What is really cool about the King and Queen of the Sea elite competition is that the men and women compete against each other via 2-person relay teams.

The teams have a choice who goes first and who is the anchor swimmer.

In the case the men go first, the women tend to hang out quite well in their draft. In the case that the men go last, the men tend to be able to catch up with the women quickly.

Around the 500m loop course in Copacabana Beach, the format makes for a fantastically exciting relay competition. The 3 km relay will be televised live this Sunday on TV Globo.
