A proposal is submit for the classification referring to the way in which triathletes carry their bicycles into the boxes during the first transition. This area must be covered on foot carrying the bicycle next to you. The demonstration was made up by the participants of three Spanish Championships and age groups of different distances and types (407 triathletes). They were recorded on film from the time they took their bikes down and moved through the boxes. The purpose is to determinate how the binomial triathlete-bicycle was moved into the transition area, (hold-riding), in other words, in which part of the bike they put their hands. It’s the moment in which, having everything necessary to peddle, the triathlete picks up their bike, and travels through the transition area carrying the bike next to them as fast as possible. It was concluded that there were four habitual types of hold-riding bikes in the transition area.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
