The Mamore Gap has been used regularly in Rás Tailteann; riders often shocked at how difficult it was. The climb itself is short and at 1.1 kilometres it lacks the length, but what it lacks in length, however, it makes up for in how steep it is. Not only will you need to be in exceptionally good shape to get over the top of it, but you’ll also have to face up to the fact that there are most likely going to be flocks of sheep all over the road.
