Become a Ridge Runner today! Run the Ridge 5k run/walk is designed to help promote fitness throughout Chaska and surrounding areas. It also is a healthy way for our school to raise funds to help improve technology for our students at Pioneer Ridge Middle School. Last year, in it's first year, we had just over 300 participants, and were able to raise enough funds to help enhance a computer lab to make it able to house an entire class. Our course is unique as well! It starts and ends right at the middle school, but goes down into a ravine, along a stream, through some tunnels, across two walking bridges and through the fields of Chaska High School. It really is a beautiful course!
