Five days in work this week (Sun-Thurs) and for the first four I was able to use my road bike as it's been unusually dry in South Wales recently. My commute times have plummeted due to a combination of riding a much lighter bike without fenders and I'm quite a bit lighter myself as I've been on a bit of a diet since Jan 1st losing 17lb by doing 'dry January' and stopping eating sweets, crisps and biscuits (in the USA I think this is candy, chips and cookies). I've still got a long way to go though as my BMI is still 32.7 and firmly in the 'obese' classification.
I love seeing the days slowly growing longer although I'm only catching the benefit on a morning as I'm still working long days (11 hours).
