🆕 New for 2026 - Rucking!

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.

• Offering: We now offer it at all Wisconsin Trail Assail Events!
• Information: More information about rucking.
