Roadbooks

Your roadbook, exactly as it is printed.

A roadbook holds stages. A stage holds sections. Keep a library of them, carry a multi-day event as a single roadbook, and key in the rows in the units and the time notation on the paper in front of you. Or key in one row, the distance and the target, and zero the partial at each sign or junction to call the distances off the paper. Holding the whole book does not oblige you to key in all of it.

The 3pRally roadbook strip on iPad, headed Brescia to Ferrara with its three stages and the first selected: a Regularity book of 11 rows over 40.45 km in 0:50.14, tabulated as section, type, rate, marks, partial, total and from start. PC 1 CAST 45.0 over 6.55 km; #2 TIME over 1.00 km; PC 2 CAST 45.0 over 3.35 km; #4 TIME over 4.00 km; PC 3 CAST 48.0 over 4.60 km; #6 TIME over 1.00 km; PC 4 CAST 48.0 over 2.60 km; #8 TRANSIT over 9.05 km; PC 5 CAST 42.0 over 4.80 km; #10 TIME over 2.00 km; and #11 TRANSIT over 1.50 km, finishing at 40.45 km and plus 0:50.14. The rate shows a dash on every TIME and TRANSIT row, which is the app's mark for a quantity that does not apply, and is reprinted on PC 2 and PC 4 even though the speed is unchanged, because the row type changed
  • 01

    A library, not a single roadbook

    Build, name and keep as many roadbooks as you run. Pick one at the start line and go.

  • 02

    Multi-stage events

    A four-day event is one roadbook with four stages, not four separate files to juggle.

  • 03

    The type decides what you enter

    Every row that covers ground starts with its distance, the column your odometer gets matched against. What else it asks for depends on what it is: a speed for CAST, a time for Time and Transit, nothing more for a special stage. 3pRally works out the rest and checks the row against the stage.

  • 04

    The format on the paper

    Miles or kilometres, two decimals or three, minutes-and-seconds or decimal minutes. Set it per roadbook and transcribe what you see. 3pRally stores it canonically underneath.

  • 05

    Build it anywhere. Drive with what fits.

    Everything here works on the iPhone alone. You never need a second device. But transcribing a roadbook is table work, and if you own an iPad it is an easier evening on the big screen. iCloud then puts it on the phone that actually fits your dashboard, because a lot of the cars worth rallying were not built with an iPad in mind. Export it and your co-driver has it too.

Four disciplines

One app, the whole rally.

Regularity is where 3pRally started. Now a roadbook can mix in the sector types real events actually use, so one app runs the whole rally, not just the parts of it that keep an average.

TSD · CAST · BBORR

Regularity

Hold a target average. 3pRally tracks your ideal time, your error against it, and the speed you need to recover, and tells you promptly, not at the end of the sector. Where the event posts a ceiling as well, the row carries an optional MAX: cross it and you are flagged so you know, not penalised.

Flat out

Special stage

A timed sector with no speed rules. The elapsed timer becomes the hero of the dashboard, splits run underneath it, and the fastest time wins.

Silver State · Targa

Open road

An optional base speed and an optional posted max, plus your class tech speed if you set one. 3pRally paces you inside all three at once, and holds you to whichever ceiling is lower.

Liaison

Transit

The parts nobody scores, written in so the totals come out right. A transit is due at the far end at a time and is not held to an average. A pause is a halt at a place, a regroup or a service point, which takes time off the schedule and no road at all.

While you drive

The co-driver that never loses its place.

Everything below is new in 5.0. It exists because of one problem: at speed, on a road you have never seen, you get about half a second to read the dashboard.

Upcoming section

Know what is coming before it arrives

As you approach the end of a section, a banner slides in to preview the next one: its type, its length, its sign face. Then it gets out of the way on its own. On the last section it previews the finish.

