Akron half marathon

This past Saturday, I ran in the Akron half marathon.  Other than the ironman in July, it's the 1st long race I've done in awhile.  I really, really enjoyed it!  What a great race!  I would highly recommend it to anyone who is thinking of doing a half marathon.  The organization is great and the perks are nice.  The course is really pretty with lots of crowd support and volunteers. 
Mark and I got up at 4:30 AM in order to get there in time for the 7AM start.  We got there at about 6:15 AM which was plenty of time to find parking (we parked at the Children's hospital, which is only a block or two from the stadium finish).  And plenty of time to find a good place at the start.  The race start of 7AM is for everyone - marathon, half marathon and relay runners.  So it was very, very crowded.  I'm not sure what the total participating in all 3, but the half marathon had about 3700 runners. 
My goal was to do the race in 1:50 or better.  And at mile 5, I thought I was on pace to hit about 1:45 - I felt great and was clipping along at about 8 min/mile or less.  Then I had to make a porta potty stop.  And unfortunately, since there wasn't a porta potty in sight, I had to stop and walk.  And unfortunately, after that stop, I had to make 3 more.  I'm not sure if it was the power bar not agreeing with me, the red bull, or the burger and fries I had the night before.  But something wasn't sitting well.  Anyway, I ended up with a 1:51 time.  So, I was happy with that as I was running well except when I wasn't running.  ha ha. 
All in all, though, it was a lot of fun and I felt good (most of the time).  It really made me realize how much I love to run.  Although triathlons are fun, my real love is in the distance running events.  Mark was laughing at me, as I came home and started looking up other half marathons.  I haven't decided what's next - but I think an early spring half marathon OR marathon is in the works.  Any ideas?
