The 2018 Royal Automobile Club 1000 Mile Trial set the standard for pre-war motoring events. 1090 miles of the best roads in Britain, 27 regularities, 19 tests and 30 of the top crews battling it out over six days. More information is available here.
The original 1000 Mile Trial was organised by the Royal Automobile Club in 1900. It started in London and followed a route through Bristol, Birmingham, Manchester, Derby, Kendal, Carlisle, Edinburgh, Newcastle, Leeds, Sheffield, Nottingham and back to London. There were 83 entries of which 65 actually started. By Edinburgh 51 were still running and 35 vehicles made it back to London.
The next 1000 Mile Trial will take place in 2020.
