After 514.5km of racing over three days, there are still 71 men only one second shy of the yellow jersey in the 100th Tour de France. The race leader himself, Jan Bakelants, knows his colleagues are strong and that they should stand a chance of a good performance in the team time trial around Nice but to keep the yellow jersey the essentially have to win. He doesn't expect that they will.
There are several squads that specialise in this discipline: the dominate formation of last year's Tour – Sky, the winners of the TTT in 2011 – Garmin-Sharp; runners-up in the equivalent stage of 2011 – BMC Racing; reigning world TTT champions – Omega Pharma-Quickstep... or perhaps even Astana, Saxo-Tinkoff or Movistar.
If we make the list of potential winners any longer, we'll mention every squad in the race but this is a day when tactics are crucial. The time is taken on the fifth rider across the line and the winning team is likely to take the yellow jersey. This final fact raises an important question: does the real title favourites for the 100th Tour want to lead quite so early? Tune in and find out the answer to this quandary and a few others. This is a day to expose the weakness – or strengths – of the GC specialists.
