Data notes (1)
- Length check failed — 4339 m computed vs 2970 m published (+46.1%, Wikidata Q2623403). No mapped loop matches the published length (it may describe a layout OSM does not map as a closed loop, or a historic layout).

02Overview
What Alastaro Circuit is like to drive.
The full circuit layout at Alastaro Circuit is 2.69 miles with 17 corners worth setting up for. A generic track-day car in our model brakes hard 14 times a lap and is at full throttle for about 40% of the distance; the longest straight runs roughly 1066 ft.
11 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 Alastaro Circuit 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 data for this track isn’t loaded yet.
04Corner by corner
The corners at Alastaro Circuit.
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 right-hander
↱ RightslowhairpinTRACK numbering
A slow right-hand hairpin that turns about 155°, tightening to a radius of roughly 27 m (89 ft). The model car brakes for about 160 m (525 ft), from 120 to 47 mph. The computed line turns in from the left side, takes an early apex, about 5 m before the geometric apex, and lets the car run out to the left on exit.

Every mapped loop at Alastaro Circuit.
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 Alastaro Circuit. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Alastaro Circuit 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 Alastaro Circuit, 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
Alastaro Circuit, answered.
How long is Alastaro Circuit?
OpenStreetMap maps 6 closed loops at Alastaro Circuit, from 0.93 mi to 2.70 mi (4.34 km). These are mapped centerline lengths; the venue’s published figures can differ slightly. The published length we cross-check against is 1.85 mi.
Which direction does Alastaro Circuit 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 Alastaro Circuit with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Alastaro Circuit 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 Alastaro Circuit?
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 Alastaro Circuit?
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 Alastaro Circuit?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Alastaro Circuit from OpenStreetMap, with straight-line distances. Book early for big event weekends.
