Having been to Club room last night I had the privalage of looking at a Time Trial stating list from 1948.
The starting point was at Sanderstone Hill Oppisite LAMP POST NO1449 and the turning point was the FOURTH TREE down wherever(can't remember sorry) but Back then not only did you have to worry about all the other riding stuff you also had to count trees so you didn't miss the U TURN ....how things have changed for the better I think.
