Career
He also was a coach at Dartmouth College. He had Olympic record times in all three events, but Hillman tripped one hurdle in the 400 metres, which meant that his time of 53.0 seconds could not be counted as a world record (the record had stood at 572 seconds since 1891). In addition, the race was run over hurdles that were too low at 76 centimetres instead of the normal 91,4.
En route to Greece for the 1906 Summer Olympics, Hillman was one of a half-dozen athletes who were injured by an enormous wave that washed over the deck of the ship.
He finished fifth in the 400 metres, his only event that year. Hillman"s time in the race was 55.3 seconds.
On April 24, 1909, Hillman and Lawson Robertson set a record that has never been equalled, running the 100 yards (91 m) three-legged race in 11.0 seconds. The track coach at Dartmouth College from 1910 until his death, Hillman advised hurdlers to swallow raw eggs, which he believed to be "excellent for the wind and stomach." He was on the Olympic track and field coaching staff in 1924, 1928, and 1932 Summer Olympics.
