Train in the Rain

You never know what to expect on race day. The 2007 Chicago marathon presented runners with exceedingly hot temperatures by October standards (see below).

By the same token, the Marine Corps Marathon could see rain, heat, or day I say it, snow?

Just in case, Fit Sugar recommends that you train in every possible climate to make sure you're ready for the conditions on October 25th. See it raining? Pop outside for a quick run. Hitting 95 degrees? Test how long you can handle it. You never know what you're gonna get.
