I have been advised that the VTTA have published a new set of standards for veteran time triallists. They can be viewed on https://www.vtta.org.uk/standards .
Some adjustments have been made to the 2013 figures, shortening the required times in some cases and lengthening them in others. On balance ladies fair better than men on bicycles. The good news for us riders of the stable machine is that all standards have become easier to attain on a tricycle, whatever your sex.
