KAILUA-KONA — An elite field of professional triathletes from around the globe are preparing to descend on Kailua-Kona, Hawaii for the women’s edition of the 2023 VinFast Ironman World Championship triathlon on Saturday. This will be the first time in history that the professional and age-group women are racing in a different location to the men, who raced on Sept. 10 in Nice, France.

The most iconic endurance event in the world will bring together over 50 of the world’s top professional female triathletes who will fight for a piece of the $375,000 USD female professional prize purse and the title of IRONMAN World Champion. Along with the professional field, over 2,000 age group athletes are registered for this historic event. Live race day coverage of the women’s 2023 VinFast Ironman World Championship triathlon can be viewed by visiting, www.ironman.com/live.

“The Ironman World Championship triathlon has a long and storied history in Hawaii, welcoming the world’s best female triathletes to Kailua-Kona for this edition of Ironman World Championship race that begins a new chapter,” said Andrew Messick, President &Chief Executive Officer for The Ironman Group. “The spotlight will be on women’s racing in Hawaii to witness the crowning of the 2023 IRONMAN World Champion and we are looking forward to a great day of racing.”

Reigning Ironman World Champion, Chelsea Sodaro (USA) returns to toe the line with bib No. 1 and the hopes of taking back-to-back Ironman World Champion titles. Sodaro’s win in 2022 marked the first win on debut by a female since 2007 and the first American since 1996. An advocate for mothers and female athletes globally, Sodaro has used her success to benefit the sport in many ways beyond the steps of the podium, donating her prize money from her second-place finish in the 2023 Athletic Brewing Ironman 70.3 Oceanside triathlon to a non-profit fighting for a safer community.

The 2022 Ironman World Championship runner-up Lucy Charles-Barclay (GBR) and third place finisher Anne Haug (DEU) will look to dethrone Sodaro for a chance at their own place in history. Charles-Barclay and Haug have won the Ironman 70.3 World Championship and Ironman World Championship triathlons respectively, making them fierce rivals for Sodaro. Charles-Barclay, the current record holder for the Ironman World Championship swim split in Kailua-Kona, has been runner up in the Ironman World Championship in 2017, 2018, 2019 and 2022 — leaving her undoubtedly with a desire to finally top the podium. A first-place finish in the Club La Santa Ironman 70.3 Lanzarote triathlon in March 2023 started Haug’s season strong and she hopes to finish in similar fashion in October.

Never to be underestimated at an Ironman World Championship race is competitor Daniela Ryf (CHE), a five-time Ironman World Champion, most recently in St. George, Utah in May of 2021. After a ninth-place finish in the 2023 Ironman 70.3 World Championship triathlon in Lahti, Finland and landing atop the podium for the eighth time in a row at the Ironman 70.3 Switzerland triathlon, she is hungry for more. She will be on the lookout for a sixth Ironman World Championship title which, if achieved, would tie her number of world titles with fellow countrywoman Natascha Badmann, and place her behind only Paula Newby-Fraser (ZIM) for most Ironman world titles by a female professional ever.

Kat Matthews (GBR), runner up in both the 2021 Ironman World Championship and 2023 Ironman 70.3 World Championship races, will be making an emotional return to the Big Island, after she was forced to withdraw from the competition last year after a serious bike crash which resulted in fractures to her skull, two vertebrae, and sternum.

After winning her second consecutive VinFast Ironman 70.3 World Championship title in Lahti, Finland in August, Taylor Knibb (USA) received an automatic qualification to the 2023 Ironman World Championship in Kailua-Kona. Knibb, whose mother is competing in this year’s event as an age-grouper has stated she will be in Hawaii and all signs point to her toeing the start line to make her full-distance Ironman debut. Knibb will be a contender after an incredible season which also saw her clinch the fastest ever Ironman 70.3 triathlon time in Lahti, as well as earning a spot in the 2024 Olympics following a test event in Paris, and taking the win at the Ironman 70.3 Boulder triathlon in June.

Others to watch at this year’s event include 2022 Ironman European Champion, Laura Philipp (DEU), 2023 Ironman European Champion, Sarah True (USA), Olympic Games Silver Medalist Lisa Norden (SWE), 2023 Ironman African Champion runner up, Fenella Langridge (GBR) and 2023 Ironman Asia Pacific Champion and Ironman Australia Champion, Kylie Simpson (AUS), among a host of others.

Beginning in the crystal-clear waters of Kailua Bay with the electrifying energy of the ROKA swim course creates an unforgettable 2.4-mile (3.8km) swim. Athletes start in the water and swim out-and-back in a clockwise direction facing small swells but otherwise mild and warm swim conditions. The swim starts and ends with a surge of excitement fueled by the crowds as athletes begin the first leg of their VinFast Ironman World Championship journey.

The 112-mile FulGaz bike course is renowned for its historic long sustained climbs, strong crosswinds, and exposed terrain beauty with lava fields on one side and the ocean coastline on the other. Starting from T1 at the Kailua Pier, the course makes its way directly out of Kailua-Kona and up to the Hawi turnaround where athletes will face challenging elevation gains and potential for crosswinds. Athletes will then return to town on the iconic Queen Ka‘ahumanu Highway. While there will be comfort in the captivating views this unforgettable course carries with it elevation gains of up to 5814 ft (1772 meters).

As athletes embark on the final leg of their race, the HOKA run course, an out-and-back jaunt takes runners past the spirited crowds on Ali`i Drive. The 26.2 mile (42.2km) run with elevation gains up to 1009 ft (307 metres) then brings athletes up Palani Road to the Queen Ka‘ahumanu Highway. This leads them to the long-awaited HOST Park at the National Energy Laboratory Hawaii Authority (NELHA) where races can be won or lost. From there the course contains rolling hills with intermittent steep stretches, followed by a triumphant return along the highway. The grand finale for athletes includes a victorious lap through downtown Kona, culminating in the exhilaration of crossing one of the most stunning and recognizable finish lines in triathlon.
