Brief Summary:
The proposed research study aims to investigate whether a gait modification training program to decrease peak braking forces during the stance phase of running will result in a reduction in impact loading and the incidence of running-related injuries among recreational distance runners.

Primary Outcome Measures :
  1. Peak Braking Force [ Time Frame: Baseline and 15 weeks ]
    The peak horizontal force applied in the posterior direction during the stance phase of running


Secondary Outcome Measures :
  1. Exposure time (Injuries) [ Time Frame: Baseline to 15 weeks ]
    From the start of the running program until the participant reports a running-related injury (injured runners) or until the end of the program (uninjured runners). Measured in hours of running exposure.

  2. Average Vertical Loading Rate [ Time Frame: Baseline and 15 weeks ]
    The average vertical loading rate during stance phase

  3. Step Frequency [ Time Frame: Baseline and 15 weeks ]
    The average number of steps per minute

  4. Step length [ Time Frame: Baseline and 15 weeks ]
    The average step length

  5. Heel to COM Distance [ Time Frame: Baseline and 15 weeks ]
    The horizontal distance between the heel and the vertical projection of the centre of mass at initial contact

  6. Vertical Displacement (whole body) [ Time Frame: Baseline and 15 weeks ]
    The vertical distance travelled by the centre of mass (COM) between consecutive foot strikes
