Imagine trying to read detailed directions while sitting inside a rally car bouncing across rocks and sand at well over highway speeds. Now imagine that one misunderstood instruction could send the vehicle several kilometres in the wrong direction.
That is everyday life for a Dakar navigator.
Modern rally-raid navigation involves far more than telling the driver to turn left or right. Co-drivers continuously process roadbook diagrams, kilometre readings, CAP headings, terrain references, waypoints, danger warnings, and the position of competing vehicles.
They then convert all that information into short instructions the driver can understand instantly.
The challenge becomes greater as speed increases. Dakar co-driver Brett Cummings has described navigating a car at rally-raid speeds as completely different from navigating while competing on a motorcycle, especially because of the enormous number of tracks and terrain choices.
Understanding how Dakar navigators process instructions at extreme racing speeds therefore reveals one of the most mentally demanding jobs in motorsport.
1. Navigators Are Constantly Looking Ahead
A Dakar navigator cannot simply react to the roadbook note currently displayed.
By the time the vehicle reaches that point, the navigator should already be thinking about what comes next.
Imagine a roadbook showing a junction at kilometre 153.40, followed 700 metres later by an off-track section requiring a specific heading. The navigator needs to call the first junction while simultaneously remembering that another instruction is approaching almost immediately.
This creates a continuous cycle of reading, interpreting, communicating, and preparing.
At high speed, the available window becomes tiny. A vehicle travelling at 120 km/h covers roughly 33 metres every second. A 300-metre warning therefore disappears in around nine seconds.
That is why good navigators rarely sound surprised. They are working ahead of the car rather than simply describing what is happening outside.
2. Distance Creates the Timeline for Every Instruction
Distance is one of the main organising tools inside a Dakar cockpit.
The FIA roadbook format connects navigation notes with cumulative and partial distances, while every stage receives its own roadbook. Electronic roadbooks are also controlled through stage-specific unlocking procedures.
The navigator constantly compares those numbers with the vehicle’s trip information.
Suppose an important junction appears at kilometre 212.65. The navigator may begin preparing the driver several hundred metres earlier, then progressively shorten the warning as the vehicle approaches.
A small distnace discrepancy can make things complicated.
Wheelspin in sand, a previous detour, or a navigation correction may affect how neatly the trip reading corresponds with what the crew sees outside. The navigator must recognise that difference instead of waiting blindly for an exact number.
This is why experienced co-drivers combine digital information with physical observation.
Numbers provide structure, but terrain confirms whether the crew is actually where it thinks it is.
3. Instructions Have to Be Compressed Into Simple Language
A Dakar roadbook can contain a surprising amount of information.
The driver does not need to hear all of it.
Instead, the navigator converts complex information into a compact instruction containing only what matters at that moment. That might include the approaching distance, direction, CAP heading, and danger level.
The wording also needs to be predictable.
If the navigator describes the same type of junction differently every time, the driver has to spend additional mental energy interpreting the language. Elite crews gradually develop a shared vocabulary where each phrase triggers an almost automatic response.
That consistant communication is especially valuable when the car is moving quickly.
There is no time for a long explanation while approaching a hidden turn.
The navigator needs to identify the problem, simplify it, and communicate it before the driver reaches the decision point.
4. CAP Headings Become Critical When Tracks Disappear
Not every Dakar instruction involves a visible road.
Competitors frequently cross open desert where the correct route may involve leaving an established track entirely.
This is where CAP headings become crucial.
A navigator may tell the driver to leave the visible trail and maintain a particular compass heading toward a valley, dune field, or distant waypoint. The crew then compares that heading with terrain clues and the next roadbook note.
The difficulty is that dozens of tyre tracks may be visible.
Some belong to competitors following the correct route. Others may belong to people who became lost.
Henk Lategan experienced this challenge while opening a Dakar 2026 stage after rain had washed away many of the smaller tracks.
With no motorcycle marks to provide clues, he described the stage as one of the hardest he had ever opened and credited navigator Brett Cummings with getting the crew through it.
At racing speed, choosing which track to trust becomes a rapid judgement call.
5. Waypoints Add Another Layer of Mental Processing
The roadbook is only part of Dakar navigation.
Crews also have to validate official waypoints.
Dakar’s description of a typical stage explains that some waypoints provide very limited GPS guidance. A Control Way Point, for example, is designed to verify that competitors respected the roadbook without providing normal directional navigation through the GPS.
FIA regulations also require roadbooks to list waypoints without simply giving competitors unrestricted coordinates.
