The Experience
On January 23–24, 2027, the Gemini Springs 2-Day Challenge brings five distances — 5K, 10K, half marathon, marathon and 50K — to a Central Florida park of palm hammock, live oak and cypress. It is a brand-new event on the calendar, and the setting is unmistakably Floridian: a tunnel of trees, humid January mornings that hover between roughly 50 and 68 degrees, and very little rain to worry about.
The half runs out-and-back on the Spring-to-Spring Trail, also known as the Pat Northey Pathway — an accessible, measured path where every turnaround sends you back past the O.K. Corral for aid and the start of the next out-and-back. It gets familiar quickly, and that is the point. The race is cupless, so carry a handheld, vest or waist pack; the half goes off at 7:10 a.m., ten minutes after the marathon and 50K, with a single 4 p.m. cutoff for the whole day rather than per distance.
Because the core distances run both days, the weekend takes on the feel of a small encampment: ten primitive tent sites inside the park, each with a fire ring and picnic table, and the same faces lining up again the next morning. Come for the double, or simply for the half and the tree tunnel.
Race-provided description
THE COURSE The Gemini Springs 2-Day Challenge runs on the Spring-to-Spring Trail / Pat Northey Pathway in DeBary, FL, on January 23–24, 2027. An out-and-back on an accessible, measured trail. Palm hammock, live oak, and cypress. Every repeat brings you back to the O.K. Corral for aid and to begin another out-and-back. It gets familiar real quick. That is the point. DISTANCES AND START TIMES 7:00 AM — 50K and Marathon 7:10 AM — Half Marathon 8:00 AM — 10K and 5K Available distances: 50K · Marathon · Half Marathon · 10K · 5K WHAT YOU GET. WHAT YOU DON'T. No shirts. No race bags. No expo. No chip timing. Nothing in a bag at the finish. A measured course. A clock. A finish that gets recorded. And a reason to come back tomorrow. Every finisher earns the Daily Finisher Medallion. Run both days on a Streak and you earn the Tier Patch. RACE DAY CUTOFF 4:00 PM. This applies to the full race day — not per distance. Runners still on course after the cutoff will be directed off course. PARKING To reach the O.K. Corral parking lot, turn left into the main entrance of Gemini Springs Park from Dirksen Drive. Follow the main park road, and when the road splits, stay to the left. This lane guides you directly into the West Parking Lot, which sits adjacent to the dog park and the O.K. Corral pavilion. CAMPING Primitive tent camping only — ten sites inside Gemini Springs Park, each with a fire ring, picnic table, and groomed tent pad. No RVs. Reserved directly through Volusia County (386-736-5953), not through race registration, and sites are limited. AID STATION This is a cupless event. Carry your own fluids — handheld bottle, vest, or waist pack. MileBuilt provides water, an electrolyte drink, and basic snacks at the O.K. Corral. Do not rely on the aid station as your complete nutrition plan, especially for longer distances or multi-day participation. BIB PICKUP Available on race day beginning one hour before your scheduled start time — honor system, no ID required. A friend may pick up on your behalf. No bib transfers. FINISH Not chip timed. When you finish: cross the line, strike the GONG, then complete the Clock Out at the MileBuilt Time Clock. Official finish times are recorded at the MileBuilt Time Clock and verified by the Race Director before results are posted. Every runner must complete the Clock Out process to receive an official finish record. One day is a full race. Two days is a Streak.
