History Sports Triathlon Para-Triathlon became part of the Paralympic programme for the first time at the 2016 Rio de Janeiro Games. Athletes compete in three disciplines: 750m of Swimming, 20km of Cycling followed by a final 5km run. For the Cycling section of the race, athletes may use a tandem bicycle, handcycle or bicycle, while a wheelchair may be used for the final 5km run to the finish line. Athletes who have visual impairments can be assisted by a guide without giving the athletes any unfair advantages. British athletes currently use the same classification system at both national and international level, which consists of six classifications, but this is likely to change.
