Snow Patrol singer Gary Lightbody is to participate in a Walk for Peace from Belfast to Derry in honour of the deceased 29-year-old journalist Lyra McKee.
The journalist was shot dead while watching disturbances in Derry in April.
The walk will take place between May 25 and May 27, beginning in Belfast's Writer's Square and ending 68 miles later at Ebrington Square in Derry.
Lightbody will join the walk for the final stretch at Dungiven and it is anticipated that he will speak at the conclusion of the walk.
The event will feature performances from artists including Hex Hue, Lyra's Choir and Abby Oliveira.
The organisers have assured participants that the walk "will not become a platform for politicians or political groups."
