In the programme for the SeeRed meeting at Donington Park in September 2005 was this note:
THE PIONEER SPIRIT LIVES ON
The commemorative Grand Prix Run is for cars built from 1906 to '14.
The road event will run over approximately 30 miles. The first car will be
flagged away from the Donington Collection at 9.30am on Sunday.
Look out for these cars on track during the lunch break as they circulate
to collect marshals from their posts.
This is one of the cars, a 1906 Mercedes 60hp, delivering one of the marshals back to his post after the lunch break.
