Requirements for the recognition of a world record are:
- The record must be achieved in an IUTA sanctioned race.
- The record must be achieved on measured tracks (bike and run) by an independent local authority. The measurement protocol must be handed over to IUTA.
- not a point-to-point race (elevation meters must accumulate to zero)
- There must be an electronic time system, which counts the number of laps and the time for each participant during the bike and run part. The event organizer has to provide the IUTA with the laps and times of the athlete, who achieved a new best time.
- a negative doping test of the corresponding athlete, executed according to the rules of WADA and to the rules of IUTA
