Friday - run 3.6 miles

I am contemplating signing up for a 12-hour event in March. The run is on a 1 mile course and I think I could probably go for about 50-55 miles. So I've decided to start training as if I am doing it. With that in mind, I chose a 1.15 mile course so I could run some loops. I didn't have a lot of time, so I ran for 30 minutes and made it just past 3 loops. I felt pretty good though. My loop splits were 9.48, 9.49, 9.52 so there wasn't much drop off and I'm pretty sure I could have gone a couple of more without wanting to quit. That's my problem right now. Anything longer than 3 miles and my mind starts screaming enough. It was probably my mind that suggested I didn't have time to go longer today!
