If you were going to "time yourself" you do it from Bridge to Gantry. The bridge is about 1/4 of a mile after coming out of the carpark, the Gantry is in the video below and it at the start of the straight.

In the dry, you will indeed get a fair old lick going quite quickly Clive, but you would probably run out of space before running out of puff.

At the end of the video, you will just start to see the cones appearing on the left hand side that marshall you back in.
