About the Tour:

In the face of life’s most turbulent storms, the old nautical phrase “Hold Fast” was a directive to sailors to grip the rigging tight and weather the gale. For the 2027 Castaways Against Cancer, The Hold Fast Tour is our rallying cry. Cancer is a fierce and unpredictable sea, but we refuse to be swept away. This year, as we paddle, pedal, and run from Miami to Key West, we carry that steadfast resilience with us. We hold fast to hope. We hold fast to the memory of those we’ve lost, the resilience of survivors, and the relentless pursuit of a cure. No matter how rough the waters get, we grip tighter, move forward together, and stay anchored in our mission to light the way toward a cancer-free world.

About us:

The Castaways Against Cancer is a 100% volunteer non-profit comprised of fun-loving, mission-driven individuals focused on fighting cancer. What makes this team unique is the series of arduous journeys they endure every summer from Miami to Key West. Kayakers paddle 160 miles over seven days, runners relay 170 miles over two days, and cyclists pedal the same 170 miles in one grueling day, all to raise money, awareness, and honor those affected by cancer.

What began with a group of four sea-hippies on the water in 2000 has grown into a powerful movement with dozens of volunteers, raising millions for ground-breaking cancer research. The Castaways Against Cancer continues to be fueled by the original mission of its founder, Steve O'Brien, who more than two decades ago, got in his kayak after losing his mother to cancer. O'Brien was inspired to "light a candle rather than curse the darkness," which still fuels the Castaways and its community of supporters today. Patrick Linfors, a legendary Castaway and one of the original four kayakers, sums it up perfectly: “We’ve come so far in so many ways, but so much more needs to be done. We do this for a cure.”

In the end, it's simple. The Castaways kayak, cycle, and run, and your donations keep hope alive for a world that's one day, cancer-free.
