I've been rubbish on the bike in the last couple of weeks, feeling a bit tired. Figured it might be because I'm putting a bit too much effort into my commuting and not recovering properly. Rode in today in 42x23 and tried not to open my mouth the whole way (I failed a couple of times because of uphill bits and accelerating out of junctions, but was mostly successful). Hardly even felt the ride in, but it was surprisingly difficult to ride so slow. I'm going to see if I can stick with it for a few days, see how it works out. Strangely I arrived at work at much the same time as usual. And I still overtook the one cyclist I encountered today, although he was wearing an enormous quilted coat and pedalling with his heels. Now waiting to see if I can resist when someone overtakes me.
