02Overview
What COTA is like to drive.
The full circuit layout at COTA is 3.42 miles with 18 corners worth setting up for and about 95 ft of elevation change. A generic track-day car in our model brakes hard 15 times a lap and is at full throttle for about 45% of the distance; the longest straight runs roughly 2986 ft.
6 of the corners are slow (under 50 mph in the model), 4 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. Some apexes sit on crests, where the car goes light. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for COTA 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: USGS 3DEP 1/3 arc-second (NED 10 m) via OpenTopoData, sampled every 25 m along the mapped centerline.
04Corner by corner
The corners at COTA.
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.

Turn 1
↰ LeftslowhairpinTRACK numbering
A slow left-hand hairpin that turns about 144°, tightening to a radius of roughly 13 m (43 ft). It climbs through the corner (about 2% grade) and goes over a crest, so the car goes light at the apex. The model car brakes for about 170 m (558 ft), from 126 to 33 mph. The computed line turns in from the right side, takes an early apex, about 10 m before the geometric apex, and lets the car run out to the right on exit.

↱ RightfastcornerTRACK numbering
A fast right-hand corner that turns about 77°, tightening to a radius of roughly 78 m (256 ft). It drops through the corner (about 3% grade). The model car barely brakes here, carrying about 74 mph: a lift or a confident throttle balance. The computed line turns in from the left side, takes an early apex, about 65 m before the geometric apex, and lets the car run out to the left on exit.

Every mapped loop at COTA.
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 COTA. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises COTA 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 COTA, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is mapped · unverified. 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
COTA, answered.
How long is COTA?
OpenStreetMap maps 2 closed loops at Circuit of the Americas, from 2.48 mi to 3.42 mi (5.50 km). These are mapped centerline lengths; the venue’s published figures can differ slightly. The published length we cross-check against is 3.43 mi.
How much elevation change is there at COTA?
About 95 ft (29 m) between the lowest and highest points of the full circuit layout, from USGS 3DEP elevation data sampled every 25 m. The steepest stretch is around 12%.
Which direction does COTA run?
The main mapped layout runs counter-clockwise, from one-way tagging in OpenStreetMap. Check the event’s driver briefing: some venues run reverse-direction days.
Can I time laps at COTA with my phone?
Yes, with the TRACK iPhone app (beta). It recognises COTA 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 COTA?
The line TRACK uses comes from a start/finish point placed in OpenStreetMap. 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 COTA?
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 COTA?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near COTA from OpenStreetMap, with straight-line distances. Book early for big event weekends.
