 22m (though 23m closer)
 * Gaelic Athletic Association
 * proposed 1917 (presumably as anti-British gesture)
 * accepted 1975 (starting 1976?) 50y --> 45m and 70y --> 65m
 * "profile reporters and commentators still simply refuse to use the official metric terms adopted by the Association in 1975"
 * IAAF
 * 1976 for 1977 abolished all non-metric distances except mile (marathon non-round in both)
 * for 1963 field events official metric with imperial to nearest quarter-inch and rounded up
 * hurdle heights and field event length and weights mix of metric and non (presume all now defined in metric; when did rounding-down of imperial measurements take effect?)
 * USA Outdoor Track and Field Championships: men's used metric in Olympic years from 1928, and all years 1932–1952; once-off 1959, and all years from 1974. Women's from 1975.
 * The Athletics Congress abolished metric except mile in 1978.
 * Boxing at the Olympics: pre-WW2 used pounds even in metric countries. Who organised? Check official reports. Weight class (boxing): "When the AIBA was founded in 1946 to govern amateur boxing, it metricated the weight class limits by rounding the pounds values to the nearest kilogram."
 * Commonwealth Games
 * Athletics went metric in 1970.
 * Swimming went metric in 1970 too.
 * Track cycling events is weird:
 * "10 mile scratch race" all the way to 1994, though might latterly have been 16 km.
 * UCI distance is 15 km, World Championships scratch date from 2002
 * "4000 m individual pursuit" since 1950, though early might have been 2.5 mile.
 * Swimming: "FINA ruled in 1956 that starting 1 Jan 1957 they would only recognize metric marks made in 50 metre pool." — does that mean wouldn't recognise yard marks, or wouldn't recognise metric marks set in non-50 metre pools?
