Had a very nice ride through Dedham Vale despite headwinds the whole way. Just when I was considering stopping, I had a flat. I had planned on doing 40-45 miles. Flat occured at 39.99miles. I figured that was close enough and caught the train the rest of the way home. The sun had set by then anyway and it's not very nice out on the country lanes alone in the dark. I'll have to try to get started earlier next time if I want to add any more distance. Damn. I hate getting up early, especially on a Sunday.
