12 Strong Details

To earn the 12 Strong patch, your ruck must weigh at least 47 pounds at the start. Water, hydration, and snacks count toward that weight; there is no dry weight requirement. You are welcome to participate with a lighter ruck, but it will not qualify for the 12 Strong patch.

Choose the $15 minimum donation for a 12 Strong patch, or $20 for 12 Strong & KanVet Patches. To earn the 12 Strong patch, start with a ruck weighing at least 47 lb and finish all 12 miles in 3 hours or under. The weight includes your water, hydration, and snacks; there is no dry weight requirement. The $20 option includes a KanVet patch regardless of finish time or completion. Additional donations alone do not include patches.

Optional Donation

Participation and volunteering are free. Add any extra amount you would like to support Kan Vets United. This is optional and separate from your patch selection. Additional donations have a $5 minimum. Leave the amount blank if you do not wish to add a donation.

I understand 12 Strong is a loaded endurance ruck with a cutoff. I am responsible for preparing safely, testing footwear and hydration, communicating issues, and following event organizer instructions.
