02Overview
What DuQuoin State Fairgrounds Racetrack is like to drive.
The full circuit layout at DuQuoin State Fairgrounds Racetrack is 1.04 miles with 2 corners worth setting up for and about 3 ft of elevation change. A generic track-day car in our model brakes hard 1 times a lap and is at full throttle for about 42% of the distance; the longest straight runs roughly 1001 ft.
0 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 DuQuoin State Fairgrounds Racetrack 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 DuQuoin State Fairgrounds Racetrack.
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.
- C1
Fast left-hander
↰ LeftfasthairpinTRACK numbering
A fast left-hand hairpin that turns about 180°, tightening to a radius of roughly 25 m (82 ft). The model car brakes for about 40 m (131 ft), from 87 to 81 mph. The computed line turns in from the right side, takes an apex close to the geometric apex, and lets the car run out to the right on exit.

Fast left-hander
↰ LeftfasthairpinTRACK numbering
A fast left-hand hairpin that turns about 180°, tightening to a radius of roughly 22 m (72 ft). The model car barely brakes here, carrying about 87 mph: a lift or a confident throttle balance. The computed line turns in from the right side, takes a late apex, about 280 m after the corner’s geometric apex, and lets the car run out to the right on exit.

05Time it with TRACK
Drive DuQuoin State Fairgrounds Racetrack. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises DuQuoin State Fairgrounds Racetrack 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 DuQuoin State Fairgrounds Racetrack, 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
DuQuoin State Fairgrounds Racetrack, answered.
How long is DuQuoin State Fairgrounds Racetrack?
The mapped centerline of DuQuoin State Fairgrounds Racetrack is 1.04 mi (1.68 km) in OpenStreetMap. Published lengths are measured differently, so small differences are normal.
How much elevation change is there at DuQuoin State Fairgrounds Racetrack?
About 3 ft (1 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 1%.
Which direction does DuQuoin State Fairgrounds Racetrack run?
OpenStreetMap doesn’t record a direction for the main layout at DuQuoin State Fairgrounds Racetrack. Venues sometimes run both ways. TRACK takes the direction from your first laps.
Can I time laps at DuQuoin State Fairgrounds Racetrack with my phone?
Yes, with the TRACK iPhone app (beta). It recognises DuQuoin State Fairgrounds Racetrack 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 DuQuoin State Fairgrounds Racetrack?
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 DuQuoin State Fairgrounds Racetrack?
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 DuQuoin State Fairgrounds Racetrack?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near DuQuoin State Fairgrounds Racetrack from OpenStreetMap, with straight-line distances. Book early for big event weekends.
