As USAT sanctioned events, BBSC Endurance Sports abides by standard rules issued to maintain consistency and order from race to race.  The rules include sections on USAT membership and rules of conduct for swimming, cycling, running and transition.  Also included are special sections on protests, hearings and appeals. The most commonly violated rules are indicated below:

USA Triathlon's Most Commonly Violated Rules

Wetsuits – USAT rules state that competitors may wear wetsuits if the water temperature is 78 degrees or lower. USAT rules also state that if the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards. If the water temperature is 84 degrees or above, participants may not wear wetsuits.

Helmets - Only helmets approved by the US Consumer Product Safety Commission (CPSC) may be used in USAT sanctioned events.  Helmets must be worn at all times while on your bike.  This means before, during and after the event.  
Penalty: Disqualification


Chin Straps - Chin straps must be buckled at all times when on a bicycle.  DO NOT unbuckle your chin strap unless you are off your bicycle.  
Penalty: Disqualification on the course; Variable time penalty in transition area only


Outside Assistance – No assistance other than that offered by race and medical officials may be used. Triathlons and duathlons are individual tests of fitness.  
Penalty: Variable time penalty


Transition Area – All equipment must be placed in the properly designated and individually assigned bike corral. The wheel of the bicycle must be down on the side of the assigned space. All participants must return their bicycles to an upright position in their designated bicycle corral. No person shall interfere with another participant’s equipment or impede the progress of another participant. All bar ends must be solidly plugged. No participant shall bring ANY glass containers into the transition area.  
Penalty: Variable time penalty


Drafting – Keep at least three bike lengths of clear space between you and the cyclist in front. If you move into the zone, you must pass within 15 seconds.  
Penalty: Variable time penalty


Position – Keep to the right hand side of the lane of travel unless passing.  
Penalty: Variable time penalty


Blocking – Riding on the left side of the lane without passing anyone and interfering with other cyclists attempting to pass.  
Penalty: Variable time penalty


Overtaken – Once passed, you must immediately exit the draft zone from the rear, before attempting to pass again.  
Penalty: Variable time penalty

Are you a USAT annual member?


You'll need to show proof of membership at check-in since our registration system doesn't automatically verify USAT memberships.


All non-members must sign the USAT waiver and pay a $15 one-day USAT fee during online registration - think of it as one-day race insurance (it's worth it).
