Next years sees the 100th anniversary of the Mountain Course, Peel author David Wright is compiling a fascinating history of its history.

Bill, I have no doubt that the IOM surveyors department know exactly, perhaps to the inch, the length of the TT mountain circuit. Perhaps I should ask them !

I've seen many suggested methods of measuring the course including scaling off maps, odometer readings, gps etc but in my opinion as realistic a method as any would be to drag a calibrated trundle wheel around behind a car. Repeat three or four times, average the readings and see what you get. I've been meaning to do it for several years but as usual life got in the way.

Of course, the most accurate method would be to observe a traverse by total station right round the course detailing the centreline as you go. I estimate I could do it in 8 days and I'm more than happy to provide a quote if asked. I would suggest June or August as being ideal times!
