Similar weather here about an hour north of you RT. I went with just shorts. It's funny, when the weather hits 50°F or under I'm freezing and wear tights, long sleeves, gloves, a hat, and maybe even a jacket but as soon as 60° hits I'm dying and need to run in as little as possible.
I got on 7 miles and some strides. I need to start taking in more calories, I'm feeling a little sluggish and don't weigh what I think is healthy.
