Rode out to Lambourn from London along the Thames valley on IDDU's new EWE Baa 200km perm, aided and abetted by Mattc who joined me midway. Clear skies, low wind and single digit temps (oC) made a grand winter ride. I tend to overdress when the weather is cold but got things about right for once, two layers of merino plus longs being just enough to keep the chill off. Mostly flattish so a chance to work on spinning a larger gear. I get the feeling this will be a useful 'reference' ride... be interesting to see how things are going when things start to warm up in the spring.
