  A Dusk-til-Dawn Fundraiser for the Coastal MS Wildcats Track & Field Program!

  Are you ready to join the frenzy? Lace up your shoes for an overnight endurance challenge like no other. Whether you're a seasoned trail runner or a casual walker, the 12hr Frenzy is your chance to push your limits, support the Wildcat team, and experience the Harrison County Fairgrounds under the stars.

  The Challenge

  The rules are simple but the task is tough: 2 Kilometers. Every Hour. For 12 Hours. In the Dark.

  HEADLAMPS ARE REQUIRED

  • Start Time: 7:00 PM (Friday Night)

  • Location: Harrison County Fairgrounds, MS

  • The Loop: A 2km (1.24 mile) trail circuit.

  • The Goal: Be in the starting corral at the top of every hour. If you complete all 12 laps, you’ll have conquered 24 Kilometers (nearly 15 miles!) by the end.

  Why Participate?

  This isn't just a race; it's a fun and challenging way to support youth athletics. All proceeds go directly to supporting the Coastal MS Wildcats.

  • Finisher Honor: Finishers will receive a custom dog tag.

  • Basecamp Vibes: Bring tents or camp chairs for a place to rest and recover between loops. We will have several fire pits to help stay warm. Please bring your own food and water.

  • Entry Fee: $35 (additional donations are appreciated)
