Following months of fundraising, the challenge began on Thursday April 24 at a meeting point on the M50, where the fleet set off to visit hospitals in Dublin, Waterford, Drogheda and Galway, before returning to Dublin last Sunday, April 27.
The fleet delivered over €100,000 worth of life-saving equipment for prematurely born babies that the bikers and their supporters raised money for earlier in the year.
Joe Harris, CEO of SsangYong Motors Ireland, said: "We are proud to support such a worthy cause. The fundraising has surpassed all expectations.
"Countless lives will be saved as a direct result of these determined and generous bikers, and it is an honour to offer our support vehicles to them as they journey across the country."
