A mate of mine seems to thing that its down to my age and that I will never be able to improve.
He's pretty much correct, unfortunately.
While it is possible in some cases to set about a training programme to improve on static or declining performance in any sporting endeavour, any resulting improvement can only be short-lived. Sadly, the effort, both physical and mental in order to maintain a very high physical output level in middle age is more demanding than most of us wish to suffer.
That is why no older rider has ever won the TDF and why footballers over 40 are unlikely ever to score the winning goal at Wembley. As you know, I'm sure, swimmers peak quite early and are usually long past their best by 30. Sprinters peak from late 20s through to early 30s and cricketers generally don't function so well past 35.
Cycling, whether as sport or high-intensity training is a very demanding, muscle-sapping workout so hats off to those, rather unkindly named, MAMILS, who keep going out there and doing it in that hair-shirt way that they do. I'm a leisure-cum-utility cyclist and with a collection of debilitating disabilities to my name and shame, I just do what I can. If I could walk, I'd do lots of that as I used to enjoy it. Cycling is a different kind of action so I can do more of that than walking and there are always opportunities to rest the legs thanks to gravity while on a bike.
Many fight against the onset of ageing but while it's a good idea to stay fit and active as long as we can, the fight is futile. Nonetheless, we can grow old gracefully because of all that we have learned and continue to learn. The U3A is testament to how well older people can cope in many, many ways. It's a university from which nobody graduates but none of the students care! They just enjoy the journey in good company. How nice is that!
