My 3rd Marathon

As a runner, I've always been told you will have good days and bad days. Well Yesterday I will call a bad day. LOL
I ran my 3rd Marathon (41st Annual ORRRC Marathon) Xenia, Ohio. The weather started out questionable. On/Off thunderstorms expected and temperatures in the mid 40's.
The race started off at 8:30 AM. There were 333 people running the 1/2 & 143 full 26.2 mile marathoners that finished. I started out good & running a pace that just felt ok for that distance. At the 1/2, I was running around 1:54 which was alittle quicker than I thought. We hit several roads were the wind & sleet were stronger than any I had run it yet.
The problems all seem to start around 14 miles. I started to feel a little dizzy. Not good, a sign of dehydration. I took a few jell packs & downed more water but I knew I was in trouble. My legs started cramping next. My left hamstring was turning into instant pain. I'd slowed down just to try & help. But it was to late! I would run between a one or two miles & the hamstring would just lock & want to stop me in my tracks. Wow, that really sticks, I felt good other than that. I ended up finishing at 4:30:57 at a 10:21 pace. Not terrible, but just not what I was hopeing for. Oh well, the year is young. I will do better. Maybe the Toledo marathon in two weeks....we'll see how it goes.
