Following the big cycle on Sunday, I've been pretty dead - body just tired and generally feeling sorry for itself. Thankfully though, no lasting trouble from the cramps and I've cycled to \ from work both days.
Just thought I'd add a little postscript about an incentive scheme I have for 2011 - the idea is to get a new bike sometime during the year. So, I've decided that any day I cycle to & from work I contribute £3 towards a new bike. The reason for £3 is that it's approx. the cost of a return bus ticket to work. So far, I'm up to £9 :)
