I'd love to be 11 st again (70kg) but realistically 75 is a target I think I should be able to achieve. Like you though, I'm concentrating on power and technique and hope that the volume of riding i do will lead to gradual weight loss too.I was around 10.5 stone so 68 kilos until my mid 30’s. 70-72 kilos Is not unreasonable given I have lost some upper body muscle mas with age and concentration on cycling. Any less than that though would mean giving up too much of what I enjoy in life and , other than for a Marmotte or similar is simply not worth it.
Best to work on power and technique.
With HID being so poorly i rarely drink these days, even more rarely go out with mates for curries, but do still succumb to too many cakes! Riding is my outlet from my carer responsibilities so I have to do it to enjoy it and not as a chore.
