Crazy run today

I had my partner pace me on her bike today for a little test to see how I would do. Nothing competitive but I wanted to see how I could go for 14km. I went out well, real comfortable, easy stride. I picked up the pace to about 6k where I started to feel some serious fatigue, from my day, the heat and the lack of water. I ran through it well enough but it came back again in about 4k. That time was harder to deal with but I didn't let it beat me. I pushed all the way to the end and felt like hell doing it. But it was a success in the sense of completion and not stopping cause I was tired. Good for the mental aspect. 1:06:39 ~ 14.1 km, 4:44 per km.
