Cancer survivors will be creating an 'arc of light' across Dublin Bay this evening
The event will kick off from two locations in Dublin at 5pm.
Everybody who takes part will be walking with their lit torches from Blackrock Park and Woodenbridge, as well as leaving from Donnybrook, and will converge at Sean O'Casey Bridge at around 6pm.
From there, they will take part in the Survivor's Celebration Lap, before lighting the Torch Of Hope cauldron at CHQ.

Mairead Mangan, the Head of Fundraising at the ARC Cancer Support Centres, said: "It's a walk suitable for all fitness levels with people able to join in at any point that best suits them along the route. We need as much support as possible to help us to meet this growing demand by people signing up to take part or sponsoring those who are."
Jennifer Hogan, who has survived cancer, has taken part in the Torch of Hope Relay before and says it is the highlight of her year, telling 98FM: "There's such a sense of camaraderie, of us all being in this together, of everyone wanting the very best for each other."
"If you were feeling down before the Torch of Hope Relay, you'll be feeling a thousand times better afterwards - it's hugely inspiring and uplifting. For those of us who have survived cancer, it's about grabbing life by the bootstraps and living it to the full. I would encourage people to lend their support in whatever way they can."
Organisers say that there will be some surprise celebrity guest appearances at today's event, including a special performance by Aslan front-man Christy Dignam.
