The National Officials Program is a source of pride for USA Triathlon and all the officials who honorably volunteer their service to our sport and the National Federation.  It is the goal of the Officials Program to provide the highest quality service with experienced and professional officials to officiate USA Triathlon sanctioned events including triathlon, duathlon, aquathlon and other multi-sport events.

Below is the updated ruleset for 2023 and beyond. These documents represent the most current ruleset, policies and procedures. Please use these documents when referring to USA Triathlon's multisport rules.

2023 Ruleset 

Effective Wednesday, March 15, 2023

Note: As of March 2023, USA Triathlon will align with World Athletics on legal running shoe specifications:

  • The sole must be no thicker than 40mm.
  • The shoe must not contain more than one rigid embedded plate or blade (of any material) that runs either the full length or only part of the length of the shoe. The plate may be in more than one part, but those parts must be located sequentially in one plane (not stacked or in parallel) and must not overlap.
