The annual YMCA "Re-Tread" 5k run/5k walk  is Thursday night at the downtown Flint "Y" location.  Race starts at 6:30. 

You can sign up until early afternoon Thursday at Bauman's Running shop on Hill road, then at the YMCA from 5 pm to race time.  Course is flat and fast through the College/Cultural area and the weather forecast is calling for cooler temperatures on Thursday.  Sounds like a good day to go for a personal best!  Running races is great training for the Crim, which is just over two months away.
