This is one of the reasons why I cycle;
mmmmmm and totally worth it.
Good 3hr ride today to the Ming Tombs, the route, not technical, is a boring one, but one for MP3 players.
It follows the Beijing Olympic Road Race route, not the good steep part at the end, but the flat bit at the beginning.
It's my first long steady ride for some time, so I was very happy with it.
More later.... I've got a muffin and a coffee to finish first :D
