The Marble Rally is a tournament of fast-paced outdoor races that puts speed and control at odds with one another, creating a vacuum in which marbles race down a course with bends, twists, and straight sprints to the finish line. There are no heats or teams in this series – each athlete rolls for itself in each race to obtain medals and score points towards an overall total, albeit with a system more competitive than the Marble League. The marble with the most points at the end of the season wins the Marble Rally and qualifies for the next season.
