Spring-To-Spring
Trail

The Gemini Springs 2-Day Challenge runs on the Spring-to-Spring Trail / Pat Northey Pathway in DeBary, FL. The course starts and finishes at the O.K. Corral pavilion at Gemini Springs Park.

Every distance follows the same out-and-back route — out along the trail to a marked turnaround and back. Every repeat brings you back to the O.K. Corral for aid, then sends you out again.

Oak and palm hammock overhead nearly the whole way.

Runners may access their own vehicle if parked near the course, though reaching it means stepping off the path and will add distance.

It gets familiar real quick. That is the point.
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.

Know
The Morning.

Parking

Gemini Springs Park, 37 Dirksen Drive, DeBary, FL 32713. Turn left into the main park entrance from Dirksen Drive, follow the main park road, and stay left where the road splits. That lane leads directly into the West Parking Lot, adjacent to the dog park and the O.K. Corral pavilion. Arrive early.

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 aid station. Do not rely on the aid station as your complete nutrition plan, especially for longer distances or multi-day participation.

Bib Pickup

Bibs are available for pickup on race day beginning one hour before your scheduled start time — honor system, no ID required. A friend may pick up your bib on your behalf. No bib transfers — your bib is registered to you.

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.

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.

One Day Is A Full Race.
Two Days Is A Streak.

Every finish earns the Daily Finisher Medallion. Run every day on a Streak and you earn the Tier Patch.

Open Path

Standalone

One race day. Pick any distance. No pledge. No tier. Daily Finisher Medallion.
