Summary Kinematic parameters were measured from horses competing in a CCI*** 3‐day event The horses were filmed during the first and third horse inspection. This provided a repeat sample on 16 horses. The horses were filmed using a panning lateral S‐VHS video camera (50 Hz). Spatial measurements were taken for mean ± s.d. 5.66 ± 0.92 strides for the first inspection and 5.05 ± 1.27 for the third inspection. Within the calibration zone, data of the horses accelerating and obtaining a constant velocity were collected. The horses trotted with a higher mean velocity during the third inspection (0.26 ± 0.05 m/s, P<.001). During the third inspection the horses trotted with a shorter stride length (0.193 ± 0.03 m., P<.001) and stride duration (31 ± 42 m/s, P<.001). The third inspection was characterised by a decrease in retraction percentage for both the forelimbs (3.69 ± 2.39%, P<.001) and the hindlimbs (2.48 ± 2.16%, P<.001). However, no significant difference was found between the 2 inspections for other temporal parameters when measured as a percentage of stride. It is proposed that the event horses trot with a decreased stride length and duration during the third horse inspection but maintain a consistent temporal relationship.
