Naturally it was tempting fate to comment on how smoothly things had been going. As we descended the climb from Tignes a light on the dashboard came on. It was a circle with black lines flanking either side. "What do you reckon that means?" asked Simon, who was driving.
I wasn't sure but one thing I did know was that lights on dashboards rarely mean "Hey, it's me, I'm fine, just saying hello!"
I rang Luc, our Belgian photographer and owner of the Broomwagon.
"The manual is under the seat. It probably means there's a problem with the brakes. Don't worry too much, give me a call back if it doesn't go out," he said.
Driving down steep Alpine road in several tonnes of metal knowing that the brakes may or may not be on the blink was a little troubling, despite Luc's relaxed assessment.
The light came on and then went out all day as we drove a long, long way, from Tignes to Aix-en-Provence. The Tour's ninth stage was heading to Briancon, a town consisting of very narrow streets and tucked away in a very awkward part of the Alps. Had we gone there we may well have not managed to get out until Friday. We also had to get Tom Simpson, our photographer, to Marseille airport.
It was hot, so very hot, almost 40 degrees and neither Simon nor I were in the mood for long stints of autoroute driving. We kept stints behind the wheel to a manageable hour-and-a-quarter. We stopped at a service station for lunch.
Now, ten years ago, French service stations were far, far superior to British ones. In the past decade the unthinkable has happened and Britain, with its Welcome Breaks and Costa Coffees is now preferable to the fly-ridden cesspits on French motorways.
Even a good service station is still a depressing place, designed to erode away your soul from the inside so you don't notice how awful the food is. Everyone is there by necessity rather than choice.
Our meals were stunningly inedible. Tom's Toulouse sausage looked like it had walked up from Toulouse by itself. Simon and I opted for the penne bolognaise and my initial indignation that the serving slave had been so tight with the portion of sauce turned to relief when I actually tasted it.
Bellies full but spirits plunging we ploughed on, scorching kilometre after scorching kilometre. Kamikaze lorry drivers from the Czech Republic, Poland and Italy doing their best to wipe us off the road.
We arrived at our campsite on the outskirts of Aix-en-Provence in time to watch the stage finish in what was effectively a laundry room with a television in it. Oh the glamour. The Tour de France felt about a million miles away, although we were sure that our strategy of getting ahead of the race by half a day would pay off.
In the late afternoon, I headed to the town centre to meet Ed, who had flown in to Marseille and caught a bus, a step up in his choice of transport after he apparently hitch-hiked from Chateau-Chinon to Nevers last week at the end of his first tour of duty.
Simon went on a wild goose chase to do some laundry and buy some swimming trunks while Ed and I had a beer in Aix and marvelled at the fact that the two waiters at the Hotel des Deux Garcons looked just like Miguel Indurain - with his post-retirement longer hair - and Carlos Sastre.
Simon finally arrived in the town centre at 9.30, having failed to find any swimming trunks except in a designer boutique where they were asking 100 euros for them.
Eventually, at around 10pm, we ate. It seems that, whichever way you cut it, no matter what time the working day finishes, the law states that anyone covering the Tour in a camper van cannot eat before ten.
Our taxi driver told us the forecast for the next week is 35 degrees every day. Our stamina and patience is about to be tested to the full.
Where we stayed: Camping Chantecler in Aix-en-Provence
What we ate: Provencale lamb in La Bastide du Cours in Aix-en-Provence
Kilometres driven: 445 kilometres (total so far: 1,799km)
