Jupiter Ridge Sand Spur

Jupiter Ridge Sand Spur is a Christmas-themed trail running event held in Jupiter, Florida, organized by Sand Spur Ultra. The event marks its 10th edition and offers three looped distances that run inside Jupiter Ridge Natural Area, a protected 270-acre coastal scrub site.

Distances include:

  • 50K seven loops on an approximately 4.5 mile course
  • 30K Silent Night four loops on the same looped course
  • Half marathon three loops on the same looped course

The course uses trails through ancient coastal sand dunes and scrub habitat, passing features named in the course description such as the Trident dunes and a sand pine Tunnel of Love, with repeated views of the Intracoastal Waterway. The 50K accumulates about 1,400 feet of elevation gain; the half marathon accumulates about 600 feet. One dune on the property rises about 49 feet above sea level.

Field size is limited to 80 entrants to reduce environmental impact; the organizer works with Palm Beach County Environmental Resources Management on permitting and site protection. There are two aid stations on course, a drop bag zone at the start/finish, and access to personal gear each loop. It is possible to complete the course with a handheld water bottle; runners are never more than about 2.25 miles from aid. Awards include a finisher medal and specialty awards for top finishers. Entry fees are listed between 111.25 and 139.60 USD. Refund and credit policies apply with deadlines noted for full refunds, partial refunds, and race credit options.
