Let's see...
Hit the Highlands with Ken and Kenny, headbutted Buckinghamshire, and broke my thumb, rode LonJoG with The Fridays lovelies; a real life changer, did a few FNRttCs inc. one on a Brompton and one on a fixed, and a couple of rides home, did Cardiff-Swansea for a bit of international flavour, rode a trans-cambrian off road, visited some trial centres, commuted to work a lot, saw an osprey, chased Ross across Yorkshire, fell off for no good reason on road three times, fell off for no good reason off-road countless times, led an informal forum ride, almost had a fight with a fellow cyclist in London, had handbags with an Audi driver in Sussex, ate a curry, drank some beers, sold two bikes, bought a full-boinger, dislocated a shoulder, laughed a lot, cried a bit esp when putting the shoulder back in, made some new friends, increased in my admiration and respect for the existing ones. Developed a crush on Emma Pooley. Watched some mod win a gold medal and a yellow jersey.
I can't remember many of the miles, the places and the sights. I can, and I hope will forever, remember the people.
As my cycling years go I'd give 2012 about 13.5/10.
