Our races which offer Clydesdale (men) and Athena (women) categories base the rules on the competitive rules from USA Triathlon.
Rules regarding weight class division: “In events where a weight class division is offered, the minimum weight shall be 220 pounds for men and 165 for women monitored by the event organizer. The weight class age categories for men and women shall be 39 years of age and under and 40 years of age and over. Participants are not eligible to compete in a weight class division and in an age group division in the same event”.
Many Epic Races triathlons offer Athena and Clydesdale. USAT also offers an Athena and Clydesdale national competition which location is determined bi-annually.
