Toxic Trail 37

About the Event

The Toxic Trail 37 returns to Canal Point, Florida on June 27th, bringing with it a unique blend of endurance challenge and environmental activism along the banks of South Florida’s St. Lucie River. This is no ordinary road race; runners will traverse nearly 40 miles from Port Mayaca through Stuart Beach, navigating both serene country roads and bustling urban streets as they follow the trail of toxic water flowing from Lake Okeechobee to the ocean. The route traces a poignant path marked by signs and banners advocating for sustainable solutions to protect local ecosystems.

The atmosphere on race day is charged with purposeful energy, reflecting the community’s deep commitment to addressing environmental issues that impact their way of life. June in South Florida means high temperatures and humidity, yet runners are greeted by an array of supporters along the route who share a common goal: to raise awareness about water quality concerns affecting Palm City, Stuart, and beyond. The race winds through picturesque landscapes that transition from quiet rural settings into more populated areas where participants must navigate busy highways with careful attention to traffic laws.
The Toxic Trail 37 has been an annual event for several years now, fostering a dedicated community of runners who participate year after year in solidarity with their cause. Solo and relay teams alike have grown accustomed to the race’s traditions, such as gathering on Stuart Beach at the finish line for group photos that symbolize unity and determination. Over the years, the race has attracted hundreds of participants and garnered significant media attention, helping to keep environmental issues front-and-center in local discussions.
The course begins along US Route 441 near Port Mayaca Locks where runners will face cooler temperatures as they start their journey against traffic on quieter roads. As miles accumulate, the heat index climbs significantly, reaching over 100 degrees Fahrenheit by mile 23 when entering Stuart’s urban heart. The last few miles offer a rewarding finish at Stuart Beach with Atlantic Ocean views and an inviting double bridge crossing that marks the end of this challenging journey.
Aid stations are strategically placed approximately every five to seven miles along the course, providing essential support for both relay teams and solo runners. However, participants should plan accordingly as conditions can vary greatly, especially in terms of heat and humidity levels typical for June in South Florida. Runners are encouraged to utilize a crew if possible but must be prepared to handle unexpected challenges independently.
For those interested in participating, registration is now open through the event’s official website at https://ultrasignup.com/register.aspx?did=134585 with fees ranging from $110 for solo runners to $500 for a six-person relay team. The race offers multiple options including 2-Person Relay and 4-Person Relay categories, each designed to engage different levels of commitment while still promoting the shared cause.
Bib pickup will take place at the start location on US Route 441 / US 98 (Cross Section) near Port Mayaca Locks. Participants must ensure they have signed into their accounts before clicking on any invitation links sent via email for relay team registration assistance. Age requirements are set to accommodate adult runners and walkers who can handle extreme conditions.
As the Toxic Trail 37 approaches, it stands as a testament not only to individual endurance but also to community resilience in facing environmental challenges head-on. On June 27th, Canal Point will once again witness this remarkable event that combines athletic prowess with ecological advocacy, making every step count towards a healthier future for South Florida’s waters and communities.
The Toxic Trail 37, set against the backdrop of vibrant Stuart Beach on June 27th in Florida, USA, invites all who wish to join forces with dedicated runners as they run not just through miles but toward meaningful change.
