Per-Leg Mode
Focus deeply on individual leg execution with auto-rotation and synchronized data.
The Per-Leg Mode (internally known as the Leg Navigator) is the core analysis tool for deeply investigating specific route choices. By slicing the GPS track using the control locations, Routster isolates your performance between two specific points.
How It Works
Viewing Modes and Controls
Auto-Rotation
By default, the Per-Leg view uses Leg Rotation. Routster calculates the bearing between the starting control and the destination control of the current leg, then applies a CSS rotation matrix to the map wrapper.
This ensures the destination control is always perfectly "up" relative to your screen, matching how a runner naturally thumbs and orientates their map in the forest. You can toggle this back to "North Up" in your Global Settings.
Merged Legs & Gaffling (Span Range)
In relay events or gaffled courses, WinSplits might combine multiple physical course controls into a single "split".
To handle this, the Per-Leg engine supports a spanRange. It can dynamically merge multiple consecutive course legs (e.g., Controls 4, 5, and 6) into a single virtual leg so that the visual map matches the aggregated WinSplits data chip for that section.
Other Runners' Tracks
If you have uploaded or linked other competitors' GPS data, you can toggle their tracks on the current leg. To prevent clutter, other runners' tracks are rendered beneath your own primary track, but are fully interactive. Tapping a track reveals a tooltip with the runner's name and leg split time.
Focus Highlights
When you click on a specific mistake in the AI Coach panel (like a 30-second stop), the Per-Leg map will automatically jump to the correct leg and trigger a pulsing visual ring at the exact `x/y` pixel coordinate of the mistake.
