Malin to Mizen

Malin to Mizen is the traversal of the entire length of the island of Ireland between its two extreme points: Mizen Head in County Cork and Malin Head in County Donegal.
The route is attempted by cyclists, runners, walkers, and motorists, and is sometimes undertaken to raise money for charity or as a personal endurance goal.
As the crow flies, the two points are about apart. The shortest practical road route measures roughly, while most modern traverses cover between depending on the chosen course.
