Harris Hill Raceway (Counter-clockwise),
re-solved live.
San Marcos, Texas · 2.93 km · 1.82 mi · counterclockwise
Open Harris Hill Raceway (Counter-clockwise) 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.
