How to become a marshal in the UK?
Join the British Motorsport Marshals Club to volunteer: http://www.marshals.co.uk/
My first marshaling experience in the UK was the 2013 British GP at Silverstone. I had a fantastic time though I had to nurse an injury which prevented me from working incident response like I was assigned to, so instead they allowed me to be a flag marshal which was uber cool of the Silverstone marshals.
If you have any information about volunteering in the UK, please share in the comments section below or contact me privately and I’ll be happy to put your info on this web site. Thanks!
