Cooper River run

Cooper River Bridge Run
A race I would like to do in Charleston. Like 30,000 runners. If I don't do it this year then next year. It is 10k or 6.2 miles. They want you to commit to 49 minutes or less or 50 to 70 minutes. Right?  So 49 minutes gives a 7.9 minute pace or 7:54. 

Not sure I can do that pace. Climbing the bridge could be tough. That should be my goal though. I need a 7:48 pace to qualify for Boston.
