UCI and IAAF affiliated bodies were subsequently affiliated to the OCI, thus regularising the position of Irish competitors in those sports at the Olympics. Members of the all-Ireland National Cycling Association (NCA) with Irish Republican sympathies twice interfered with the Olympic road race in protest against the UCI-affiliated Irish Cycling Federation (ICF). In 1956, three members caused a 13-minute delay at the start. Seven were arrested in 1972; three had delayed the start and the other four joined mid-race to ambush ICF competitor Noel Taggart, causing a minor pileup. This happened days after the murders of Israeli athletes and at the height of the Troubles in Northern Ireland; the negative publicity helped precipitate an end to the NCA–ICF feud.
