Castaways Against Cancer

Castaways Against Cancer Kayaking, cycling, and running from Miami to Key West to fund cancer research & honor those who have fought the fight. In the end, it's quite simple.

Over $2.5M raised since 2000 thanks to our supporters. 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 it endures 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 who have battled 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 that has raised more than $1.9 million in the fight against cancer. 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 cursing the darkness," which is what the Castaways and its community of supporters continue to do. The Castaways kayak, cycle, and run, donations help the world fight cancer, and we all pray for a cure.

Every summer, we journey from Miami to Key West with more than just our paddles. We carry the names and memories of those who have battled cancer — survivors, warriors, and those we’ve lost. We take those names with us along with us on our journey, reminding everyone that nobody fights cancer alone.

The 2026 Ring the Bell Tour has officially come to a close. 💙🔔

Yesterday, our Castaways arrived in Key West after an unforgettable journey, surrounded by family, friends, supporters, and survivors who welcomed them at our closing ceremony. Together, we celebrated every mile paddled, every step run, and every dollar raised in the fight against cancer.

A special thank you to Hyatt Centric Key West for hosting us year after year, and to Papas Pilar for helping us celebrate with an incredible after party.

For 27 years, this journey has been about more than reaching Key West—it’s about honoring those impacted by cancer and helping more patients one day ring the bell at the end of treatment.

More photos and memories to come. For now, we’re resting, reflecting, and soaking it all in. ☀️🌴💙
