Am heading out this afternoon for a 16 mile ride with my personal trainer and his wife - it will be a beautiful afternoon for it - though not very warm. It will be in the high 50's when we get started, and it won't be warming much at all. There will be a fair amount of climbing on this route though, and am wondering how to dress.

I figure I will need my jacket, I wore it yesterday in the park and was comfy - though I wasn't working as hard as I will be this afternoon. It is my legs that I am wondering about - I have my nice new baggy shorts from TE that I would like to wear for the first time - but is 57-60 degrees too cold for shorts? I am thinking that it will be fine, but wondering how others deal with these in-between temps.
