Surely, it can be said that hydrospeed is the water sport in which the participant is in greater contact with water. It consists of descending a river of white water using a small hydro-sled that covers the trunk of the participant, leaving the legs free in the water. In this way, the legs serve both as a helm and as a propellant. As in the case of rafting, for hydrospeed we need a minimum flow for navigation. This flow normally occurs between the months of May to September.
