I think we can assume now that there's a chronic aspect to her injury. She injured her knee and ACL while snowboarding in Colorado in her late teens. Was fine for the next 20+ years but maybe father time is catching up with uncared issues..
XC is important in an irish club runner's calendar. It's subdivided into three classes: novice, intermediate, and senior (which means "open" here). Geographically, there's official events at county, region and national levels. Plenty of races in short. Compared to the US where i did XC (bay area/northern CA), the courses are much tougher - lots of mud, rain, hail, tall & uneven grass. Distances are 10k for senior, except nationals (12k).
As far as i know, there's nothing like NCAA in Europe, let alone Ireland. I wish there was. Obviously it comes with huge budgets... What always amazes me though is that despite the pool of incredible talents in D1 and the semi-professionnal training regimen, the US is not all that strong in distance running on a global scale. Do students just burn out, get bored or pursue other interests?
Mark Carroll is known in the running world, but the most famous distance athletes would be Eamon Coghlan , John Treacy, Jerry Kiernan (sadly passed away recently).
I see Eamon Coghlan regularly, he likes a pint of guinness in a pub next door to me. A true gentleman, very humble. He was senator but never got into the politician game.
Ger is easy to pronounce, it's just like "Jer". You spelled Dun Laoghaire better than 99% of Irish people! Here's an anecdote: Dun Laoghaire used to be the main ferry port between the east of Ireland and the UK and France. Now, the only regular passenger boat to/from Dun Laoghaire takes you to .... Dublin! I took it last summer, it's a slow and quiet cruise through Dublin's port and industrial past. Somewhat interesting!
