02Overview
What Inje Speedium is like to drive.
The full circuit layout at Inje Speedium is 2.47 miles with 20 corners worth setting up for. A generic track-day car in our model brakes hard 19 times a lap and is at full throttle for about 34% of the distance; the longest straight runs roughly 1099 ft.
7 of the corners are slow (under 50 mph in the model), 0 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Inje Speedium later.

The speed trace is a model, not a real lap: a generic track-day car (about 1.1 g of cornering grip, 1 g braking, 150 W/kg) driven on the computed line through an assumed 12 m wide track. Use it to see where the braking zones and flat-out sections are, not to predict your speeds. Elevation data for this track isn’t loaded yet.
04Corner by corner
The corners at Inje Speedium.
TRACK’s own corner numbering (C1, C2…), found from the curvature of the mapped centerline. It isn’t the official turn numbering. Each diagram shows the computed line: the minimum-curvature path through an assumed 12 m wide track. It’s a geometric starting point. Your instructor’s line comes first.

↱ RightmediumcornerTRACK numbering
A medium right-hand corner that turns about 42°, tightening to a radius of roughly 41 m (135 ft). The model car brakes for about 80 m (262 ft), from 88 to 58 mph. The computed line turns in from the left side, takes a late apex, about 110 m after the corner’s geometric apex, and lets the car run out to the left on exit.

Every mapped loop at Inje Speedium.
TRACK finds each closed loop in the OpenStreetMap raceway network. Named layouts come from OSM circuit relations; the rest are named by length, and some may be combinations the venue never runs. Your first session confirms which one you drove.

06Time it with TRACK
Drive Inje Speedium. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Inje Speedium and the layout from your GPS trace, then times every lap and sector with a live delta to your best.
- 1DetectTRACK matches your first few hundred metres against every mapped layout at Inje Speedium, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is estimated. When you’re stopped, TRACK shows it on the map: accept it or tap to move it. You’re never asked while driving.
- 3Laps, timed retroactivelyLaps you drove before confirming are timed from the recorded trace, so you don’t lose your first session.
- 4Go furtherSync a GoPro for video with telemetry and let TRACK Engineer point out where the time is. External 10–25 Hz GPS receivers for tighter sectors are awaiting hardware validation.
- Venue and layout detection is tested on simulated drives over real OpenStreetMap circuits, not yet in a real car. Compatible GPS receivers

FAQ
Inje Speedium, answered.
How long is Inje Speedium?
OpenStreetMap maps 6 closed loops at Inje Speedium, from 0.84 mi to 2.47 mi (3.97 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.
Which direction does Inje Speedium run?
The main mapped layout runs clockwise, from one-way tagging in OpenStreetMap. Check the event’s driver briefing: some venues run reverse-direction days.
Can I time laps at Inje Speedium with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Inje Speedium and the layout you’re driving from GPS, then times laps and sectors. A phone’s GPS is good for lap times; an external 10–25 Hz receiver tightens sector splits.
Where is the start/finish line at Inje Speedium?
TRACK estimates the line from the mapped geometry (usually beside the pit lane, or on the longest straight). It isn’t verified on site, so the app asks you to confirm or move it before timing your first session here.
How do I find track days at Inje Speedium?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar (also linked) lists its events too. TRACK doesn’t list events itself.
Where can I stay near Inje Speedium?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Inje Speedium from OpenStreetMap, with straight-line distances. Book early for big event weekends.

TRACK shows no lap records or official results for this venue. Driving advice is general: your instructor, the event’s rules and the venue’s rules come first.
