WTA All Access Pass & Rucking!

 
🚀 Skip the Lines With The WTA All Access Pass! 🏃‍♂️

WTA All Access Pass?

Your ticket to skipping the packet pickup line and heading straight to the start line! 

How It Works:
✔ Register for the series in any distance 🏅
✔ Opt out of a shirt 👕💰- this automatically gets you the pass
✔ Receive a reusable ankle strap for timing ⏱️ 
✔ No check-in required – just show up and run! 🏃‍♂️🚀

More running, less waiting—because race day should be about the trails, not the lines. 🌲

Important Notice:
Your All Access Pass is non-transferable. Sharing your pass with another individual is not permitted. If someone else uses your pass, you will forfeit your access privileges.

Thank you for respecting this policy—it helps us keep the program fair for all participants.

Rucking at All Events!

Rucking is a physical activity that involves walking or hiking with a weighted backpack (called a rucksack). The term comes from the military, where soldiers train and operate carrying heavy loads over long distances. In civilian fitness and recreation, rucking is gaining popularity as a versatile and low-impact workout. We now offer it at all Wisconsin Trail Assail Events!

More information about rucking.
