How many hurdles (flights) are there in the men's 110 m hurdles race?

In the men's 110 m hurdles, each athlete must clear 10 hurdles (called "flights") placed at fixed intervals along the straight track.

Layout of the men's 110 m hurdles:

• Distance from the start to the first hurdle: 13.72 m.
• Distance between hurdles: 9.14 m.
• Distance from the last hurdle to the finish line: 14.02 m.
• Height of each hurdle: 1.067 m (42 inches).

All the hurdle races in athletics have 10 hurdles:

• Women's 100 m hurdles: 10 hurdles, each 0.838 m high; 13 m to the first hurdle, 8.5 m between hurdles, and 10.5 m from the last hurdle to the finish.
• Men's 400 m hurdles: 10 hurdles, each 0.914 m high; 45 m to the first hurdle, 35 m between hurdles, and 40 m to the finish.
• Women's 400 m hurdles: 10 hurdles, each 0.762 m high, with the same spacing as the men's 400 m hurdles.

Rules:

• Athletes may knock down hurdles without being disqualified, but they must not deliberately knock them down with a hand or foot, trail a leg alongside the hurdle (below the top), or run outside their lane.
• Each athlete must stay in his or her own lane throughout the race.

Other facts:

• The men's 110 m hurdles has been part of the Olympics since 1896, and the women's 100 m hurdles since 1972 (replacing the 80 m hurdles).
• India's Jyothi Yarraji holds the national record in the women's 100 m hurdles and won the Asian Championships title in 2023 and 2025.

In the 400 m hurdles, P. T. Usha finished fourth at the 1984 Olympics.

The 3000 m steeplechase is a different event, with 28 barrier jumps and 7 water jumps.

Why not the other options?

• ✗8 is not the number of hurdles in any standard hurdles race.
• ✗12 and 15 are also incorrect; all standard hurdle races use 10 hurdles.
