Organisers of this year's Royal National Mod will embark on 104-mile trek to help raise funds for the Gaelic festival.
The Mod was first held in Oban in 1892
At least 12 people, including Falkirk provost Pat Reid, will walk from Fort William to Falkirk, where the event is being held.
More than 10,000 people are expected to attend the Mod, planned for October.
The walk will take seven days and re-trace former droving routes used by cattle dealers centuries ago.
Traders from the Highlands and islands would converge on Falkirk district to sell their livestock at the annual trysts.
Following the sales, the drovers would gather for ceilidhs in the area.
Locals believe it was these gatherings that sparked the idea for a festival celebrating Gaelic culture, and is why Mod 2008 is using the slogan "The Mod is Coming Home".
Those taking part in the trek will follow the drove routes and take part in a special re-enactment of the cattle droves planned for the final leg of the journey at the Falkirk Wheel.
Organisers are looking for businesses, groups or individuals to sponsor each mile of the walk.
Councillor Angus MacDonald, chairman of Mod 2008 Falkirk, said: "The Royal National Mod is a major event in the Scottish calendar and will attract up to 10,000 people to Falkirk district in October.
"Fundraising is an important element of the Mod Committee's functions.
"Money raised from our fundraising efforts will allow us to provide a number of Fringe events over and above the official Mod programme, and will ensure that Mod 2008 in Falkirk will be a truly memorable event.
"The traditional music scene in Scotland is going from strength to strength and Falkirk will play its part in the exciting developments that are taking place, not just this year but in future years to come."
