Swim with a Purpose: CLASH Endurance Announces New Charity Swim Events with Swim Across America

1-Mile Swim and 100M Dolphin Dash Take Place December 7 at Daytona International Speedway

CLASH Endurance® and Swim Across America are thrilled to announce a new charity swim in Lake Lloyd, located in the infield of the iconic Daytona International Speedway® on Sunday, Dec. 7, 2025. Participants of all ages will have the opportunity to swim alongside notable Olympians in an inspirational one-mile swim or a 100-meter Dolphin Dash with fundraising for critical cancer research as their top priority. Funds raised will support Swim Across America’s breakthrough pediatric cancer grants with its beneficiaries and CLASH Endurance’s philanthropic partner The NASCAR Foundation.

Swim Across America, founded in 1987, hosts 24 annual open-water swims from Nantucket to under the Golden Gate Bridge, and hundreds and pool swims each year that fund cancer research and patient programs, raising more than $100M to date. Swim Across America has funded transformative trials that led to the FDA-approved immunotherapy cancer medications Keytruda, Opdivo, Yervoy and Tecentriq. The organization has also supported Memorial Sloan Kettering’s landmark trials including the recent Phase II clinical trial published in The New England Journal of Medicine showing an 80% success rate treating MMRd cancers with immunotherapy alone. Swim Across America also recently awarded the first-of-their-kind gene editing innovation grants to Alliance for Cancer Gene Therapy and Dana-Farber Cancer Institute to advance safer, more effective targeted treatments.

“Swim Across America, CLASH Endurance and The NASCAR Foundation joining together makes so much sense as The NASCAR Foundation helps so many kids who are battling cancer,” commented Rob Butcher, CEO of Swim Across America. “To have a Swim Across America charity event in Daytona on the CLASH Endurance Family Weekend means we will make even bigger waves together in the fight against cancer.”

The NASCAR Foundation is a leading charity that works to improve the lives of children who need it most in NASCAR racing communities through the Speediatrics Children’s Fund and the Betty Jane France Humanitarian Award. Serving as a designated 4-Star Charity by Charity Navigator for its strong financial health and ongoing accountability and transparency, it has contributed more than $50 Million to impact the lives of more than 1.7 million children nationwide since 2006.

“We are excited to be a part of the new Swim Across America swim during the CLASH Endurance weekend at Daytona International Speedway. We truly appreciate the many years of support from our friends at CLASH, and it is a privilege to team up again to help improve the health and well-being of kids across the country and in our race communities,” said Nichole Krieger, vice president and executive director of The NASCAR Foundation.

On December 7, when hundreds of swimmers and volunteers dive into Lake Lloyd, one-mile swimmers will be required to raise at least $400 by event day; swimmers under 18 will raise a minimum of $200; Dolphin Dash participants can register for $50 and have no fundraising minimum. To register as a swimmer or a volunteer, visit swimacrossamerica.org/daytona.

CLASH Endurance CEO Bill Christy says, “We are proud to collaborate with Swim Across America which continues to make a lasting impact in the cancer community. This is a cause that has touched all our lives, and we are honored to further support the fight at one of our flagship event weekends.”

Each December when much of the country battles snow, more than 3,000 participants ranging in age from four to 80+ will take on the speedway through a variety of events including a 5K, kids’ triathlon, duathlon, aquabike, triathlons, Test Track and Redline Relay. CLASH Endurance strives to provide a festival-style weekend, which in addition to free activities for spectators and athletes alike, include a wellness expo, food trucks, beer/wine garden and much more. The weekend kicks off with a festive “Jingle Jog 5K” on Friday evening with a start and finish at ONEDaytona. Participants, including those in jogging strollers, will experience Florida’s “Magic of Lights” holiday display taking them under the iconic grandstands of the speedway. The Swim Across America 1-mile swim and Dolphin Dash will help cap-off the weekend on Sunday, December 7.

“We have swum in some incredible venues and Daytona International Speedway is certainly one of the most iconic,” noted Olympic swimmer and Swim Across America Ambassador Rowdy Gaines. “To have a Swim Across America charity swim in Daytona is going to be extra special – I will definitely be there!”

