I had to pick up a bike today and deliver it 10 miles across London. Easiest way to transport a bike from A to B is by riding it, of course, so that's what I did.
Lovely lightweight aero road bike, designed for going proper fast, so of course I fitted a pair of manky old flat plastic pedals because a) that's what I had available, and b) I was in trainers, not cycling shoes. And it was absolutely fine. I think the cassette must be a bit worn, because at one point when I changed gear the chain skipped and that caused my foot to slip slightly, but I didn't fall under a bus or anything silly like that. Phew!
Also, I didn't wear padded lycra shorts, just my normal everyday jeans, and no lump of plastic on my head either. It's almost like you don't actually need this stuff to be able to ride a bike...
Having said that, I will of course be reverting to full MAMIL mode for this Sunday's club ride - lycra, helmet, sporty shades, clipless pedals, mitts, gels stuffed in back pocket. You've got to keep up appearances, right? Might even shave my legs.
