Competitors at the 2012 U.S. Marathon Olympic Trials will toe the line right around 8 a.m. local time in Houston on Saturday, and it looks like the weather will cause no real problems as we sit less than four days out. But this is Houston, and it looks like it will be a bit more warm than, say, New York or Boston.
Weather.com lists Saturday's high in Houston at 67 ... which is fairly close to the average temperature in London in August. Last year's Houston Marathon -- which will be run Sunday to complete the runners' weekend in the city -- was damp, but the temperatures were mild.
Rain looks to be unlikely for Saturday, but temperatures could creep up above idyllic (40s) into imperfect (50s). I think the competitors will be without complaint about the weather either way.
NBC will broadcast the trials on tape delay Saturday afternoon. The men will take off at 9 a.m. ET and the women will follow 15 minutes later.
