I just checked for forecast for the weekend. The weather for the 10-miler in Conroe on Saturday is 33 up to 39 degrees and a 30 percent chance of rain (freezing rain). For the marathon in College Station on Sunday, its 37 to 45 degrees, with a 30 percent chance of rain. Sounds okay.
It was 39 degrees with a light mist when I went out to the park this evening and I ran 2 miles on the park roads. No one else showed up.
