Is Bolt best-ever?

never ratified as world records, but in 1886 in Boston, Wendell Baker (USA) ran 22.0 for a straight 220y on June 14 and on July 1 clocked 10.0 for 100y and 473/4sec for a straight 440y!

And back in the pioneering days of women’s athletics, three British athletes did the trick. Mary Lines (11.6 100y, 12.8 100m, 26.8 220y, 62.4 440y between 1921 and 1923), Eileen Edwards (11.3 100y, 25.4 200m, 25.8 220y, 60.8 440y between 1924 and 1927) and Nellie Halstead (11.0 100y, 25.2 220y, 56.8 440y between 1930 and 1932).
