Race facts
- Start line
- Gator Bowl Boulevard by EverBank Stadium (formerly TIAA Bank Field), downtown Jacksonville. Course crosses two St. Johns River bridges — the Main Street Bridge early and the steep Hart Bridge ("the Green Monster") near the end — finishing back by the stadium. Coordinate approximate (Nominatim, Gator Bowl Blvd).
- Traditional start (not confirmed for 2027)
- 8:00 AM (America/New_York) — Mass waves 8:00-8:15 AM (Wave 1 elites/qualified sub-1:30 at 8:00, walkers 8:15). In championship years the pro race uses an equalizer: elite women gun ~5 min ahead of elite men (endurancesportswire, 2025). Source: Gate River Run 2025 Race Roster [V].
- Field size
- 2025 finishers 13,856 [V] (Wikipedia), against 18,682 registered / "all events sold out" (Race Roster) [V] — registered > finishers. The nation's largest 15K. 2021 was artificially capped at 8,000 (COVID), so it is a low outlier.
- Registration
- open (1st Place Sports; sells out) + separate elite field by qualifying time / invitation
