First race since 2009

Did a 3 mile race today (my Garmin GPS watch said it was 3.07 miles) in 26:45 - 8:43/mile.  I started slow and then tapered off.  The course was mostly flat but even the slightest uphill slowed me down to a crawl. It might have been the longest 3 miles of my life. I'll try another race if I ever get below my current 185 pounds.
