Total 24 Hours of Spa is high on my wish list of events I want to marshal in the near future. It is a premier event in the Blancpain Edurance Series in Europe, part of the SRO organized GT series of international racing. I know there is a large Belgian marshaling community that organizes this event with help from marshals from all over Europe and the world for that matter. I have been following facebook posts by British, Dutch, and German marshals that have done the 24h of Spa, and I am very jealous.
If you wish to share some information on how I should go about marshaling this event please do share it with me in the comments below.
