Thank you for your support!! Boston frogman swim!! Sarah’s former Navy swimming teammate Sylvia, now a Navy Reserve officer, will be in the water as well. Her paddler, Matt, is a former Navy SEAL.
Together, the swimmers and paddlers are part of a larger team supporting the Boston Frogman 5K and the Navy SEAL Foundation.

For Sarah, that name is Chief Petty Officer (SEAL) Zackary “Zack” Miller II.
Zack was a close friend and a member of the Naval Special Warfare community.
He had endured seven deployments. He had received a Purple Heart. He had spent a career operating in places most Americans will never see.
Then came glioblastoma.
In 2021, Zack was diagnosed with the aggressive form of brain cancer.
Roughly six weeks later, he was gone.
That timeline is difficult to reconcile.
A man who had been trained to survive some of the world’s most dangerous environments was taken by cancer in a matter of weeks.
Sarah will carry Zack’s name through Boston Harbor not only in remembrance, but also in hopes that his story can help draw attention to glioblastoma and to the families left navigating life after devastating illness and loss.

The Boston Frogman 5K raises money for the Navy SEAL Foundation and the Naval Special Warfare community it serves.
And that community extends well beyond the person wearing the uniform.

The Navy SEAL Foundation exists to support Naval Special Warfare warriors, veterans and their families through the different seasons and challenges associated with that life.

And somewhere between the starting line and the finish, Sarah will be carrying the name of a friend who isn’t there to swim beside them.
Zack Miller.
That’s ultimately what this swim is about.
Remembering those who gave so much.
Standing beside those who continue to serve.
And supporting the families who have quietly carried the weight alongside them.
Give to those who continue to give.
Support the warriors, veterans and families of the Naval Special Warfare community through the Navy SEAL Foundation, and help ensure that the families who quietly stand behind some of our nation’s most demanding service are supported when they need it most.

Today marks five years since we lost Zack Miller: a son, teammate, warrior, and larger-than-life friend whose impact continues to ripple across the world every single day.

If you knew Zack, you knew the energy he carried into every room. The jokes, the stories, the loyalty, the Southern charm, and the way he made people feel seen and welcomed no matter who they were. He lived fully, loved deeply, and served this country with extraordinary courage through seven deployments as a Navy SEAL, including multiple combat tours in Afghanistan. Even in his final fight against glioblastoma, Zack faced life the same way he always did, with strength, humor, and heart.

Five years later, his legacy is stronger than ever.

What began as heartbreak has grown into a global community determined to honor Zack by fighting the disease that took him from us far too soon. Through the work of the Zack Miller Legacy Foundation, we continue funding glioblastoma research, supporting awareness initiatives, and bringing people together through purpose, friendship, and action.

Over the next few days, friends across the country, and around the world, will complete the “ILL MILL” workout in Zack’s honor:

5 Rounds for Time

• 500m Row
• 20 Kettlebell Swings @ 70 lbs
• 20 Push-Ups
• 20 Wall Balls @ 20 lbs
• 20 Pull-Ups

Cool down with some curls just because

And Zack’s legacy continues far beyond one workout. This year alone, supporters are participating in events like the Frogman Swim in Boston this September (thank you ), the UK Field Day in London later this month, and the Annual Chili Cook-Off in Zack’s hometown: all carrying Zack’s spirit forward and helping us continue the fight against glioblastoma.

To everyone who has supported this mission over the last five years: thank you. Every donation, workout, event, prayer, and conversation matters more than you know.

Today, we remember Zack the best way possible: by celebrating the incredible life he lived, living our own lives to the fullest, and continuing the mission he inspired.

ILL MILL is with us forever ❤️
