02Overview

What Nelson Ledges is like to drive.

The full circuit layout at Nelson Ledges is 1.81 miles with 8 corners worth setting up for and about 24 ft of elevation change. A generic track-day car in our model brakes hard 6 times a lap and is at full throttle for about 43% of the distance; the longest straight runs roughly 1673 ft.

1 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 Nelson Ledges 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 Nelson Ledges.

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

    ↰ LeftslowhairpinTRACK numbering

    A slow left-hand hairpin that turns about 150°, tightening to a radius of roughly 22 m (72 ft). The model car brakes for about 160 m (525 ft), from 118 to 46 mph. The computed line turns in from the right side, takes a late apex, about 30 m after the corner’s geometric apex, and lets the car run out to the right on exit.

    ↰ LeftmediumchicaneTRACK numbering

    A medium left-hand chicane that turns about 126°, tightening to a radius of roughly 29 m (95 ft). The model car barely brakes here, carrying about 50 mph: a lift or a confident throttle balance. The computed line turns in from the right side, takes an early apex, about 80 m before the geometric apex, and lets the car run out to the right on exit.

05Configurations

Every mapped loop at Nelson Ledges.

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.

FAQ

Nelson Ledges, answered.

How long is Nelson Ledges?

OpenStreetMap maps 2 closed loops at Nelson Ledges Road Course, from 1.07 mi to 1.81 mi (2.92 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.

How much elevation change is there at Nelson Ledges?

About 24 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 2%.

Which direction does Nelson Ledges run?

OpenStreetMap doesn’t record a direction for the main layout at Nelson Ledges. Venues sometimes run both ways. TRACK takes the direction from your first laps.

Can I time laps at Nelson Ledges with my phone?

Yes, with the TRACK iPhone app (beta). It recognises Nelson Ledges 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 Nelson Ledges?

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 Nelson Ledges?

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 Nelson Ledges?

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