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.

This year, we’re making things easier by preassembling team packets. If your team has 4 or more members by 9:00am Wednesday, June 3rd, you’ll be able to pick up the entire team’s bibs and shirts at packet pickup in one convenient bundle. The Team Captain may pick them up or designate someone else on the team to do so. Please only send one team member to pick up for the entire team.

If your team does not meet the 5-member threshold, each team member can pick up their packet individually.

📣 Important: If your team qualifies for group pickup (4+ team members), individual team members will not be able to pick up their individual packets.

The packets will include:

Race shirts

Race bibs with labels (name, shirt size, bib number, gender, age and event).

Please let your team members know if you used your email to register them, they will not receive these race day instructions or other important information, so please forward this email to them.

The start and finish lines are downtown in front of Oz Plaza!
