Number of sub 3 hour finishers from Cork clubs in the Dublin Marathon

Following on from the Dublin Marathon, I had a closer look at the results of club runners from Cork. In particular, I had a look at the number of sub 3 hour finishers and the result was different from what I expected.

I thought the number of sub 3 hour finishers might be spread out across the various clubs but they're not. I did a comparison with 2016 and 2017 and the results are shown below...

As you can see, Eagle AC and St.Finbarr's AC have the highest number of sub 3 hour finishers. In 2015, the two clubs accounted for 50% of all the sub 3 hour club finishers from Cork. In 2016, that went up to 68% and this year, it's 74%.

What's really suprising are the low number of sub 3 hour finishers from other clubs.

In terms of total numbers of Cork club runners going sub 3 hours, there were 20 in 2015, 25 in 2016 and 27 in 2017.
