Orangemen and unionist politicians have announced details of a 10-day "long walk" from Derry which will arrive in Drumcree on the day the disputed parade is due to take place.
The organisers described the event as "a Protestant human rights walk". They said it would be peaceful and they simply wanted to uphold civil liberties for Protestants and support Drumcree.
The 117-mile walk will start in Guildhall Square in Derry on June 24th and will arrive in Portadown on July 4th. There are plans for up to 38 feeder parades linking into the main march along the route.
The Rev Stephen Dickinson of the Orange Order said: "We've been bombed and bullied and attempts made to bribe and blackmail us, and to rob us of our rich heritage. We feel like strangers in our own country. We believe this project is going to stir the heart of Ulster Protestants that their cause is just and right."
The Parades Commission will rule today on whether the march - which takes in towns including Limavady, Coleraine, Ballymena and Lurgan - can go ahead. In a visit to Belfast earlier this week, the British Prime Minister, Mr Blair, appealed for a resolution to the Drumcree dispute.
Further proximity talks are expected to be held between Orangemen and Garvaghy Road nationalists.
Ulster Unionist councillor Mr Jonathon Bell, who is one of the organisers said the "long walk" should be allowed to take place as it threatened no one.
"Our only interest is the human rights of the Protestant community. If the walk is banned we will be appealing directly to every European government, the European Union and the United Nations to stand up for our rights."
He said around 50 core marchers would walk the entire route with many more expected to join in along the way. "We've been absolutely inundated with support since we started planning this. There will be marshals and every effort has been made to ensure safety and that those taking part are law-abiding, but we are not responsible for security in Northern Ireland."
He said the event was inspired by Martin Luther King's civil rights marches. Protestants' rights to live free from murder and intimidation had and were still being violated in Northern Ireland, he said and he demanded parity of esteem for unionists.
Also on the platform at yesterday's launch were Ms Michelle Williamson, whose parents were killed in the Shankill bomb, and Mr Jim Dixon, who was injured in the Enniskillen bomb.
Mr Brian McConnell and Mr William Frazer of the south Armagh victims' group FAIR were present. Several Assembly members, including Mr Paul Berry of the DUP and Mr Norman Boyd of the Northern Ireland Unionist Party, attended.
Mr McConnell said: "We have been murdered in our churches, reading our bibles, with no justification or reprisal, and intimidation continues. We have no peace process or peace dividend. We are delighted at last there is a platform which will allow innocent victims to be recognised."
