Two days ago I did 37 miles. My legs felt quite heavy and it was quite hard work.First time out for over a week.
Yesterday I spent the whole day working on my bike -details on the what have you fettled today thread, but one of the bearings on the BB was sticking and I replaced the cups and all cables. Today I did the same route, expecting a noticeable difference. For a while in the middle I was ahead on my time, but ended up almost exactly the same as two days ago. I had a slightly worse ride today for traffic lights, but there really wasn't anything in it. So grinding my axle into gray paste clearly doesn't make much difference to my speed.
