Overall, it is definitely one of the best half marathons in Ireland and a fun adventure with a varied course you won’t forget.

#2: Cork City Half Marathon 

The Cork City Half Marathon is often considered to be one of the best half marathons in Ireland due to the pleasant course, the friendly atmosphere, and how well the race is organized.

This Ireland half marathon takes runners through the historic and cultural hub that is the city of Cork.

The race starts and finishes on Saint Patrick’s Street, and it is one of the biggest half marathons in Ireland in terms of participation.

What’s great is that there is a Cork City marathon, 10k, or marathon relay as part of this festive weekend, meaning that all of the runners in your family or clan can join together in the festivities.

The marathon relay is becoming increasingly popular, as it is a fun way to participate in a marathon when you aren’t yet ready to tackle the full 26.2 miles on your own.

You might want to consider that option instead of tackling the half yourself if you like the idea of running with a team. You can read more about the benefits and what it is like to be part of a marathon relay team here.

In terms of the Cork City half marathon route, it is generally described to be a flat and fast half marathon in Ireland.

That said, because Ireland certainly has its share of hills and dales, there are some rolling sections, so what might be considered the “flattest half marathon in Ireland“ isn’t necessarily pancake flat in the way you might find in other parts of the British isles.

However, the course is generally pretty forgiving, with most of the hills in the middle.

One great thing about this half marathon is that the organizers welcome walkers, making it one of the best half marathons in Ireland for beginners.

Note that the roads do open back up to traffic after 3.5 hours, but you can keep going.

Overall, while runners love this Ireland half marathon, it takes place at the end of June so temperatures can be quite hot on race day and there are sometimes complaints that there are not enough water stations.

If you decide that the Cork City Half Marathon is indeed the right choice for you on this list of the best half marathons in Ireland (it does have a lot going for it), you might want to consider wearing a hydration pack.

#3: Dingle Half Marathon

The Dingle Half Marathon takes place around the gorgeous Dingle peninsula, with the Dingle Marathon taking place on the same day. 

The half marathon course is beloved for the breathtaking scenery as the courses wind along the beautiful rugged coastline, with some areas affording magnificent views of the Blasket islands. 

The majority of this scenic Ireland half marathon course is right along the sea. The route also takes you through idyllic villages and historical sites. 

Once you have run through the cute village of Ballyferriter, you are treated to special views of Murreagh, before tackling some grueling hills

Though you’ll be panting after this extremely tough section, your work will be rewarded with sweeping views of the entire landscape. It’s by no means an easy course, but it’s absolutely one of the most scenic marathons in the world.
