The Great Relay is the biggest, longest pool-based relay competition in the United States. Teams of 8 or more swimmers see how fast they can finish 5000 yards or meters. There are many different types of teams that can compete to be ranked and receive recognition nationally: different ages, types of swim teams (summer league, high school, club, etc), pool lengths, and more.

The Great Relay is critical in helping the Trident Swim Foundation fund and support their inner city Swimmer Scholar program. The Great Relay encourages fun competition in swimming and raises awareness of the need for better access to swim lessons, competitive swim teams, and academic support in inner cities.
