Former Blue Toon striker Martin Johnston, who also played for Cove Rangers, Elgin City and Brechin City, was diagnosed with the condition in 2018.
And seven ex-Balmoor players will be among a 25-strong squad who will run over a 24 hour period from noon on Saturday.
All proceeds going to rugby legend Doddie Weir’s ‘My Name’5 Doddie’ foundation - Martin's chosen charity - which is raising awareness and funding for research into MND.
An initial target of £5,000 has already been reached.
The event is being organised by ex-Peterhead player who will be joined by former Scotland player and Peterhead manager Ian Wilson as well as assistant boss Alan Lyons and fellow former Blue Tooners Craig Cooper, Mark Perry, Stuart Soane and Kevin Tindall.
The remaining players, including a clutch from Fraserburgh, all either played with or against Johnston with runners spread all over Scotland.
Robertson, who has set up a Just Giving page for donations, said: "Once we came up with this idea with Martin, we set up a group chat with all the runners. The banter in it has been tremendous and when you consider some of us have not seen each other for 10 years it is remarkable how quickly we have bonded.
“In fact, we could have given out the slots three times over as there are so many ex-players keen to help in the fundraising.”