That means the navigator must first use roadbook information to reach the correct area.
Only then can the navigation equipment provide whatever guidance is permitted for that waypoint type.
Missing the point creates a new decision: continue and accept the sporting consequence, or turn around and search again.
Carlos Sainz showed how costly that situation can become during Dakar 2026 when he and several rivals struggled around a difficult waypoint and repeatedly turned while searching for the correct route.
6. Extreme Speed Changes How Early a Call Must Be Made
The same navigation instruction can require completely different timing depending on vehicle speed.
A turn 200 metres away is relatively comfortable when travelling slowly through technical dunes. On a fast desert track, those 200 metres disappear almost immediately.
Navigators therefore adjust the timing of their calls dynamically.
Fast sections require earlier warnings. Complicated junctions may receive multiple calls. A dangerous feature often needs even more preparation so the driver has enough space to brake safely.
But calling everything too early creates another problem.
The driver may confuse the upcoming junction with an earlier track.
Finding the correct seperation between warning and execution is part of the navigator’s skill.
Mattias Ekström highlighted the difficulty during Dakar 2026 when discussing full-speed driving without useful tracks ahead. He praised co-driver Emil Bergkvist and noted how difficult navigation becomes for co-drivers when the driver is pushing at maximum pace.
In other words, driver speed directly affects navigator workload.
7. Navigators Must Filter Irrelevant Visual Information
The desert can contain too much information rather than too little.
There may be tyre tracks in multiple directions, small trails, vegetation, rocks, dry riverbeds, dunes, utility lines, and distant mountains.
A navigator cannot give equal attention to everything.
The roadbook tells the crew which environmental features actually matter.
For example, a navigator may ignore several obvious tracks because the roadbook indicates that the correct route follows a barely visible canyon. Or the crew may use a distinctive terrain feature to confirm its position before the next instruction.
This filtering becomes harder when competitors are following another vehicle.
Tracks can be psychologically persuasive. If several vehicles went one way, following them feels logical.
But Dakar history is full of situations where several leading crews make the same navigaton error because one competitor makes a mistake and others follow.
Professional co-drivers therefore use existing tracks as clues, never as unquestionable instructions.
8. Driver and Navigator Operate as One Decision-Making System
Great navigation depends heavily on trust.
The driver needs to commit to instructions even when the physical terrain appears to suggest another direction.
The navigator, meanwhile, has to understand how much information the driver can process while controlling the vehicle.
Brett Cummings explained that adapting to Dakar car navigation required developing a new routine with Henk Lategan because everything happens differently at high speed compared with his previous motorcycle experience.
Over time, their mistakes became smaller as their communication improved. This partnership becomes especially valuable when something goes wrong.
If the navigator realises the crew missed an instruction, there is little value in arguing about it. The priority immediately becomes finding the quickest safe correction.
Experienced crews communicate the problem, establish the new heading, adjust their trip reference if needed, and resume racing.
Recovering calmly can save more time than trying to pretend a mistake never happened.
9. Mental Endurance Matters Over Hundreds of Kilometres
A navigator might perform thousands of small cognitive actions during a long Dakar stage.
Read the next note. Check distance. Look outside. Verify heading. Call the driver. Confirm the junction. Advance the roadbook. Prepare for the next waypoint.
Then repeat.
The difficulty is maintaining that precision after several hours of vibration, noise, heat, stress, and physical impacts.
A single lapse in concentration near the end of a stage can erase excellent work from the previous hundreds of kilometres.
Modern Dakar competitors therefore train navigation almost like a separate athletic discipline.
Current competitor profiles continue to emphasise how quickly decisions must be made in speed racing.
Dakar co-driver Jan Rosa, for example, has explained that the biggest change when moving into faster rally-raid competition is how rapidly events develop and how quickly decisions have to follow.
Mental endurance is not secondary to physical performance.
Inside the navigator’s seat, it is performance.
Dakar navigators operate in a world where complicated information has to become simple instructions almost instantly.
They monitor distances, interpret digital roadbook notes, check CAP headings, locate waypoints, read terrain, filter misleading tracks, warn about dangers, and communicate with the driver while the vehicle moves at extreme speed.
The faster the car travels, the less time exists for every decision.
That is why elite rally-raid navigation is much more than reading directions. It is continuous information processing under pressure.
When you watch a Dakar car flying across the desert, pay attention to the person sitting beside the driver.
Every smooth change of direction may represent several calculations and decisions completed seconds earlier. The navigator is not simply following the race – they are helping determine where the race goes next.
