My training schedule

Here's a link to my training schedule. I'm training for the Great Turtle 5.7 mile run on Mackinac Island. I plan on sticking very closely to it. You'll notice that it has me running 182 miles including the race between now and October 21st. That's a lot of miles. I've been thinking about looking for some sponsors to help me pay the registration and hotel. Do you think this is a good idea or not?