The 3pRally roadbook dashboard with the upcoming-section banner showing in the top corner: ideal speed 60, next sector type Time, 5.00 km away

Pace guidance

The speed you need, and the cap you cannot cross

A ceiling stands on screen for the whole part, not just as you reach it: a dark pill under the current speed, reading LIMIT where this stretch posts one. The pace tip tells you the speed to hold, clipped to the cap, so it never advises you into a penalty. Your class tech speed counts too: 3pRally holds you to whichever is lower, so an uncapped section is still policed, and the pill reads MAX when that ceiling is the one that binds. Go over and one thing turns red: the speed. The beep tightens the further over you are, and the run recap marks that leg MAX EXCEEDED.

The 3pRally open-road dashboard on iPhone in miles: the current speed 127.4 mph shown in red because it is over the cap, a black LIMIT 125 pill under it, average speed 30.1 mph, a red 02:57 late pill captioned VS BASE, a blue 95 base speed circle above the OPEN ROAD pill, and regressive distance 27.84 miles

Controls

Crossed early? Take it back.

Tap next too soon and 3pRally spots it, flags the part as cut short and gives you a few seconds to undo. The section reopens and the numbers go with it. Leave it cut short and it is recorded that way, rather than quietly pretending the figures are clean.

Voice & hands-free

Hands on the wheel, eyes on the road

3pRally speaks your speed, your average, your partial distance and your pace tips, and announces the section coming up, in the voice you choose. Pair a Flic button and run the whole stage without touching the screen.

External GPS

Works with the Bluetooth receivers that pair natively with iOS: Garmin GLO 2, Dual XGPS150A and the like.

Calibration

Calibrate against the calibration section. Or, following a roadbook, let 3pRally learn the correction from the controls you mark as you drive. Either way it stays visible.

Leaving on your minute

Tap go and start now, on a 30- or 60-second countdown, or at a clock time you set, so you can key in your minute at the control and park the phone. Set an official time offset and it counts to the organiser’s clock, not your phone’s. The last five or ten seconds can be called out loud, so nobody is watching a screen when the marshal drops their hand.

Counting down, not up

In Roadbook mode the distance and the time run down to the next control instead of up from the last one, which is how a crew reads the road. The app calls it regressive. Distance does this in every discipline; time only where there is a schedule to follow, so a special stage or an open road always shows elapsed time. It is a setting: turn it off and they count up instead.

Reverse

Missed a turn? Hit reverse, drive back, and the distance unwinds with you.

Energy saving

A long day should not end because the phone died. Pure black on OLED, a screen that blacks out when you are parked, and GPS that eases off until you move again. One switch for all three, or pick them individually.

Your organiser’s words

Section, leg, stage. Every series calls them something different. Pick the wording your event uses and the app follows.

Six languages

English, Italian, German, Spanish, French and Dutch.

Your voice

Choose the voice that reads your speed and your pace tips back to you.

Night driving

Light, Dark, or Auto to follow the device. Change it mid-run and the whole dashboard re-tints in place, so a dark screen at night never costs you a restart.

When you stop

Every section, scored.

Tap “next” and a one-row card tells you how that section went, without covering the readouts you are still driving by. Stop, and 3pRally lays out the whole run, then shows you how you actually drove it against the roadbook you wrote.

Export the recap as CSV and the track as GPX or KML.

Four dashboards

Three of them need no roadbook at all.

The roadbook is there for the events that hand you one. It is not a toll gate. Most crews run Advanced, the default. Tap next at each control and get their distance, time and averages without typing a thing. Change dashboard mid-run if you want to, and nothing resets. Whichever you pick, the numbers are big and the thing that matters most is the biggest thing on the screen.

01

Classic

One metric at a time: time, speed or distance, swapped with a single tap. No roadbook. The one we started with, more than ten years ago.

3pRally Advanced dashboard on iPhone: total and partial average speed, partial distance and partial time

02

Advanced

Everything at a glance: current and average speed, partial distance and time, totals above. No roadbook required.

How the 45 minutes are counted. Only while the counters are actually running, added up across every run you make that day, and reset on the next calendar day. A panel shows what is left as you drive. It is enough to judge the app on and not enough for a rally, so settle your access before the event.

Questions

Before you download.

What is the difference between 3pRally and 3pMaster?

