I didn't ride for the last week and a half. I took a long bike trip several weeks ago and because of work and the weather changes I made lots of excuses not to ride since then. The sun comes up a lot later now and it's almost dark at 6:45 PM. You name the excuses and I used them.
However I took off from work a little early yesterday and got in a quick 30 miles. I stopped only when it got too dark. It felt great. I was really rested and it felt effortless. This morning I feel better than I have felt for days.
Don't listen to the excuses. Go out and ride.
