Open Donington Park (Grand Prix Circuit) 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.
The map and these reference laps are free in the Lab; live solving on this track unlocks with the $29 lifetime all-tracks pass.
