02Overview
What İzmit Körfez Circuit is like to drive.
The full circuit layout at İzmit Körfez Circuit is 1.26 miles with 19 corners worth setting up for. A generic track-day car in our model brakes hard 13 times a lap and is at full throttle for about 23% of the distance; the longest straight runs roughly 443 ft.
12 of the corners are slow (under 50 mph in the model), 2 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 İzmit Körfez Circuit 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 İzmit Körfez Circuit.
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.

↰ LeftmediumchicaneTRACK numbering
A medium left-hand chicane that turns about 151°, tightening to a radius of roughly 15 m (49 ft). The model car brakes for about 110 m (361 ft), from 112 to 56 mph. The computed line turns in from the right side, takes an early apex, about 70 m before the geometric apex, and lets the car run out to the right on exit.

Drive İzmit Körfez Circuit. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises İzmit Körfez Circuit 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 İzmit Körfez Circuit, 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
İzmit Körfez Circuit, answered.
How long is İzmit Körfez Circuit?
OpenStreetMap maps 3 closed loops at İzmit Körfez Circuit, from 1.13 mi to 1.26 mi (2.03 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.
Which direction does İzmit Körfez Circuit 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 İzmit Körfez Circuit with my phone?
Yes, with the TRACK iPhone app (beta). It recognises İzmit Körfez Circuit 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 İzmit Körfez Circuit?
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 İzmit Körfez Circuit?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar lists its events too. TRACK doesn’t list events itself.
Where can I stay near İzmit Körfez Circuit?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near İzmit Körfez Circuit from OpenStreetMap, with straight-line distances. Book early for big event weekends.
