Protesters will walk about 40 miles between Daytona Beach and Sanford over the weekend, starting Friday, the Orlando Sentinel reported.
The group, called the Dream Defenders, said the march is a "stand against racial profiling, institutional racism and the legacy of violence that continues to plague young people of color."
Martin, 15, was fatally shot Feb. 26 by self-appointed neighborhood watch captain George Zimmerman. Zimmerman claimed the shooting was in self-defense and has not been arrested.
Meanwhile, CNN reported Thursday Zimmerman told his lawyers he whispered "[expletive] punks" while on the phone with a 911 operator, not a racial slur, as some people believed.
Tom Owen, who analyzed 911 recordings, said after using technology to clear the audio track, he has become convinced Zimmerman said "punks."
