Everything a race director needs

From first GPX import to signed permit PDF — RaceFlows handles the full pre-event workflow.

🔥

Density heatmap

See crowd density per segment in real time. Scrub the timeline or play back the race to watch congestion build and clear.

⚠️

Bottleneck detection

The engine automatically flags segments where density exceeds your threshold — no manual inspection needed.

📋

Permit map authoring

Place aid stations, road closures, medical posts, and checkpoints on the map. Export a permit-ready PDF in one click.

⏱️

Road closure timing

Derive recommended open/close windows for every closure directly from the simulation, with configurable safety buffers.

🗺️

Simulate the full field

Model thousands of runners across one or multiple courses. Set field size, pace bands, and start protocols per course.

👥

Staffing plan

Generate a volunteer count and role breakdown per feature using configurable rules — marshals per intersection, volunteers per aid station.
