That last Sunday you've marked down (April 15th) there's an event in Ross Castle and also the IMRA race on Claragh Mountain at 7pm...
I'm in County Waterford on the night of the 14th, then plan on going to Fota (wildlife park, not orienteering) if the weather is good on the way home, getting dinner at home on the way back to Kerry, so doubt i'll make either at this stage.
