Zeitgeist Half Marathon

I did the Zeitgeist Half Marathon yesterday, which was my first Half Marathon in more than 15 years. I didn't realize how hilly of a course it was until after I signed up. The first 8 miles were uphil (3 big hills with about 1200 feet in elevation change -- its the same "dump loop" Cory and I ride when we do our hills cycling) and the last 5 miles were downhill. I prefer flat courses, and I haven't run a single hill in at least 3 months, so I am feeling REALLY sore today. Out of a little over 1000 runners, I was 35th place with a time of 1 hour 33 minutes.
