02Overview

What M1 Concourse is like to drive.

The full circuit layout at M1 Concourse is 1.42 miles with 9 corners worth setting up for and about 22 ft of elevation change. A generic track-day car in our model brakes hard 7 times a lap and is at full throttle for about 37% of the distance; the longest straight runs roughly 705 ft.

7 of the corners are slow (under 50 mph in the model), 1 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 M1 Concourse later.

Model speed (generic track-day car)Elevation · USGS 3DEP

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 M1 Concourse.

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.

    Medium right-hander

    ↱ RightmediumhairpinTRACK numbering

    A medium right-hand hairpin that turns about 147°, tightening to a radius of roughly 37 m (121 ft). The model car barely brakes here, carrying about 55 mph: a lift or a confident throttle balance. The computed line turns in from the left side, takes a late apex, about 30 m after the corner’s geometric apex, and lets the car run out to the left on exit.

    Fast right-hander

    ↱ RightfastessesTRACK numbering

    A fast right-hand esses that turns about 30°, tightening to a radius of roughly 45 m (148 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 barely brakes here, carrying about 80 mph: a lift or a confident throttle balance. The computed line turns in from the left side, takes a late apex, about 90 m after the corner’s geometric apex, and lets the car run out to the left on exit.

FAQ

M1 Concourse, answered.

How long is M1 Concourse?

The mapped centerline of M1 Concourse is 1.42 mi (2.29 km) in OpenStreetMap. Published lengths are measured differently, so small differences are normal.

How much elevation change is there at M1 Concourse?

About 22 ft (7 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 4%.

Which direction does M1 Concourse 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 M1 Concourse with my phone?

Yes, with the TRACK iPhone app (beta). It recognises M1 Concourse 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 M1 Concourse?

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 M1 Concourse?

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 M1 Concourse?

This page lists hotels, campgrounds, restaurants, fuel and parts stores near M1 Concourse from OpenStreetMap, with straight-line distances. Book early for big event weekends.
