To build up the locomotor profile of a racehorse, two indicators must be analysed: stride length and stride frequency. In racing, if the stride becomes longer it will logically be more difficult to sustain a high pace. Likewise, when you want to accelerate the pace of your strides, it becomes difficult to maintain a long stride. Finally, pace is often directly correlated with endurance: a high pace is difficult to sustain over a long period of time and will therefore hinder high endurance.

Thanks to these two indicators, it is possible to identify two theoretical profiles according to the type of race: the sprinters who will be oriented towards short distance races and the milers or stayers who will be engaged in long distance races.

The sprinters will have a high stride-rate, which they develop over long distances, allowing them to reach their maximum speed quickly. 

Milers and stayers will have a low stride rate and a high amplitude that allows them to develop their speed over the distance.

 In this example, we notice that the average stride rate of the horse at 60km/h is less than 2.4.
