110m100m

110m100m is not an official event in major track and field competitions. It is a compact notation sometimes used in schedules, result sheets, or training plans to reference two classic sprint disciplines together: the 110 metres hurdles (men) and the 100 metres dash (sprint) for both sexes. In practice, 110m typically denotes the hurdles event, while 100m denotes the straight sprint.

The two events differ in several respects. The 110 metres hurdles features ten hurdles and requires a combination of speed and technique, with the hurdle height higher for men (and different hurdle spacing) than in the 100m dash. The 100 metres dash is a pure sprint over a straight track with no obstacles and is contested by both men and women at the same distance, though with separate records and championships. World records associated with these events are separate: the men’s 110m hurdles world record is 12.80 seconds, set by Aries Merritt in 2012, and the women’s 100m dash world record is 10.49 seconds, set by Florence Griffith Joyner in 1988.

In training contexts, 110m/100m may appear together to indicate a session that includes both a hurdle sprint and a flat sprint, or in decathlon and other multi-event schedules where both events are part of the program. The term itself does not denote a single competition or standard results line; rather, it reflects a combined reference used in documentation.
