02Overview

What The Ridge is like to drive.

The full circuit layout at The Ridge is 2.45 miles with 16 corners worth setting up for and about 253 ft of elevation change. A generic track-day car in our model brakes hard 14 times a lap and is at full throttle for about 36% of the distance; the longest straight runs roughly 787 ft.

8 of the corners are slow (under 50 mph in the model), 3 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 The Ridge 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 The Ridge.

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.

    Slow left-hander

    ↰ LeftslowchicaneTRACK numbering

    A slow left-hand chicane that turns about 160°, tightening to a radius of roughly 8 m (26 ft). The model car brakes for about 25 m (82 ft), from 48 to 37 mph. The computed line turns in from the right side, takes a late apex, about 90 m after the corner’s geometric apex, and lets the car run out to the right on exit.

Drive The Ridge. TRACK knows where you are.

No setup and no transponder. Start a session in the paddock and TRACK recognises The Ridge and the layout from your GPS trace, then times every lap and sector with a live delta to your best.

FAQ

The Ridge, answered.

How long is The Ridge?

The mapped centerline of Ridge Motorsports Park is 2.46 mi (3.95 km) in OpenStreetMap, against a published 2.47 mi. Published lengths are measured differently, so small differences are normal.

How much elevation change is there at The Ridge?

About 253 ft (77 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 56%.

Which direction does The Ridge 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 The Ridge with my phone?

Yes, with the TRACK iPhone app (beta). It recognises The Ridge 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 The Ridge?

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 The Ridge?

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 The Ridge?

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