Placid on the outside, raging on the inside

To Upper Thomson Road, 22 km. On the outside, I look like someone on a leisurely ride. On the inside, I'm disturbed. My back hurts; it's been so since 18 Jun after I break the cardinal rule of using new equipment (in this case, my saddle) on an expedition only after it has been extensively road-tested and adjusted. Or perhaps it's psychosomatic: my work is back-breaking. This morning, I wake up at 2 am to write an office email ... And because of work, I decide not to go for an advanced mountain bike clinic this Fri. Which is just as well. Like bikeshop man says today, after adjusting my rear d for the 4th time this year, it costs money to ride.
