Racing Line Lab · physics-simulation estimates

Laguna Seca,
re-solved live.

Monterey, California · 3.60 km · 2.24 mi · counterclockwise

Open Laguna Seca in the Racing Line Lab and the browser re-solves the speed profile on the computed racing line as you change bike class, mass, power and grip. Every figure below is a simulation estimate on OpenStreetMap-derived geometry — not a measured lap.

Fully interactive free in the Lab — presets, sliders, ghost laps and PNG export.
