Now as to the mockery of the weather gods, one reason that the fairing went back on was to cut down the wind chill on cold mornings. So, no wind and a quite mild 9 degrees celsius this morning. Apparently it is going to be like this all week. :)
Finally the new personal trainer has me doing some leg work which will probably boost my power in the long term In the short term, trying to put on a power sprint after a session that involved calf raises and leg extensions is an exercise in futility. :)
