The walk raises money for veteran suicide awareness and prevention.
The walk, which is a 20 mile or 2.0 mile march, begins at Stadium View Bar and Grille and travels throughout Green Bay.
Some of the participants will also carry 20-pound packs during the walk.
"That 20 pounds is another way to make the journey more difficult, to put you in the shoes of what we think the veteran may feel like: alone, deserted, stranded," explained William Kocken, president of 4th H.O.O.A.H. "Some of the things that they say, people feel before they determine they want to take their own life."
The walk begins at 10 a.m. Registration is from 6-9 a.m.
