The Long Beach Legacy Triathlon proved to be more than a race on July 20. The event brought together more than 1,700 participants and raised $706,650 for Children’s Hospital Los Angeles to support its Pediatric Cancer Research Program.
The event was presented by Supertri, the global leader in short course triathlon. The Long Beach Legacy Triathlon used the weekend to host a slew of activities for participants of any age and experience to participate in.
The weekend included a Sprint Distance, Olympic Distance, Corporate Challenge and a Kids Splash & Dash Day on July 19. The Long Beach Legacy Triathlon opens the opportunity for participants to run on their own or as a relay team, making its scenic course accessible for any participant.
After a historic wildfire season in Los Angeles, Supertri chose to honor local firefighters and offer them free race entries in an effort to thank them for their service this year.
“We are thrilled to announce a special initiative to honor the brave firefighters of the Los Angeles area,” said Michael D’hulst, CEO and Co-Founder of Supertri. “Their heroic efforts in combating forest fires earlier this year have been truly inspiring. As a token of our appreciation, we are offering free race entries to the Legacy Long Beach Triathlon. This initiative is our heartfelt thank you to the LA-area firefighters for their unwavering dedication and hard work in protecting our community.”

The event brought together a larger community for a greater cause. Amongst the participants was James F. Amatruda, M.D., Ph.D., Director of the Cancer and Blood Disease Institute and Chief of the Division of Hematology-Oncology at CHLA. Dr. Amatruda leads clinical care, research, and education programs in pediatric hematology, oncology, and hematopoietic stem cell transplantation and cellular therapy.
“The 2025 Long Beach Legacy Triathlon By Supertri is a critical fundraiser to support groundbreaking pediatric cancer research in the Cancer and Blood Disease Institute at Children’s Hospital Los Angeles,” said Amatruda. “With more than $19 million raised through annual triathlons since 2007, every participant helps propel our efforts to develop safer and more effective cancer therapies and get the right treatment to children in need. I am thrilled to be part of the CHLA Triathlon Team this year, and we thank you for joining us in this exciting event.”
Over 570 athletes represented 21 teams in this year’s Corporate Challenge. Companies such as Netflix, Amazon Studios, Paramount, Disney, CHLA, Google and SpaceX took place in this year’s event.
Canyon Partners earned the Champion of Hope award in the Corporate Division and earned recognition for highest average per person fundraising. Disney was awarded the Champion of Hope award in the Entertainment Industry Division for leading in overall fundraising, and Warner Bros Discovery claimed the Tri Cup for fastest team performance.
The Long Beach Legacy Triathlon was a great success this year, both in fundraising and participant turnout. As the Triathlon continues to expand in the coming years, it becomes a more inclusive and impactful weekend for all.
