Annoying pattern

So the way it has been lately is: I hate, hate, hate riding my bike for the first 10–12 miles. I feel pokey, slow, heavy, slow, sludgy, slow, and slow, and slow! I can’t think of WHY on earth I think this is a fun thing to do, and I panic. Because I’m going to be doing A LOT of it. Then I hit mile 15, and hey, maybe the wind has changed. I look at the cycle computer. I’m doing 16 miles an hour. It doesn’t hurt anymore, my lungs are no longer burning, and my legs are saying, "hey, we remember how to do this now!" And I finish my ride feeling fast and svelte and triumphant. I just have to get through those first miles! I was completely ready to quit, but I knew I couldn’t. Maybe I should make a sign for my bike:  "Wait for it!"
