Bizarrely whilst we are right in the thick of it (lost count of the number of times I've left Wout unable to keep up with me this week - my tenuous claim to fame), it's hard to keep track of what is really happening. I know when there is a break and what the gap is, but even once you've worked through the peloton and are now ready to be overtaking them, you don't really clock who it is. You're looking in mirrors to see what's happening behind, looking at the position of the racers and the camera bike to avoid getting into shot, looking how the road changes ahead for if it is safe and what your optimum line will be too avoid affecting them and/or hitting road furniture, watching for the team cars moving around, checking if the regulator has any specific instructions for the overtake (which side), or if he wants you to hang back, if they are riders coming up from behind to join the break (in which case they get priority on road space), if there are any other bikes trying to get through etc. The last thing you do is check the race numbers...
I generally don't know what actually happened until I see it on TV!
