USA Triathlon sanctioned

What sanctioning means.

The event follows a national framework for safety planning, fair competition, membership and rule enforcement. Sanctioning does not eliminate every possible risk.

Safety Review

Event management documents courses, medical support, emergency procedures, volunteers, permits and water safety.

Fair Competition

Athletes race under one recognized rulebook covering conduct, equipment, drafting, transition, penalties, results and appeals.

Membership & Coverage

Each participant must hold an eligible annual USAT membership or purchase the applicable one-day membership during registration. The membership fee is collected for USA Triathlon, not the race.

Which rules apply to you? General, transition, cycling, conduct and applicable finishing rules apply to everyone. Swim rules apply to Triathlon and Aquabike. Run rules apply to Triathlon and Duathlon. Relay, adaptive and category-specific rules apply when relevant.

Know these before racing

Your bicycle must be roadworthy with working brakes, plugged handlebar ends and no loose or unsafe equipment.

Respect Others and the Venue

Conduct

Abusive or dangerous conduct is prohibited. Do not intentionally discard bottles, clothing, nutrition, equipment or trash outside approved areas.

Texas City bike course

The approximately 15-mile course is longer than 20 kilometers.

Under the current USAT schedule, a blue-card drafting penalty is one minute and a yellow-card cycling penalty is 15 seconds for this distance. Report to the designated penalty area when instructed. Two or more blue cards may result in disqualification.

Triathlon & Aquabike

Wetsuit rules & water temperature.

The official race-morning water temperature determines wetsuit status for this non-National USA Triathlon age-group event.

60.6°F and Below

Wetsuits Mandatory

Athletes must wear an allowable wetsuit. Race management and the Head Referee may shorten or cancel the swim when conditions create a safety concern.

60.7°F–78.0°F

Wetsuits Permitted

Athletes may choose whether to wear a wetsuit and remain eligible for applicable results, rankings and awards.

78.1°F–83.9°F

Allowed, but Awards Ineligible

Athletes may wear a wetsuit but are not eligible for age-group awards or USAT rankings unless an official variance applies.

84.0°F and Above

Wetsuits Prohibited

Wetsuits and garments containing prohibited neoprene, polyurethane or other rubberized material may not be worn.

How the Official Temperature Is DeterminedWater temperature is measured race morning using USAT procedures, generally about one hour before the start and at multiple course locations.

Wait for the Race-Morning AnnouncementBring your wetsuit if you may use it, but do not assume it will be permitted or award-eligible before the official announcement.

Neoprene Includes More Than Full WetsuitsWetsuit shorts, buoyancy pants, neoprene garments and other rubberized clothing count as wetsuit equipment. Maximum thickness is five millimeters.

Safety May Change the DeterminationThe Head Referee may modify wetsuit use, shorten the swim or cancel it because of water quality, waves, currents, wind or temperature.

Officials & enforcement

How penalties work.

The response to a violation may include an instruction to correct it, a time penalty or disqualification.

Warning & Amend

Correct the violation immediately when instructed. Failure or refusal may lead to a stronger penalty.

Yellow Card

Used for certain position, equipment, transition or conduct violations. The time penalty depends on the rule and distance.

Blue Card

Used for drafting violations. Report to and serve the penalty at the designated cycling penalty area.

Disqualification

Serious, dangerous, uncorrected or repeated violations may result in removal from competition.

Always follow the official’s instructions. Do not argue while on course. Handle questions after finishing through the established review or appeal procedure.

Texas City requirements

Race-specific rules.

These requirements apply in addition to USAT rules. Updated briefing or race-day safety directions take priority when conditions change.

Assigned Swim Cap

Triathlon and Aquabike athletes must wear the race-issued cap assigned to their swim wave throughout the swim.

Wetsuit Determination

Eligibility is based only on the official race-morning temperature and applicable USAT rule. Do not rely on unofficial readings.

Athlete-Only Transition

Only registered athletes and authorized personnel may enter restricted transition. Family and spectators may not enter to carry equipment or help set up.
