The Competitive Rules are intended to provide for the orderly and consistent administration of events sanctioned by USA Triathlon and are not designed to establish standards of care for the safety of participants or other persons. Every participant, official, volunteer and spectator should consider all safety issues and make related decisions prudently without reliance upon the Competitive Rules.

USA Triathlon makes no express or implied warranty, guarantee, or representation regarding the degree of safety, which may or may not result from compliance with the Competitive Rules.  Examinations or inspections of equipment at sanctioned events are undertaken solely to monitor compliance with the Competitive Rules and do not guarantee or ensure safety from personal injury or property damage.  The safety of race equipment is the sole responsibility of each and every participant.
