Major League Triathlon recently announced the third-year league will return to Atlantic City, New Jersey on July 21.

The triathlon will once again consist of 32 of the best professional triathletes in the world. Each athlete will swim 300 meters in the Atlantic Ocean, bike 4 miles and run 1 mile on the historic Atlantic City Boardwalk.

This triathlon is unique because of its shorter length and faster pace. Announced in June of 2017, this format of racing, known as Mixed Team Relay, will make its debut as an Olympic event at the Tokyo 2020 Olympic Games. Many competitors at the Atlantic City event will compete in the 2020 Olympics.

Major League Triathlon is the first and only professional triathlon league in the United States. The best male and female athletes in the world compete against each other in a unique swim, bike and run team event. Held in major cities across the country, MLT pros compete in pop-up stadiums, allowing for a spectator experience unlike anything seen in the sport.

“We are incredibly excited to continue working with the Atlantic City Sports Commission. This was by far the most unique and exciting venue in our lineup last season and our athletes are eager to return,” said Daniel Cassidy, chief executive officer for Major League Triathlon. “It isn’t often that you see 32 of the world’s best professional athletes biking and running on the iconic Atlantic City Boardwalk in the heart of summer.”

During the MLT event in Atlantic City, the Atlantic City Waves, Atlantic City’s own professional triathlon team, will play host to seven additional MLT professional teams. The teams will once again face off in a super sprint mixed relay format. Each athlete will complete a quick swim, bike and run and then tag their next teammate in line. The first team to have all four athletes cross the finish line will win.

This event is free and open to the general public.
