Dave Brailsford will be giving us his reaction throughout the Tour de France as Team Sky make their debut in the world's greatest bike race.

When we caught up with him on the day before the start he was raring get going after months of planning, and 24 hours later he was delighted to see Geraint Thomas and Edvald Boasson Hagen both claim top 10 places in the prologue:

2030CET, Saturday 3 July

It was a phenomenal ride by Geraint to take fifth today. When you see him splitting Lance Armstrong and Alberto Contador it underlines the quality that the lad has. We've known for a long time that he's a real class bike rider and he proved that today in quite difficult circumstances. He committed himself and was absolutely brilliant.

And likewise for Edvald, to get two guys in the top ten is a great start and I'm very, very happy.

As far as Bradley was concerned, he went out in the rain and we didn't want him to take any unnecessary risks.

All the forecasts suggested it was going to be wet later in the day but that then changed to the rain coming earlier and then drying out. Obviously it's a risk we took and on this occasion it didn't quite pay off but that's absolutely fine and we've got no issues with it whatsoever.

We looked at his splits and his straight-line speed was as good as anybody's but round the corners he went super-slow. It's not what you'd normally expect from Bradley Wiggins but he thought 'right, I'm going to get through this safe and sound and think of the next three weeks'. And we're happy with that because we decided to make sure we're still in the bike race - no crashes and no risks.

We obviously knew that he was going to go a little bit slower as a result but we took that decision. It's the start of a long race and losing 20, 30, or 40 seconds at this point isn't a major thing at all.

The bottom line is that all the guys felt in great shape today which was the important thing for us and now we look forward to tomorrow.

1845CET, Friday 2 July

I arrived in Rotterdam a couple of days ago and since then it's been a question of making sure the logistical side is exactly as it should be, in terms of the kit and the equipment, as well as really supporting the team and the guys to make sure everyone gets on the same page as quickly as possible.

It always takes a day or two to get into the rhythm of things but the aim is to get into the groove as soon as we can. The media surrounding this race is bigger than anything we've had so far; that's an extra thing to deal with and think carefully about.

We've had plenty of staff meetings to make sure everything is running smoothly - it's all about picking up on the forward planning and resolving any issues that arise.

Thursday saw the team presentation and we've had our press conference today but while all that is going on the performance guys have only had their eyes on tomorrow's prologue and the stages after that.

They've been looking at every single stage and first up is making sure everything is right for the time trial; analysing the likely weather conditions, working on the riders' hydration and so on. Doing all the little things that we normally do and which all add up.

Most of the guys will do a ride, or at least turbo, in the morning ahead of the prologue.

We've decided to put Bradley off early (1655CET) and the thinking behind that is there could be thunderstorms around and the potential for rain later on, while the air is also likely to be warmer - and faster - in the afternoon.

It's a bit of a gamble but having him finish earlier and getting back to the hotel, fed and resting for the next day as soon as possible, is also probably a good thing.

But whatever time they go out and whatever conditions they face the guys will get out there and give it everything they've got.

It's a significant moment for us - we've had great support from Sky and this is a real opportunity to inspire more people to cycle - but I'm not sentimental in any way and that won't be in my thinking at all tomorrow, my mind will be firmly focussed on the job in hand. And that's supporting the lads in their performance and making sure we're doing everything we can to help them. That's where all my energies will be concentrated.
