I went, it was a nice few hours out. Not a huge amount of track activity but well worth going and great weather too
Did anyone go? Hope it was a good day out.
Just turn up as its not a ticketed event. I shall pop along as its local for me
The only location mentioned in the article is "The action will run from 9am to 5pm with fans granted access to the international pit-straight grandstand." No sign of registration, but having gone to Silverstone last year there are multiple activities and buildings you can access most days both within and immediately around the circuit, so there weren't any entrance checks (wasn't a race day). While most of the seating grandstands will likely be closed, Silverstone has plenty of space around the circuit with good views for the cars going round so space really won't be a problem.
