What Is the F1 Grid Walk?
Team radio captures what drivers say once they're strapped in. The grid walk captures the chaotic ten minutes right before that — pundits, celebrities and team bosses all crammed onto a stretch of tarmac barely wider than two cars, with a camera crew trying to keep up. It's one of the few unscripted moments left in a heavily managed broadcast, and it has its own history, its own rules, and its own running joke about a driver who once refused to say a word.
F1 Grid Walk by the Numbers
- 1997: the year Martin Brundle did the first grid walk, at the British Grand Prix at Silverstone, for ITV.
- Rubens Barrichello: Brundle's first-ever grid walk interviewee — his own teammate from the previous season.
- 10 minutes: the official signal before the formation lap at which every journalist and non-technical guest must be off the grid.
- 16: the maximum number of team personnel permitted per competitor once the 3-minute signal is shown.
- 2021: the year of the "Brundle clause," barring bodyguards from accompanying celebrities on the grid.
How the Grid Walk Actually Works
The grid walk isn't a fixed studio segment — it's a live, roaming interview that starts once the grid has filled up with cars, mechanics, VIP guests and enough camera operators to make the whole thing look more crowded than the track itself. A pundit — historically Brundle, now shared across Sky Sports, Channel 4 and other regional rights holders — moves car to car, mic in hand, grabbing whoever will talk: a driver doing final seat checks, a team principal, or increasingly, a celebrity guest who showed up for the day.
It isn't scripted and it isn't guaranteed. Some years the biggest moment is a driver giving a genuinely useful strategy tease; other years it's a Hollywood actor who has no idea who's interviewing them. That unpredictability is the entire appeal — it's one of the last live, unedited windows into the grid before the broadcast switches to the tightly produced pre-lights-out package.
The Grid-Clearing Countdown
The grid walk doesn't end whenever the pundit runs out of things to say — it ends on a hard, official countdown that applies at every circuit on the calendar, regardless of how good the interview is going.
| Time before formation lap | What happens |
|---|---|
| ~60 minutes | Pit lane gates open; garage crews move equipment out onto the grid |
| 10-minute signal | All journalists, broadcasters and non-technical guests must leave the grid — this is what ends the grid walk |
| 3-minute signal | No more than 16 team personnel per competitor allowed to remain |
| 15 seconds | All remaining team personnel and equipment must be clear before the formation lap begins |
In practice, that means a grid walk almost always wraps up somewhere in the 30-to-40-minute-before-lights-out window, giving the pundit time to get back to the broadcast booth before the 10-minute mark forces everyone off anyway.
Who Started It — and the "Brundle Clause"
The grid walk wasn't Martin Brundle's idea. He's said plainly that ITV producers came to him with it: walk down the grid, describe what you see. His first attempt, at the 1997 British Grand Prix, saw him interview Rubens Barrichello — a former teammate, and about the only driver he was confident would actually stop and talk to him. Brundle carried the format through his later moves to the BBC and then Sky Sports, and by his own account the dynamic flipped over the years: early on, drivers who got skipped would complain to him directly; more recently, he says some drivers treat him "like a double glazing salesman."
The one real procedural change to the format in almost three decades traces back to a single incident. At the US Grand Prix, a member of rapper Megan Thee Stallion's security detail physically pushed Brundle away mid-interview and told him he couldn't approach her. Brundle went public about it afterward, and by his own account new rules followed shortly after: celebrities on the grid can no longer bring bodyguards. Brundle has jokingly taken credit for it ever since, dubbing it the "Brundle clause" — though he's also admitted he doesn't mind being ignored by a guest now and then.
Why Celebrities Cause the Most Friction
F1's post-Drive to Survive celebrity boom filled the grid with actors, musicians and athletes who have no F1 context — and grid walk interviews with them don't always land. Clips of a visibly confused celebrity, unable to name a single driver, have gone viral more than once, prompting recurring fan complaints that non-fans are taking up space and camera time that used to go to drivers and technical staff. The Brundle clause addressed the security side of that friction; the "who actually gets a mic" side remains an unscripted, case-by-case call every race weekend.
Frequently Asked Questions
What is the F1 grid walk?
The grid walk is a live pre-race broadcast segment where a TV pundit weaves through the grid interviewing drivers, team bosses and any celebrities in attendance, roughly 30-40 minutes before lights out. Martin Brundle made the format famous, but it's now shared across Sky Sports, Channel 4 and other rights holders.
When does the grid walk have to end?
At the official 10-minute signal before the formation lap, every journalist, broadcaster, and non-technical guest must clear the grid. That single countdown mark is what ends the grid walk every single race weekend, regardless of who's still mid-interview.
Who started the F1 grid walk?
Martin Brundle, working for ITV, did the first grid walk at the 1997 British Grand Prix at Silverstone. His first interviewee was Rubens Barrichello, his own teammate from the year before. The idea came from ITV producers, not from Brundle himself.
What is the "Brundle clause"?
It's Brundle's own nickname for a 2021-era rule barring celebrities' bodyguards from the grid, introduced after Megan Thee Stallion's security detail physically pushed Brundle away during a US Grand Prix grid walk and told him he couldn't approach her.
The Bottom Line
Three decades in, the grid walk is still the same basic idea Brundle's ITV producers pitched in 1997 — point a camera at whoever's willing to talk and let the ten-minute countdown decide when it ends. The one hard rule to come out of it (the "Brundle clause") deals with bodyguards, not with whether the interview is actually any good, which is why it still swings between genuinely revealing driver moments and a confused celebrity who's never watched a race.
