Sorry, I was off-line there for a while.
Min is obviously right about lifestyle change being difficult. But surely it is attitudes of others that also hold us back?
It used to be perceived as unacceptable for women to breastfeed in public. This is no longer the case in most areas, I think? I certainly never encountered any explicit hostility/rudeness etc. And of course, it is now illegal in Scotland for people to not let you feed in restaurants etc.
But, as we have noted, it is certainly still acceptable to vent anti-cycling attitudes in public. Perhaps that's what has to change. Another lesson must be that the breastfeeding lobby moved beyond their image of hippiedom and had the WHO, NHS on-side. Now a much largeer proportion of mothers at least start breastfeeding, but often don't carry on for as long as they 'ought' to. This is where I think the comparison with cycle-chic and cycle-training comes in. If you make it look glamorous and easy, then people are surprised that it is uncomfortable to start with, and get discouraged easily. So you need people who can advise, support and help you. Now breastfeeding clinics and trainers are much more widely availaible - at the ERI and at GPs clinics etc.
We need attitude change, but realistic attitude change -- there will be setbacks, you might have a fall, get sweaty, your bike will breakdown, etc, but wit support, you can keep cycling. That way, attitude change might translate into lifestyle change.
So my two lessons for cycle campaigns are (1) we need the NHS, govt, etc on board and (2) maybe we don't need 'training courses' so much as 'cycle advisors' that you can ring up and ask for advice, when the going gets tough. Rather, in my case, how this forum has encouraged me to cycle in the snow, when I probably wouldn't have, and given other bits of advice!
(an aside: I cycled my toddler to Sick Kids after she'd had a fall earlier this year -- it was the only practical thing to do as we were out on bike at time -- and can certainly imagine myself cycling to check-ups; actually cycling there in/for labour strikes me as a bit more difficult! I would not want to cycle home again afterwards!!)
