For those unfamiliar with this event wishing to qualify for the trophy you must ride in a gear restricted to 72 inches. This means that for one revolution of the pedals you can only cover a distance of 18 feet 10.3 inches or 5.75 metres. If you are going to use a multi geared cycle the derailleur will need to be ‘screwed down’ or ‘tie wrapped’ to restrict changing gear. Typical ratios that are OK are 48 x 18, 45 x 17, 42 x 16 and 52 x 20. A quick method of establishing the distance is –
 
• Mark out the distance (18’ 10.3” or 5.75 meters)
• Engage selected gear ratio; line up 1 pedal with start of measuring distance, reverse wheel your cycle until 1 revolution of the pedal crank is achieved.
• If one revolution is achieved before reaching the end of measured distance then the selected ratio is OK. If not try another ratio. If one revolution is achieved with a considerable distance to go try a higher ratio.
 
For those who do not wish to qualify for the Trophy event, but still wish to have a go at the Time Trial, feel free to come along and ride an “unrestricted” 10 Mile Time Trial on any bicycle.
