I just hope I can ride or run at 72! There is nothing fraudulent about it. You could go out and buy the lightest bike on the market with the easiest gearing on the market to get you up hills, but you would not get enjoyment and would struggle to keep up with others, especially on flats. At the end of the day sport is for all - regardless of age, ability, physical impairment or size. Most importantly it is about enjoyment, and at whatever level you are at if something assists you in continuing to do something you enjoy, to a level that makes you happy, then who is anyone to say otherwise. Pro's look for any advantage to gain an edge. In swimming certain costumes have been banned due the advantage they gave athletes, but for a few years they were used, however, it did not make those pro swimmers frauds. Lyndsey Vonn skied on men's downhill skis in women's races because they were stiffer which gave her an advantage, Phil Taylor trained with a specially made dart board where the double and triple sections were narrower than on a competition board, a 72 year old at my snooker and pool club used to play at national level but now uses a cue that reduces throw and deflection as it improves his game because he now finds it harder to aim. I would not say that any of these would be considered frauds. They are just making use of what is available to them to do what they enjoy at the level they enjoy. I just love talking, meeting and seeing people who are overcoming whatever impairments they have to continue doing sport, and also people who are pioneers in training ideas and use of equipment developments. It would not surprise me if in the future bikes like these are used in various training environments across a range of sports at varying levels. For me it will be the perfect tool for base training in running, whilst reducing the injury risk caused by pounding the pavements for 40 miles a week in my running shoes. It will keep my heart rate in the correct zone whilst being able to get out and explore with friends. Anyway, looking at your times and speeds of the rides you have posted, they are faster than I can ride and you are nearly 30 years my senior. There is nothing fraudulent in that my friend. Keep up the cycling and the good work!!
