Headbanger Half

May 20, 2026 Important Course Update Due to permitting conflicts with Waukesha County, we were unable to secure final approval for the original Headbanger Half Marathon course. After working through several course options, we have officially secured approvals in Summit, Wisconsin — the location of Silver Circle’s very first half marathon 17 years ago. The new course is flat, fast, rural, low traffic, and includes shaded sections of the Glacial Drumlin Trail, plus scenic areas near Laura Lake and Golden Lake. We understand course changes are not ideal for everyone. If you would like to defer, switch to another Silver Circle event, or request a refund, please email info@silvercirclesportsevents.com.
