If you fancy going to see some real racing in Ireland, the Cookstown 100 is at the end of April and will have some top riders there http://www.cookstown100.com/
The one i would recommend to anyone is Armoy Road Race "race of legends" Full grids and an amazing atmosphere http://www.amrrc.com/
Both these races are within half an hour of Belfast ferry terminal and you can get some amazing deals from http://www.nutttravel.com/
Well worth a look and some local Aberdeen/Scottish riders will be at most of them
