Competition fixure lists for the new season are available on the NIFU and IAFF websites. Ones of interest are:
NW Open 21st-22nd October Londonderry
Derry Open 18th November Londonderry
Irish Senior Open 2nd-3rd December Dublin
NI Open 13th January Belfast
NI Championships 24th March Belfast.
As well as these, the infamous Intervarsities will be held in February, by my reckoning it's Corks turn but don't quote me.
Now you have the dates, write them down and keep these days free. Competitive fencing is a great experience, you fence different people with different styles, meet other Irish fencers and there's always the after parties.
