It will see the distinctively illustrated Mercedes-Benz-powered children's ambulance pushed all the way from Dingle to Dublin.
Spearheading the venture is Tony Heffernan, the powerhouse behind The Saoirse Foundation and Bumbleance.
Bumbleance is the world's first interactive children's ambulance service established to provide free transport for children from all over Ireland to and from children's hospitals, respite, treatment centres and hospices.
Fronting the project with him is well-known Kerryman and fellow Dingle resident, ice explorer and adventurer Mike O'Shea.
The aptly named Mega Push will see a special Bumbleance vehicle being pushed from Dingle to Dublin, a distance of 355 kilometres along a route that will take it over the Conor Pass and onwards on a nine-10-day push through the towns and villages of Camp, Castleisland, Templeglantine, Adare, Birdhill, Moneygall, Mountrath, Monasterevin and Kill, finishing in St Stephen's Green on September 20.
Commenting, Mercedes-Benz Commercial Vehicles Sales Manager Fergus Conheady said: "We are proud to have been involved in the Bumbleance project from the word go and to see our familiar Mercedes-Benz three-pointed star motif adorn the fascia of such a special and worthwhile vehicle."
