Changing temperature

It was almost 80 degrees this afternoon and I spent most of it doing yard work.  I met up with the group this evening at the park and ran 2.5 miles on the trails.  Now, it's 52 and is suppose to get down to 34 tomorrow night.  My next race is a road race from Kilgore to Longview (11 miles) on Saturday.  Just hoping for a trail wind.