3pMaster measures and navigates: a precise trip meter, an inclinometer, maps and track sharing, for off-road and overlanding. 3pRally competes on time: it holds a target average with CAST, follows a roadbook section by section, and runs open-road timed sections. Plenty of drivers use both. See 3pMaster.

Does it work for my kind of regularity?

Yes, for all of them, because they are one model underneath. US and SCCA TSD road rallies, European and historic regolarità, Latin-American regularidad, and UK and Commonwealth road rallies are all the same thing: hold a prescribed average over a measured distance. Where the average changes mid-section, write a row for each change and 3pRally paces you through the lot. Where the event is scored finely, set the time notation to decimal minutes and read hundredths or thousandths, which is how those roadbooks are printed in the first place. If yours is scored some other way, or wants something 3pRally does not do yet, tell us what it needs. Small developer, real inbox.

Do I need an external GPS?

No. 3pRally uses the GPS in your iPhone or iPad, and for most events that is enough. If you want better accuracy under trees or in a metal-roofed car, it works with the Bluetooth receivers that pair natively with iOS. We test with the Garmin GLO 2 and the Dual XGPS150A. There is a diagnostics screen so you can see exactly what fix you have.

Can I drive without touching the screen?

Yes. 3pRally speaks your speed, average, partial distance and pace tips, and announces the section coming up. Pair a Flic Bluetooth button and you can start, stop and advance a section with your hands on the wheel.

Do I have to build a roadbook?

No. Three of the four dashboards never ask for one. Most crews run Advanced, which is the default: tap go, tap next at each control, and you get total and partial distance, time and averages with nothing typed in beforehand. Classic does the same with bigger numbers, and Stage times a run you start and stop yourself.

That matters when the paperwork lands the night before, or at the start line. A roadbook is worth transcribing when you have the evening and the event is scored on holding an average. It is what unlocks the ideal speed, the time error and the pace tip. When you do not have the time, you are not locked out of anything else.

Does my GPS distance error move my averages?

Not any more. New in 5.0, a completed section is recorded at the distance your roadbook gives rather than the one the app measured. Your roadbook’s distances are treated as the true ones, so the app’s own distance error does not move your averages. If the two visibly disagree while you drive, 3pRally says so on the result card and offers “use measured distance” instead. It is a setting, so you can turn it off when the route you drove genuinely differs from the one that was surveyed. To be clear about what it does and does not touch: it changes the distance a section is recorded at, and therefore its average speed. It does not change your time.

Is my odometer accurate enough for regularity?

Calibrate it. Run the event's calibration section, tell 3pRally the true distance, and it derives a percentage correction and applies it, visibly, so you always know what correction is in force. You can also adjust the counters mid-stage, once-off or permanently.

New in 5.0, it can also learn the correction from the event itself. Turn on learn calibration from controls and the app compares your roadbook's distances with the ones it measures across the controls you mark, and corrects itself. It needs a few kilometres of marked controls before it says anything, and it gets more accurate the further you drive. Until then your own calibration is used, and the correction in force is always shown on the dashboard.

What happens if I take a wrong turn?

Hit reverse and drive back. The distance unwinds as you go, so when you rejoin the route your odometer is where it should be. If you cut a section short, 3pRally records that it was cut short rather than pretending the numbers are clean.

Can I share a roadbook with my team?

Yes. Export it as a 3pRally roadbook file and send it however you like. It opens straight into the app. Your own roadbooks and tracks sync across your devices with iCloud.

What do I get out at the end?

A result card for every section as you drive, a run summary when you stop, and a comparison of how you actually drove against the roadbook you wrote. Export the recap as CSV and the track as GPX or KML.

What languages is 3pRally in?

English, Italian, German, Spanish, French and Dutch. And because every series names things differently, you can pick whether the app calls them sections, legs or stages. It will use your event’s wording, not ours.

I bought 3pRally years ago. Do I have to pay again?

No. If you bought the app before it moved to a subscription, your purchase still stands. Open the app and use Restore Purchases. If you need a hand, get in touch.
