Why do they call it mini?

On saturday Drew and I ran the Indianapolis 500 Mini-marathon, and all I have to say is the only thing mini about 13.1 miles is the length of the shorts 90% of the people were wearing. I mean, come on people, there should be a law against shorts that short.We had a great time, we ran the first 7.5 miles, walked the next 3, and suffered through the last 2.5 miles. Overall it was incredible we even finished it considering I hadn't ran a mile since October 2006. Also, my "I just had a baby" shirt fell through so I couldn't rely on that for pity. We finished in about 2 hours and 55 minutes: Rock on runners!
