100m Hurdles Pacing
How the world's best athletes pace the 100m Hurdles.
The Approach
The 100mH approach is 13.00m — slightly shorter than the men's 13.72m. Elite women use an 8-step approach and reach H1 in roughly 2.30–2.50s. The 8.50m inter-hurdle spacing (vs 9.14m for men) requires shorter, faster strides in the three-step pattern between barriers.
Tobi Amusan's 12.12 WR at the 2022 World Championships in Eugene came from an exceptionally fast approach and sub-1.00s hurdle units through the first half.
Clearance
Over the 0.838m (33-inch) barriers, elite air time is under 0.310 seconds per hurdle. Takeoff is roughly 2.0m out, landing about 1.0m past. That adds up to ~30m of the 100m race spent in the air. Even small reductions in clearance height translate directly to faster hurdle units.
The Run-In
Women have only 10.50m from H10 to the line, compared to 14.02m in the men's race. That makes the last hurdle clearance more important — a choppy H10 costs time with almost no room to recover. The best 100mH runners attack H10 and sprint straight through the finish.
