Hi, I plan to be there at about 08.30/09.00 for signing on, but no need to be there that early for spectating. The action starts about 09.30 and goes through the day, I plan to do a few runs depending on weather. Its difficult to know how busy it will be but parking as near as poss to the enterance is prob favourite, and to bag a good spot in the stands for the action, and for photography. I reckon a packed lunch and flask of coffee is a safe bet.
