The 4th Rat Race, hosted by the Huron Booster Club, is an annual fundraiser to support all sports offered at Huron! Home of the River Rats, Huron is a comprehensive high school in the Ann Arbor School District, with a student population of nearly 1900 students. It has one of the largest populations of Schools of Choice students and low-income students in Washtenaw County.
Why is hosting important? Research shows that high schoolers who participate in sports manage stress better, feel a stronger sense of community, and are at low risk of engaging in risky behaviors. We want to make interscholastic athletics accessible to all students.
