FAQ

What is the standard?

To earn the 12 Strong patch, your ruck must weigh at least 47 pounds when you start. You can participate with a lighter ruck, but it will not qualify for that patch. Water, hydration, and snacks count toward that total; there is no dry weight requirement. To earn the 12 Strong patch, select a patch donation and complete all 12 miles in 3 hours or under.

How do the patch donations work?

All patches and donations are optional. Select 12 Strong patch for a $15 minimum donation, or 12 Strong & KanVet Patches for a $20 minimum donation. Both choices require you to start with at least 47 lb and finish all 12 miles in 3 hours or under to earn the 12 Strong patch. The $20 choice includes the KanVet patch regardless of finish time or completion. You can add an optional additional donation of $5 or more; an additional donation alone does not include patches.

Can I volunteer?

Yes! Volunteers are welcome and can make an optional additional donation. Volunteers do not take part in the ruck, receive event times, or qualify for either patch, so patch choices are disabled for volunteer registrations.

Where is the route?

The route is an out-and-back on the Prairie Sunset Trail between Goddard and Garden Plain: start in Goddard, turn around at Garden Plain around mile 6, and finish back at Linear Park around mile 12.

What should I train?

Loaded walks matter. Test footwear, socks, electrolytes, hydration, and foot care before event day. Small gear problems become big problems over 12 loaded miles. For footwear, socks, and pack ideas from local PAX, read the F3 Wichita community gear guide (PDF).

What does this support?

12 Strong supports Kan Vets United, a Wichita-area volunteer foundation helping local veterans with practical needs like housing, utilities, food, and emergency support.

Timing Model

The challenge is measured by three clean marks: step off together, make the Garden Plain turn, and finish back at Linear Park in 3 hours or under to meet the 12 Strong patch time requirement.
