On July 20, 2025, the Long Beach Legacy Triathlon By Supertri, took place – mixing a celebration of sport, community, and philanthropy.
In 2024, Supertri (formerly Super League Triathlon) took on the operation of the Long Beach Legacy Triathlon in partnership with USA Triathlon. Building on last year, the 2025 event once again supported Children’s Hospital Los Angeles (CHLA), benefiting its Pediatric Cancer Research Program.
The triathlon exceeded its fundraising goal in 2025, raising US$715,000 and bringing the total raised to date to over US$19 million.
Under its new ‘By Supertri‘ branding in 2025, the triathlon welcomed athletes of all levels to compete in sprint distance, Olympic distance waves, and the Corporate Challenge, either individually or as part of a relay team.
Among the participants was James Amatruda, MD, PhD, Director of CHLA’s Cancer and Blood Disease Institute (CBDI), who raced to raise awareness and funds for paediatric cancer research.
Dr Amatruda leads clinical care, research, and education programs in paediatric haematology, oncology, and haematopoietic stem cell transplantation and cellular therapy.
He said, “The 2025 Long Beach Legacy Triathlon By Supertri is a critical fundraiser to support groundbreaking paediatric cancer research.
“With more than US$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.”
The Corporate Challenge saw participation from 21 teams and over 570 athletes, representing leading companies such as AEG, Amazon Studios, Ares Management, Canyon Partners, CHLA, Disney, Google, Medtronic, Netflix, Oaktree, Paramount, Skydance, SpaceX, and Warner Bros Discovery.
Disney earned the Champion of Hope award in the Entertainment Industry Division for top overall fundraising, while Canyon Partners took home the Champion of Hope award in the Corporate Division and earned recognition for highest average per person fundraising.
Warner Bros Discovery claimed the Tri Cup for fastest team performance. With Supertri’s second year in Long Beach, the Corporate Challenge increased fundraising by over 20% compared to last year.
Supertri honoured Los Angeles-area firefighters by offering free race entries in recognition of their heroic efforts during recent wildfires. The triathlon also introduced a new First Timer Program; a free athlete development initiative designed to ease intimidation and build confidence for newcomers.
The program included virtual educational sessions, a 12-week training plan, a private Facebook support group, race week guidance, and a dedicated swim start wave. Looking ahead, Supertri plans to expand both initiatives in the 2026 triathlon.
The event weekend also featured inclusive and family-friendly activities, including:
- The Athletic Brewing Beer Mile, a lighthearted relay or solo challenge combining running and beer;
- A Shake Out Run with coffee and bagels;
- The Splash & Dash for kids aged 6 to 15;
- “Ready. Set. Gold.” activities featuring Olympians;
- The Paratriathlon National Qualifier Series welcoming elite paratriathletes; and
- The Tot Trot, a race for children 12 and under.
Athletes also had the opportunity to compare their performance on Supertri segments, (4 km bike and 1.6 km run), against professional triathletes.
With a modified course enhancing the run and bike experience, and a growing community of supporters, the Long Beach Legacy Triathlon By Supertri is aiming to build momentum in the coming years.
