I used to commute in the rain. If it happened, it happened. In cool weather, I found that if I put on my waterproof socks and raincoat I would be fine for close to 9 miles. (thank goodness for fenders) This is usually the go to plan in the rain. If it was warm weather rain, I would ride most days. Especially, if it was light rain. I would wait out stronger storms.
