official Pendleton Round-Up RU-vid page! Check back for event updates, exclusive interviews and the day's highlights from down on the grass. While the rodeo is the heart of the Round-Up week, the Round-Up refers to all of the excitement that draws thousands to Pendleton in the second full week in September each year. Pendleton’s Main Street is closed to motorized traffic and becomes a carnival grounds with vendors and live music throughout the week. Whether it’s the Happy Canyon Night Show Pageant, the Indian Pow-Wows and vendor booths, the Westward-Ho! Parade or the nightly shows on Main Street, the whole town transforms into a fun-filled festival with something for everyone.
