HURDLE PACE CHARTS - 100, 110, 400
Success in the 400m hurdles is closely related to minimizing the number of strides taken and , as such, will depend on:
Speed Endurance (higher than 400m flat)
Hurdling proficiency (especially as fatigue increases)
Also an effective plan is needed.
An athletes race plan will depend on stride length, fitness, and ability to lead with both legs. It is preferable for the athlete to lead with the left leg on the bends. Generally the number of strides taken between hurdles increases throughout the race as fatigue sets in, but some can keep the same stride pattern throughout (Edwin Moses - 1976 Olympics - 13 strides between hurdles).
