I started off on a comfortable pace. About 9:30 per mile. I took walk breaks every 10 minutes. I felt pretty good after the 13th mile, and my goal was to at least stay under 10 minute miles heading into the higher miles. At mile 16 was a pretty steep hill. I took the hill at a good pace, and I was still feeling pretty strong. What really started me going even stronger was when I paced the pace setter for 4:15 runners. I start thinking to myself that I might even have a slight chance of breaking 4 hours. That thought went away at mile 20. Even though my pace was still under 10 minutes, I realized at this point that I didn't have another gear to kick in. So my goal now was for 4:10. My legs where really starting to burn at mile 23, and at mile 24 was a very steep down hill. That down hill really made my thighs burn. I was trying to fight gravity, so that my thighs wouldn't take such a pounding.
I want to thank the group that was giving out beer shots at mile 25. Having that shot of beer was a nice motivator to make one final kick towards the finish.
