The Race
After an amazing second year of races, we're thrilled to announce the following line-up for 2019!

Saturday, August 10th, 2019: The TRIDENT half marathon -  
Register below!

Saturday, Dec 28th, 2019: Sand Spur Ultra-  Registration opens Earth Day, Apr 22nd, 2019!

Jen and Mike are both ultra runners with a love of trails. They work hard to put together races that draw registrations from around the globe!

In keeping with the "give back" give of ultra-running, any and all proceeds of our events will go to Palm Beach County Environmental Resource Management (PBCERM), who oversees the conservation of our county's natural areas!

Learn more about PBCERM below! 
 This is no ordinary trail run, and that's not just hype to sell tickets. The course is primarily sugar sand with a few short sections of gravel road, hard-packed scrubby flatwood, and one very short sidewalk section to help you catch your breath.​​​

It's an absolutely beautiful run and, in our opinion, one of the toughest.

Meet The Team
  1. Mike Brown
    Mike Brown
    "PR or ER!"
    From Ohio, Mike "EZ Brown" is the mastermind of the Sand Spur Ultra. Since running his first 5k in 2014, he's quickly made the transition into Ultra Distance and completed multiple races ranging from 5k-50miles, recently winning a 5k trail run and winning his AG in a 50 miler! He's known for his speed and "not so ez" pace! His proudest running moment - creating the Sand Spur! Aside from running, he's a proud father and super-talented photographer!
  2. Jen Quellhorst
    Jen Quellhorst
    "Second Place is First Loser!"
    Hailing from the middle of nowhere Ohio, Jen has been running since middle school cross-country and completed her first ultra-marathon in 2014. Since then, things have spiraled out of control with multiple 50k, 50 miler, 100k, and three 100 mile finishes. She recently qualified for Boston and is the recipient of multiple embarrasing finish line photos - if you didn't puke at the finish, you didn't run hard enough! She loves Pepsi-Max, her 2 Aussies and husband, M&Ms, and hip-hop.
