Mike Sheehan and his 27 mile bicycle route in West Cork.
'Newsround' visits the town of Goleen, where for over 40 years, local postman Mike Sheehan has cycled and walked with the post, anything up to 30 miles a day.
His friends calculate he has worn out a total of 22 bikes, 96 pairs of tyres, 240 pairs of brake pads, and that at a conservative minimum, he has cycled the equivalent of ten times around the Equator, just doing his job.
But the mountain terrain makes for some steep climbs and the other two Goleen postmen prefer to use a car or a motorbike. Does this mean it is the end of the line for the cycling postman?
