The Jupiter Ridge Sand Spur returns to Jupiter, Florida on December 26th, offering runners a unique Christmas-themed experience with three challenging distances through the ancient sand dunes of Jupiter Ridge Natural Area. Runners will gather at various times throughout the day for their respective races. The full 50K race begins promptly at 7:00 AM and offers participants seven loops on the scenic but demanding course, which is known for its elevation changes and iconic features such as the Trident dunes and sand pine Tunnel of Love. For those who prefer a shorter distance, there's also a half marathon starting two hours later with three loops. The Silent Night 30K race commences at 6:00 PM in cooler evening temperatures, providing runners with an additional four loops through the same stunning terrain. Jupiter Ridge Natural Area is characterized by its firm and slightly soft trail conditions due to the sandy landscape, making it a unique setting for endurance races. The area's history dates back millions of years when ancient dunes formed during ice ages, creating one of Florida’s rarest living communities known as Florida Scrub. This habitat supports over 200 species of plants and animals, some found nowhere else in the state. Runners can choose from three distances: a grueling full 50K race, a half marathon that is equally challenging but shorter, or the Silent Night 30K night race. Each offers its own unique experience through this historic natural area.
