The full size (long course) running track is 60 m long, the surface suitable for running bare foot. At the end of the running lanes there are transitional target discs, continuous with a 50m swimming pool (the short course is 30m running and 25m swimming). The takeoff for the dive must be with the foot within the target disc. The winner is the first to touch the wall at the end of the swim.
No false start, or the Earthlete shall be disqualified.
The Earthlete comes to the start line as the whistle blows to start the race, to a crouch or block start.
The starter will command “Earther’s take your mark” and a signal sounds to start the race.
The earther must remain within their lane marking from start to finish of the race so as not to be disqualified.
The transition launch must be with one foot within the marked outer disk, the inner disc is for the Earthlete to transition safely. If the foot is outside of the outer disc the competitor will be disqualified.
The earthlete executes a dive and upon entering the water undulates to a distance no greater than 15 meters (short course) and 20 meters (long course) meters from the transition pad.
The Earthlete swims the remaining distance using freestyle.
The race is completed for time with a wall touch, so as not to be disqualified.
The Earthlete shall exit the pool after the last competitor has finished the race.
