The walk will go from Sedgley to Molineux Stadium, in Wolverhampton - the home of Mr Cox's football team Wolves - on Saturday, September 19.
People are being asked to meet outside The Clifton pub, on Bull Ring, at 12pm.
They are set to appear before Wolverhampton Crown Court today.
A fifth man charged with violent disorder and actual bodily harm is also set to appear.
Members of the public have been invited to join Mr Cox's family and friends on the day of the walk.
The event's organiser said: "This tragedy has really touched me and my family so I just thought this would be a opportunity, as a community, to all come together."
