I go as fast as is safe. When there's hardly any room to move between packed cars, I go a lot slower than when the road is flowing freely. On a descent, I go as fast as is appropriate for the road surface, and on a climb I go as fast as I can. I daresay that you'd condemn me as a reckless cyclist were I to blast past you on the road. However there are races to be raced, and I won't learn to go faster unless I do so at every reasonable opportunity.