17-Year-Old Marathon Swimmer Maya Merhige Conquers New Zealand’s Cook Strait, Continuing Her Mission to Make Waves to Fight Cancer

Berkeley, California Resident is one of the Youngest in History to Complete the Triple Crown of Open Water Swimming and Has Raised More than $125,000 for Cancer Research through Swim Across America

Maya Merhige a 17-year-old marathon swimmer from Berkeley, California, on March 14, 2025, successfully swam New Zealand’s Cook Strait, a 22 km (13.67 mile) body of water and one of the world’s most challenging open water swims. This latest achievement for Merhige comes just eight months after she successfully swam the English Channel in July 2024, becoming one of the youngest swimmers in the world to achieve the Triple Crown of Open Water Swimming. The completion of the Cook Strait makes this her tenth marathon swim — all which have been done to raise funds for cancer research with the nonprofit Swim Across America. Throughout her years of swimming and making waves to fight cancer, Maya has raised an incredible $125,000!

Merhige completed the Cook Strait swim in 14 hours, eight minutes and 36 seconds. At 17, she joined the ranks of one of the youngest swimmers to successfully conquer this formidable strait. Accompanying Merhige on this journey and on her support boat was her father Chris Merhige, her official timekeeper, friend and open water coach Kelly Gentry, and her godparents Geoff Tennican and Jen Durning, who have been steadfast supporters of Maya’s and who have donated more than $18,000 to her cause to make waves to fight cancer for the nonprofit Swim Across America, the beneficiary of Maya’s swims. Their presence on the support boat provided invaluable encouragement throughout the swim and helped keep Maya going by relaying uplighting and inspiring messages from Maya’s family and friends all around the world who were following her progress.

The Cook Strait is known for its rough and unpredictable water, high winds and abundant marine life. Situated between the North and South islands of New Zealand, the Cook Strait connects the Tasman Sea with the South Pacific Ocean. Both shores are lined with steep cliffs which can create a wind tunnel effect. The strong gusts of wind and tidal flows make it one of the roughest and most unpredictable stretches of water in the world. The challenging conditions have attracted numerous swimmers, many of whom have failed to make the crossing and several who have succeeded. 

The water in the Cook Strait during Maya’s swim was a bit rough with 15-to-25 knot winds and 1 metre swells and the water was a chilly 60 degrees with the air temp only 59 degrees fahrenheit. According to marathon swimming rules, Maya swims with only a bathing suit, swim cap and goggles. “This was one of the gutsiest swims I’ve ever seen, and was according to some folks on the boat too,” noted Maya’s father Chris Merhige, who was on the support boat traveling alongside Maya during her swim.

“Swimming the Cook Strait was a hard, but incredible experience,” Maya Merhige said. “The jellyfish stings, unpredictable currents and wind presented unique challenges, but knowing that my efforts contribute to cancer research kept me motivated. Having my godparents by my side meant the world to me—they have been some of my strongest supporters, always believing in me and helping to make these swims possible.”

Completing the Cook Strait brings Merhige closer to completing the Ocean’s Seven Swims – the most challenging open water swims in the world. Since 2020, she has completed the Catalina Channel, Molokai Channel, English Channel and Cook Strait – with still to come the North Channel, Tsugaru Strait and Strait of Gibraltar.

Merhige’s previous accomplishments include becoming the youngest woman to swim the 20-mile Catalina Channel at just 14 years old, completing the 28.5-mile Manhattan 20 Bridges swim at 15, and crossing the English Channel at 16, earning her the Triple Crown of Open Water Swimming.

Merhige’s commitment to open water swimming began at age nine when she joined her first Swim Across America – San Francisco open water swim, where she swam with Team Susan Survives! in honor of a family friend and three-time cancer survivor, Susan Helmrich. Since then, she has participated in the annual swim, raising more than $125,000 for pediatric cancer research with Swim Across America – San Francisco’s local beneficiary UCSF Benioff Children’s Hospitals.

