How do you train on the TT circuit? Looking at the map, in Esher the route comes up the side of Sandown race course (More Lans, Esher Green) then turns left onto Lammas Lane (A244) towards Hersham.

You can't left onto Lammas Lane, it is a single lane one way street at the junction. Do you take the big loop around Esher High Street and come down church street to get onto Lammas Lane (through 3 set of traffic lights)?

How will the Olympians do it during their training? Will no-one get to try the actual circuit until race day or are we in for a rash of story about athletes (and their support vehicles) ignoring traffic laws?
