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.

Top Questions For… Top San Francisco Fundraiser Steve Barbour

This weekend, the SAA family will take to the waters in the San Francisco Bay for our final swim. The annual swim is set to raise over $450,000 to benefit the UCSF Benioff Children’s Hospital and Children’s Hospital Oakland Research Institute!

Steve Barbour joined the SAA – SF family in 2011, and took no time to get his feet wet (pun intended). He has been one of the top fundraisers for the swim in each of his three years participating, and those who know him can attest to the warmth he exudes, even if the Bay is chilly! We caught up with him to chat about his tribute team, the secret to successful fundraising and the taking a dip under the Golden Gate.

  1. Tell us a little about who or why you’ve gotten involved with SAA.

I started swimming 3 years ago to get back in shape and help manage stress. I happen to swim at the same facility as Susan Helmrich, who is a co-chair of the SF swim, and she invited me to join her team. Seemed like a good idea at the time.

  1. Are you a natural swimmer? Why choose a distance swim instead of a run or bike?

I’m not a natural swimmer although my younger brother Dave was competitive and a Laguna Beach lifeguard for many years. At first I thought I could train my way up to be competitive with him although he is 10 years my junior… big mistake! But now we can distance swim together, although he has to hold back and swim at maybe 65%. He did the event last year and it was great. Then we swam Alcatraz the next morning!

  1. Tell us about your team and the people swimming with you.

I swim on Team Susan Survives. It’s a fairly large group, as Susan knows everyone. You can’t help but be inspired by how she has managed her challenges (3 time survivor).

  1. You’re a top fundraiser for the San Francisco swim! What’s your secret?

I’ve been very fortunate in my career. I’ve worked at a large company for many years (Nestlé), and my wife and I have moved with the Company a number of times so we have a fairly large number of friends, both in and outside the company, that are happy to help out. The real secret is starting early, say early June, and following up occasionally, as often times the first or second email is just lost as people are so busy. It does take time… but it is obviously worth it! I also think I have an easier time because this is the only event that I ask for support from my family, friends and contacts.

  1. Would you rather: swim 3 miles on a sunny day or 1 mile with a shark tailing you?

I’ll take the 3 miles every time!!!

  1. How have you been touched by cancer?

We lost my Uncle Les way too early from brain cancer… he was only 55. And a friend and co-worker for over 25 years lost his son, David Stroud, to cancer. That was very tragic.

  1. What do you remember from your first SAA swim that keeps you coming back?

That was the year David Stroud passed away… just before the event…the kid was unbelievably tough, and I still get emotional when I think about it.

  1. What makes the SAA – San Francisco swim so unique?

With all due respect to Chicago, New York, and the other locations, you can’t beat swimming from under the Golden Gate into Crissy Field! The views and the location cannot be beat. It is iconic!!!

  1. What makes Swim Across America special?

I have really enjoyed all the people I have come into contact with in the SAA organization as well as the local event leaders. It is also important that SAA does a good job managing their cost structure so that the bulk of the funds raised go to the intended purpose.  And obviously, I enjoy swimming in the Bay.

  1. What is your favorite time of day to swim? Why?

I like to swim early… I used to hit the water at 6:30 AM, but now that I am retired, I start an hour later, and spend more time in the whirlpool! It’s a great way to start the day!

Newbie’s Guide to Open Water Swimming

Pink cap arms up

Open water swimming is a bit different than a dip in the pool. Mother Nature doesn’t always keep her bathtubs at a balmy 80 degrees, and when the only walls are walls of waves, an open water swim can seem intimidating. But we at Swim Across America know from experience that there’s nothing like the soft sound of rolling waves, the energy of becoming one with the water, and the accomplishment of crossing that finish line on the beach.

United by our commitment to the fight against cancer, we take pride in all who contribute to the cause. For those that swim with us, or are considering getting their feet wet, we’ve compiled some basic tips for taking the plunge!

Getting Ready

Believe it or not, most open water swimmers do a lot of training in pools. When prepping for an event, make sure you can swim at least the distance of the course comfortably. You can also practice a couple things that will help you once you get out onto the open seas:

  • Practice breathing to both sides. Bi-lateral breathing not only balances your body in the water, it can help you keep the sun from bothering your eyes, sight the shore without lifting your head, and avoid splashes from fellow swimmers.
  • Learn a few high-elbow drills. Waves in the open water can impede your recovery, so working on a stroke with a high elbow can help you to better extend your pull and catch the water.
  • Practice sighting. Since visibility can be low, you’ll need to sight where you’re swimming and establish a rhythm of lifting your eyes to see. Try the Gator Drill:
    • Close your eyes while your face is in the water, and lift your eyes slightly like an alligator to sight where you are in the pool while you practice. Get used to a rhythm of sighting (every 5 strokes, or more if you feel you can stay straight.) Be careful once you get close to the wall!!

Before race day, it’s helpful to have practiced even a little in the open water. If you can, swim part (or all!) of the course- it’s a great way to get comfortable.

The Main Event

Now is the time to trust your training and kick some open water butt! The most important thing to remember before your first open water event is to keep your composure. Panic can be a worse enemy than a riptide. Relax and remember not to fight the water, and your swim will be a piece of cake!

In case you’re so nervous you’re practically wetting your wetsuit, here are a few last-minute tips.

  • Nervous about your goggles coming off? Put them on before your cap, so they’re snugly underneath it. They won’t budge.
  • Nervous about getting run over by the pack? Position yourself on the outskirts of the swimmers before the start, and avoid the chaos from the beginning.
  • Starting to get nervous during the swim? Don’t forget- if you need to roll over and do some backstroke, mix in some breaststroke, or even just float for a while, that’s perfectly fine. Do what you need to re-focus and relax, then get moving again!
  • Get in a good warm-up. Whether it’s in or out of the water, a good warm-up will get you psyched for an event and physically ready as well.

Think you can handle more? Here are a couple other tips for the more confident open water newbie:

  • If you can’t see a buoy or a landmark you’re using to spot, follow the pack. Usually they’ll be going in the right direction. Check periodically to re-situate yourself and find your landmark.
  • Periodically breathe to the side that the shore is on in order to spot yourself and lift your head less.
  • Packs of swimmers can form and can get strung out, or split up, throughout the course. Make a plan! Figure out if it’s beneficial for you to get into a pack, and if so, where it’s best for you to position yourself within it, and what to do if you get strung out.

From becoming one with the water to the palpable camaraderie to that feeling of accomplishment as you run underneath the finish-line arch, open water swims are an exciting challenge and satisfying experience. Train smart (I can almost hear the Rocky theme song now…) and remember to have fun on event day!

We’ll see you and the rest of the Swim Across America family on the beach.
