Don't know why, but went for my usual ride this afternoon of about 20-25 miles, but today I felt at one with the world. The sun was shining, the cages were few, the hills were flatter and the hassles were none. Everything was smooth, silky and serene. Got back and felt top of the tree. On top of that, I did my best ever time for the route. What is it that makes these kind of rides so rare?
