microphonie, that is seriously fast!
My friend is trying to 'get fit' and has taken up cycling with her mum. The route they always take is just under 15 miles up to the local cryptosporidium depot (Pitsford resevoir), round the track and back.
They did it on Friday when I was at school ... no trouble. On Monday I went with them, taking clobber like a P****** repair kit, some strange multitool thing of my Dad's, a Swiss Army Knife and a first aid kit.
So on Monday we rode up to the resevoir. 3/4 of the way round my friend's mum breaks her chain. I have never done a chain repair before, and try to fix it before phoning my Dad, who picks my friend's mum up and takes her home whilst me and my friend cycle home.
My friend's bike has very aggressive brakes, and doesn't like to use her back one for some reason. So today she went over the handlebars, twice. The first time, about 600m from my house, I used my Dad's multitool thing to take her rack off, which had bent so the wheel couldn't go round. Then her mum dropped it off at my house and we went on.
Halfway round my friend came off again, and grazed her hand (no mitts) and her knee pretty badly, knocking her chain off. A little first aid and a fiddle with the chain and we're off again, but pretty slowly. I asked her whether she wanted to take up cycling as a hobby, but she says she doesn't really like it and is just doing it to get fit.
