46f (8C) today, and a pretty morning. I have been on my bike for 2 weeks, with work and a bike trip last weekend, and my energy levels have been gone for days. My legs, which usually have a mind of their own, needed me to step down gears going up hills, and moving fast to get out of the way of cars making a right. 2 days off for the weekend will be the prescription. Bike to work in this area is next friday, and this week coming has been designated bike to work week.
