A blessing will be held on "Mad Sunday" to remember TT rider, Paul Dobbs who was killed during racing in 2010.
The 39-year-old from New Zealand died in a crash at Ballagarey during the second Supersport race on 10 June.
His wife Bridget is hoping as many friends as possible will come along to pay their respects.
She said: "Dobbsy knew so many people so TT week seemed like a good time to get people together."
She added: "It has obviously been a particularly emotional year but I have had so much support from people around me and the biking fraternity.
"Everyone jokes about what we would do without Facebook but seriously it has been a life saver, really brilliant".
The blessing will take place at 1130 BST on Mad Sunday 5 June at Lonan Parish Church.
On Mad Sunday the circuit is opened to motorcyclists to allow them to travel on the same tarmac as the Superbike riders in the TT.
