In Michigan the weather can change quickly. So when the temperature jumped to 80 degrees from the mid-50s in one day I was ready for the season’s first run in shorts and t-shirt. As I headed out to do eight miles in the noon sun I was feeling great. In the cloudy, cool days of late winter I can do eight miles without breaking a sweat. In the glare of the first sunny day in months it was a different story. About three miles up Woodward Avenue I was wet with sweat and breathing hard. As I turned around and headed toward home I knew this warm weather running was going to take some getting used to again. But I’m looking forward to it.