While raising funds for cancer research and new treatments in support of friends and family members battling cancer has been her inspiration for swimming, writing their names on her swim cap to bring them on the journey with her, Maya has had her own personal health challenges, including discovering a benign pancreatic tumor in 2023 after a ski accident. She has had some ongoing health challenges stemming from the issue and has had her own hospital stays and surgeries, which have only deepened her empathy for cancer patients and strengthened her resolve to support cancer research and help fund new and better treatments.

This fall, Merhige will be starting her freshman year at college, but still hopes to participate in the annual Swim Across America – San Francisco open water swim on September 21, 2025, marking her ninth year swimming in the event.

Swim Across America’s grants have helped support the research and clinical trials for FDA approved immunotherapy medicines: Keytruda, Opdivo, Yervoy, and Tecentriq. Swim Across America is also a grant funder of the successful clinical trial at Memorial Sloan Kettering that was published in The New England Journal of Medicine and showed a 100 percent success rate in treating patients in a phase 2 clinical trial for advanced rectal cancer with dostarlimab, an immunotherapy treatment produced by GlaxoSmithKline. Swim Across America awards grant to more than 60 projects each year and there are ten named Swim Across America Labs at major institutions.

Natalie Thompson Makes Waves: How One Nantucket Family Lives the Swim Across America Mission

Most Swim Across America participants wear their SAA swag with a sense of pride of making an impact in their community. For Natalie Thompson and her family in Nantucket, Massachusetts, it’s more than just an event — it’s a way of life.

“Swim Across America – Nantucket gear is a badge of honor on this island. We swim for the people we see everyday — our neighbors, our friends, and our family — so we can make their fight easier,” said Natalie.

Swim Across America – Nantucket gives grants to on-island cancer treatment and care at Nantucket Cottage Hospital and Palliative and Supportive Care of Nantucket. It also supports glioblastoma research at Mass General Cancer Center in Boston. The unique offering of on-island care allows patients fighting the toughest battle to remain close to home while receiving outstanding treatment.

When it comes to SAA gear, Natalie and her family have plenty. Since 2012, she has participated in the event — in every and any capacity — alongside her wife, Cassie, and their two sons.

“I’ve been part of the setup crew, the breakdown crew, an angel swimmer, a 4-miler… whatever I can do, I do,” said Natalie. “My wife has always volunteered, and now she runs the Falmouth Road Race to support our swim. SAA is just part of our lives. We do it as a team to support our amazing community.”

Natalie first joined SAA-Nantucket to honor her grandmother, who fought breast cancer. As the years went by and Natalie remained involved, cancer would hit close to home not once, but twice more.

“June 2019 changed why I swim for the rest of my life. My wife was diagnosed with ocular melanoma at 33. We had two young boys at the time, and suddenly, we were facing cancer head-on,” she shared.

Natalie swims the 4-mile course while her wife, Cassie, kayaks beside her.

“Eight hours after she was diagnosed we attended a Swim Across America event and I knew we had a support system like no other. No one at the event knew that night of her diagnosis but I left having hope that we would make it through it all. This was the first summer I participated in the 4 mile swim and it was even more impactful having my wife as my kayaker.”

Less than a year later, Natalie’s family was hit with more devastating news.

“In March 2020, our world was rocked again. My dad was diagnosed with stage 4 renal cancer,” Natalie said.

“As soon as I heard the news, Jill Roethke and Jim Pignato, SAA-Nantucket co-event directors, were my first call. The world was shutting down due to COVID, and my dad needed tests to begin treatment. They got me connected to the right people, and in that moment, I knew our family had endless support from our Swim Across America family.”

For as long as SAA-Nantucket is around, Natalie and her family will be there, supporting the mission and their community — a value she’s proud to pass on to her sons.

Natalie and her boys love to match in SAA gear!

“SAA’s impact on the Nantucket community as a whole means that no one fights their cancer battle alone. We are a community on a little island ensuring that cancer patients spend their invaluable time with their families and friends instead of countless hours traveling for treatment elsewhere.”  

“My kids have grown up attending the event, and it’s incredible to teach them about this special support system. They know I swim for their grampie and mom. It’s a special moment every year when I finish the 4-mile swim to have my kids see me finish.”
